📌 The famous bitcoin enthusiast and TV presenter Max Kaiser expects the price of the first cryptocurrency to rise to $ 28,000 soon.submitted by VS_community to pyrk [link] [comments]
📌 Popular cryptanalyst Plan B, using the Stock-to-Flow (S2F) model, has calculated that Bitcoin will reach this mark by the end of 2021.
📈 The main driver of growth for the cryptocurrency market was the halving of the bitcoin miners' reward. Most investors expect a sharp rise in prices in 2020-2021, which was associated with the general optimism in the market in the middle of the year.
🤵🏻 Many prominent figures in the financial world, such as the head of the Bank for International Settlements Augustine Carstens, the head of the Bank of England Mark Carney, the economist-historian from Harvard University Niall Ferguson, and the president of the brokerage company Euro Pacific Capital Inc. Peter Schiff, have changed their negative attitude towards cryptocurrencies to neutral or even positive.
💰 One way or another, this year the market expects a lot of events that should have a positive effect on the investment attractiveness of cryptocurrencies.
📈 Today, it is still difficult to predict the future of cryptocurrencies in the long term, but if traditional stock markets suffer in the near future, then the prices of cryptocurrencies as an alternative means of investment can skyrocket many times, and this should also be taken into account when financial planning for 2021 and subsequent years.

The concept of finance is not new, it has been in existence since the earliest days of the exchange. Everyone has the opportunity and ability to be successful if they have the right resources, however, one of the most challenging aspects of building a business is financing it and many often struggle in their endeavour to raise the capital required.submitted by Cryptosavvy_001 to u/Cryptosavvy_001 [link] [comments]
Over the years, the concept developed into a centralized system allowing users to trust their assets (money and any other forms of wealth) to 3rd parties with the goal of receiving monthly or yearly interest.
This concept was great while it lasted but as usual, the only thing that remains constant is change.
Cryptocurrency and Blockchain came into existence some years back as a medium to pay for services rendered via digital currency. Bitcoin, the very first Blockchain, was created but served as a one-way payment medium and nothing more. However, developers saw the vision that something more could be achieved using this same technology, but with more features being included. These were called smart contracts.
Smart contracts do not require both parties to be present, they are automated and use real-time data to generate the result.
Ethereum brought this to reality and a few years later, others saw this opportunity and started making use of it to build DeFi apps, which would later become more preferable to CeFi.
Decentralized finance, or DeFi for short, is a general term used to represent financial applications or platforms that are built using one or more Blockchain, that make use of smart contracts to create higher returns on investment.
DeFi alone is a great investment option, but the major challenge it has faced so far is a lack of users or a limited number of users whose sole aim is to increase their vested capital. Up until now, it has not been community-driven, which would create something far greater. Tweebaa intends to achieve this.
What is Tweebaa?
Tweebaa is the world’s only earning commerce platform. Its revolutionary multi-dimensional ecosystem utilizes a value-exchange model and provides everyone with the means and opportunity to generate a substantial income. Tweebaa empowers its users by applying their winning team's proven success methods with “DRTV (Direct Response Television)” and helps bring a global network of traffic to their product or business! Tweebaa has all the great communication features you would want within social networking and of course the best marketplace too! Tweebaa paves the way for users to earn money in a variety of ways whilst also providing the emotional, financial, and social benefits that are often unavailable; all this in one app! Whether you are a business, a student, a seller, a homemaker, an influencer, a labourer, or a contributor to society, Tweebaa rewards you every step of the way!
Over the years Tweebaa has distributed wealth to both investors and users alike via its token called TWEE and has remained at the forefront of trends and latest developments. Tweebaa is going DeFi (TweeB) and promises to create a revolutionary system the world is more than ready for.
What is DeFi?
The definition might vary when asked by different individuals, but they all come back to the same meaning; decentralized means to render services such as lending and borrowing with no 3rd party involvement, restrictions, delays, the line waiting, and long queues.
DeFi is currently the most talked-about project echoing around the crypto space. Many are raving about it, while some are still critical.
DeFi farming has to do with individuals providing some form of liquidity to the market which in turn creates returns and keeps the market active. It gained massive attention when it came into existence and is still active and a hot topic of discussion today.
Tweebaa is introducing a new token called TweeB which included all the features of a DeFi coin. Tweebaa users will be able to explore and make use of this newly discovered global network.
What makes TweeB so unique?
At the moment, decentralized finance is mainly directed to an investor's interest with the sole aim of investing or rather putting in money and waiting for results (short-term). One can argue that it has yet to actually become a general platform when compared to centralized finance like the banking system, which offers services for every type of person. TweeB plans to reach a much wider user base, not only including the general cryptocurrency investor pool, but also the entire global network available through Tweebaa.
Using Tweebaa’s existing community, TweeB will create something that is totally different and rewards all users, both depositors and borrowers.
Whether you provide liquidity, lend to the TweeB platform, or make use of its borrowing services by providing crypto supported collateral, users can yield returns, regardless of which direction they decide to take.
Combining the power of Tweebaa and TweeB, the more TiV a user holds, the more interest they will generate.
What is TiV?
TiV is an influence value, which reflects a user's contribution to the APP. People can increase their TiV by using the app in various ways including; adding and purchasing products, engaging and networking with other tycoons, inviting friends, and more.
There are many ways users can increase their TiV performance
In the field of DeFi in Tweebaa’s ecosystem, the TiV value is similar to the credit value and plays a vital role in relation to TweeBuck (TweeB).
What is TweeBuck and how will users be able to make full use of this platform?
TweeBuck (TweeB) is the next generation upgrade from its token holders. All potential changes, including adding new marks or adjusting system specifications (for example, leverage factors or interest calculations), must go through the proposal and voting process.
TweeBuck (TweeB) is a token which embeds 1:1 voting right to execute composite governance. Token holders of TweeB can simply delegate their voting rights of utility tokens on ERC-20 to their own or other people’s Ethereum wallets address.
How does TweeBuck plan to reward its users?
TweeB is basically a DeFi-based coin and it plans on providing more financial services, when compared to other types of decentralized finance platforms, using the following features and more.
Basically, users will be able to provide TweeB liquidity on a ratio of 50/50 to whichever coin it is paired with, i.e. TweeB/ETH, TweeB/USDT, and more depending on users and what they prefer.
As a liquidity provider, decisions on which pair to trade TweeB with will be totally dependent on users as it should when referencing a decentralized network.
While the above is performed, liquidity providers get returns in TweeB tokens as more swap is carried out.
As mentioned above, TiV plays a vital role when interacting with the Tweebaa platform. The more TiV you have, the more TweeBuck (TweeB) you will receive. The TweeBuck (TweeB) amount received will be based on 60% of the users Twee and 40% from their TiV.
By depositing assets to the Tweebaa platform, users will be able to generate returns that are paid based on the pre-calculated format using different scenarios.
More information regarding this can be found in the whitepaper.
Centralized systems like the banking sector, give out loans to customers and in return, those customers provide collateral which can include land, homes, and other assets. However, the world is going digital and so should borrowing.
TweeB allows users to provide collateral in cryptos like BTC, ETH, and other altcoins which then provide users with the assets they want.
They can provide collateral in BTC and take their desired coin to trade; this can be paid back and their vested collateral closed/removed.
TweeB token omics can be further broken down to self-governance. In terms of DeFi, this simply means users will be able to self-govern the TWEEB platform based on the vested amount they hold. This, in turn, creates a scarcer economy giving more value to the token.
Scarcity is one of many ways to provide value to an asset, take BTC as an example with only 21mil total supply. It has, over-time, created a self-sustaining market which depends on holders and how much they are willing to sell at that point in time.
The same can be said about TweeB. Holders will determine how much they are willing to sell or if they prefer holding it, they will have more scarcity and more value.
In conclusion, TweeB hopes to create a system that is both community-driven and investment-wise, resulting in a system that is far more prevailing than anything currently available.
While the future cannot be predicted, users are advised to carry out their own research before investing.
To increase the awareness of TweeB, different events will be hosted occasionally. To find out more and keep up to date, join the Tweebaa telegram channel(community) if you haven’t already.

ABSTRACTThe effects of the web by a number of companies have seduced a large number of users as these companies keep their data to prevent them from searching for alternatives. Likewise, these huge platforms have attracted applications to build their highest ecosystems before either severing access or actively opposing their interests when the applications became so successful. As a result, these walled gardens have effectively hindered innovation and monopolized large sections of the web. After the emergence of blockchain technology and decentralized cryptocurrencies, the need for applications to support decentralization has emerged. Several blockchain-based companies, applications and platforms have appeared in decentralization. In this research report, we will explain the approach adopted by the NEAR decentralization platform in designing and implementing the basic technology for its system. Near is a basic platform for cloud computing and decentralized storage managed by the community, designed to enable the open web for the future. On this web, everything can be created from new currencies to new applications to new industries, opening the door to an entirely new future.
1. INTRODUCTIONThe richness of the web is increasing day by day with the combined efforts of millions of people who have benefited from “innovation without permission” as content and applications are created without asking anyone. this lack of freedom of data has led to an environment hostile to the interests of its participants. And as we explained in the summary previously, web hosting companies have hindered innovation and greatly monopolized the web.
In the future, we can fix this by using new technologies to re-enable the permissionless innovation of the past in a way, which creates a more open web where users are free and applications are supportive rather than adversarial to their interests.
Decentralization emerged after the global financial crisis in 2008, which created fundamental problems of confidence in the heavily indebted banking system. Then the decentralized financial sector based on Blockchain technology has emerged since 2009.
Decentralized Blockchain technology has made it easy for decentralized digital currencies like Bitcoin to exchange billions of dollars in peer-to-peer transfers for a fraction of the price of a traditional banking system. This technology allows participants in the over $ 50 billion virtual goods economy to track, own and trade in these commodities without permission. It allows real-world goods to cross into the digital domain, with verified ownership and tracking just like that of the digital.
By default, the Internet where freedom of data enables innovation will lead to the development of a new form of software development. On this web, developers can quickly create applications from open state components and boost their efforts by using new business models that are enabled from within the program itself rather than relying on parasitic relationships with their users. This not only accelerates the creation of applications that have a more honest and cooperative relationship with its users, but also allows the emergence of completely new business built on them.
To enable these new applications and the open web, it needs the appropriate infrastructure. The new web platform cannot be controlled by a single entity and its use is not limited due to insufficient scalability. It should be decentralized in design like the web itself and supported by a community of distributors widely so that the value they store cannot be monitored, modified or removed without permission from the users who store this value on their behalf.
A new decentralization technology (Blockchain), which has facilitated decentralized digital currencies like Bitcoin, has made billions of dollars in peer-to-peer transfers at a fraction of the price of the traditional banking system. This technology allows participants in the $ 50 billion + virtual goods economy to track, own and trade in these goods without permission. It allows real-world goods to cross into the digital domain, with verified ownership and tracking just like that of the digital.
Although the cost of storing data or performing a calculation on the Ethereum blockchain is thousands and millions of times higher than the cost of performing the same functionality on Amazon Web Services. A developer can always create a “central” app or even a central currency for a fraction of the cost of doing the same on a decentralized platform because a decentralized platform, by definition, will have many iterations in its operations and storage.
Bitcoin can be thought of as the first, very basic, version of this global community-run cloud, though it is primarily used only to store and move the Bitcoin digital currency.
Ethereum is the second and slightly more sophisticated version, which expanded the basic principles of Bitcoin to create a more general computing and storage platform, though it is a raw technology, which hasn’t achieved meaningful mainstream adoption.
1.1 WHY IS IT IMPORTANT TO PAY THE EXTRA COST TO SUPPORT DECENTRALIZATION?Because some elements of value, for example bits representing digital currency ownership, personal identity, or asset notes, are very sensitive. While in the central system, the following players can change the value of any credits they come into direct contact with:
A typical user will trust a typical centralized application, despite its potential vulnerabilities, with everyday data and computation. Typically, only banks and governments are trusted sufficiently to maintain custody of the most sensitive information — balances of wealth and identity. But these entities are also subject to the very human forces of hubris, corruption and theft.
Especially after the 2008 global financial crisis, which demonstrated the fundamental problems of confidence in a highly indebted banking system. And governments around the
world apply significant capital controls to citizens during times of crisis. After these examples, it has become a truism that hackers now own most or all of your sensitive data.
These decentralized applications operate on a more complex infrastructure than today’s web but they have access to an instantaneous and global pool of currency, value and information that today’s web, where data is stored in the silos of individual corporations, cannot provide.
1.2 THE CHALLENGES OF CREATING A DECENTRALIZED CLOUDA community-run system like this has very different challenges from centralized “cloud” infrastructure, which is running by a single entity or group of known entities. For example:
2. NEARNEAR is a global community-run computing and storage cloud which is organized to be permissionless and which is economically incentivized to create a strong and decentralized data layer for the new web.
Essentially, it is a platform for running applications which have access to a shared — and secure — pool of money, identity and data which is owned by their users. More technically, it combines the features of partition-resistant networking, serverless compute and distributed storage into a new kind of platform.
NEAR is a community-managed, decentralized cloud storage and computing platform, designed to enable the open web in the future. It uses the same core technology for Bitcoin and Blockchain. On this web, everything can be created from new currencies to new applications to new industries, opening the door to an entirely new future.
NEAR is a decentralized community-run cloud computing and storage platform, which is designed to enable the open web of the future. On this web, everything from new currencies to new applications to new industries can be created, opening the door to a brand new future.
NEAR is a scalable computing and storage platform with the potential to change how systems are designed, how applications are built and how the web itself works.
It is a complex technology allow developers and entrepreneurs to easily and sustainably build applications which reap the benefits of decentralization and participate in the Open Web while minimizing the associated costs for end users.
NEAR creates the only community-managed cloud that is strong enough to power the future of the open web, as NEAR is designed from the ground up to deliver intuitive experiences to
end users, expand capacity across millions of devices, and provide developers with new and sustainable business models for their applications.
The NEAR Platform uses a token — also called “NEAR”. This token allows the users of these cloud resources, regardless of where they are in the world, to fairly compensate the providers of the services and to ensure that these participants operate in good faith.
2.1 WHY NEAR?Through focus, we find that Platforms based on blockchain technologies like Bitcoin and Ethereum have made great progress and enriched the world with thousands of innovative applications spanning from games to decentralized financing.
However, these original networks and none of the networks that followed were not able to bridge the gap towards mainstream adoption of the applications created above them and do not provide this type of standard that fully supports the web.
This is a result of two key factors:
Fixing these problems requires substantial and complex changes to current protocol architectures, something which existing organizations haven’t proven capable of implementing. Instead, they create multi-year backlogs of specification design and implementation, which result in their technology falling further and further behind.
NEAR’s platform and organization are architected specifically to solve the above-mentioned problems. The technical design is fanatically focused on creating the world’s most usable and scalable decentralized platform so global-scale applications can achieve real adoption. The organization and governance structure are designed to rapidly ship and continuously evolve the protocol so it will never become obsolete.
2.1.1 Features, which address these problems:1. USABILITY FIRST
The most important problem that needs to be addressed is how to allow developers to create useful applications that users can use easily and that will capture the sustainable value of these developers.
2. End-User Usability
Developers will only build applications, which their end users can actually use. NEAR’s “progressive security” model allows developers to create experiences for their users which more closely resemble familiar web experiences by delaying onboarding, removing the need for user to learn “blockchain” concepts and limiting the number of permission-asking interactions the user must have to use the application.
1. Simple Onboarding: NEAR allows developers to take actions on behalf of their users, which allows them to onboard users without requiring these users to provide a wallet or interact with tokens immediately upon reaching an application. Because accounts keep track of application-specific keys, user accounts can also be used for the kind of “Single Sign On” (SSO) functionality that users are familiar with from the traditional web (eg “Login with Facebook/Google/Github/etc”).
2. Easy Subscriptions: Contract-based accounts allow for easy creation of subscriptions and custom permissioning for particular applications.
3. Familiar Usage Styles: The NEAR economic model allows developers to pay for usage on behalf of their users in order to hide the costs of infrastructure in a way that is in line with familiar web usage paradigms.
4. Predictable Pricing: NEAR prices transactions on the platform in simple terms, which allow end-users to experience predictable pricing and less cognitive load when using the platform.
2.1.2 Design principles and development NEAR’s platform1. Usability: Applications deployed to the platform should be seamless to use for end users and seamless to create for developers. Wherever possible, the underlying technology itself should fade to the background or be hidden completely from end users. Wherever possible, developers should use familiar languages and patterns during the development process. Basic applications should be intuitive and simple to create while applications that are more robust should still be secure.
2. Scalability: The platform should scale with no upper limit as long as there is economic justification for doing so in order to support enterprise-grade, globally used applications.
3. Sustainable Decentralization: The platform should encourage significant decentralization in both the short term and the long term in order to properly secure the value it hosts. The platform — and community — should be widely and permissionlessly inclusive and actively encourage decentralization and participation. To maintain sustainability, both technological and community governance mechanisms should allow for practical iteration while avoiding capture by any single parties in the end.
4. Simplicity: The design of each of the system’s components should be as simple as possible in order to achieve their primary purpose. Optimize for simplicity, pragmatism and ease of understanding above theoretical perfection.
2.2 HOW NEAR WORKS?NEAR’s platform provides a community-operated cloud infrastructure for deploying and running decentralized applications. It combines the features of a decentralized database with others of a serverless compute platform. The token, which allows this platform to run also, enables applications built on top of it to interact with each other in new ways. Together, these features allow developers to create censorship resistant back-ends for applications that deal with high stakes data like money, identity, assets, and open-state components, which interact seamlessly with each other. These application back-ends and components are called “smart contracts,” though we will often refer to these all as simply “applications” here.
The infrastructure, which makes up this cloud, is created from a potentially infinite number of “nodes” run by individuals around the world who offer portions of their CPU and hard drive space — whether on their laptops or more professionally deployed servers. Developers write smart contracts and deploy them to this cloud as if they were deploying to a single server, which is a process that feels very similar to how applications are deployed to existing centralized clouds.
Once the developer has deployed an application, called a “smart contract”, and marked it unchangeable (“immutable”), the application will now run for as long as at least a handful of members of the NEAR community continue to exist. When end users interact with that deployed application, they will generally do so through a familiar web or mobile interface just like any one of a million apps today.
In the central cloud hosted by some companies today like: Amazon or Google, developers pay for their apps every month based on the amount of usage needed, for example based on the number of requests created by users visiting their webpages. The NEAR platform similarly requires that either users or developers provide compensation for their usage to the community operators of this infrastructure. Like today’s cloud infrastructure, NEAR prices usage based on easy to understand metrics that aren’t heavily influenced by factors like system congestion. Such factors make it very complicated for developers on alternative blockchain-based systems today.
In the centralized cloud, the controlling corporation makes decisions unilaterally. NEAR community-run cloud is decentralized so updates must ultimately be accepted by a sufficient quorum of the network participants. Updates about its future are generated from the community and subject to an inclusive governance process, which balances efficiency and security.
In order to ensure that the operators of nodes — who are anonymous and potentially even malicious — run the code with good behavior, they participate in a staking process called “Proof of Stake”. In this process, they willingly put a portion of value at risk as a sort of deposit, which they will forfeit if it is proven that they have operated improperly.
2.2.1 Elements of the NEAR’s PlatformThe NEAR platform is made up of many separate elements. Some of these are native to the platform itself while others are used in conjunction with or on top of it.
1. THE NEAR TOKEN
NEAR token is the fundamental native asset of the NEAR ecosystem and its functionality is enabled for all accounts. Each token is a unique digital asset similar to Ether, which can be used to:
a) Pay the system for processing transactions and storing data.
b) Run a validating node as part of the network by participating in the staking process.
c) Help determine how network resources are allocated and where its future technical direction will go by participating in governance processes.
The NEAR token enables the economic coordination of all participants who operate the network plus it enables new behaviors among the applications which are built on top of that network.
2. OTHER DIGITAL ASSETS
The platform is designed to easily store unique digital assets, which may include, but aren’t limited to:
The core platform, which is made up of the cloud of community-operated nodes, is the most basic piece of infrastructure provided. Developers can permissionlessly deploy smart contracts to this cloud and users can permissionlessly use the applications they power. Applications, which could range from consumer-facing games to digital currencies, can store their state (data) securely on the platform. This is conceptually similar to the Ethereum platform.
Operations that require an account, network use, or storage at the top of the platform require payment to the platform in the form of transaction fees that the platform then distributes to its community from the authentication contract. These operations could include creating new accounts, publishing new contracts, implementing code by contract and storing or modifying data by contract.
As long as the rules of the protocol are followed, any independent developer can write software, which interfaces with it (for example, by submitting transactions, creating accounts or even running a new node client) without asking for anyone’s permission first.
4. THE NEAR DEVELOPMENT SUITE
Set of tools and reference implementations created to facilitate its use by those developers and end users who prefer them. These tools include:
3. ECONOMICPrimarily economic forces drive the ecosystem, which makes up the NEAR platform. This economy creates the incentives, which allow participants permissionlessly organize to drive the platform’s key functions while creating strong disincentives for undesirable, irresponsible or malicious behavior. In order for the platform to be effective, these incentives need to exist both in the short term and in the long term.
The NEAR platform is a market among participants interested in two aspects:
3.1 NEAR ECONOMY DESIGN PRINCIPLESNEAR’s overall system design principles are used to inform its economic design according to the following interpretations:
1. Usability: End users and developers should have predictable and consistent pricing for their usage of the network. Users should never lose data forever.
2. Scalability: The platform should scale at economically justified thresholds.
3. Simplicity: The design of each of the system’s components should be as simple as possible in order to achieve their primary purpose.
4. Sustainable Decentralization: The barrier for participation in the platform as a validating node should be set as low as possible in order to bring a wide range of participants. Over time, their participation should not drive wealth and control into the hands of a small number. Individual transactions made far in the future must be at least as secure as those made today in order to safeguard the value they modify.
3.2 ECONOMIC OVERVIEWThe NEAR economy is optimized to provide developers and end users with the easiest possible experience while still providing proper incentives for network security and ecosystem development.
Summary of the key ideas that drive the system:
Founded in 2014, after 6 years of R & D as well as its expansion, and after nearly a year of extensive testing and preparation, IPFS (Interplanetary File System) was officially launched on the afternoon of October 15, 2020, UTC time. 12 hours after the mainnet went online, Its token price fluctuated between 50~70 USD/FIL. However, panic and pessimism began to spread between the IPFS community and FIL token holders. Based on the total amount of FIL (2 billion) and the unit price of 50 US dollars estimation, its market value has exceeded 100 billion US dollars, second only to BTC. As such a mega valued IPFS/FIL went online, if there is no enough application to support, the selling pressure after the FIL is gradually unlocked will become huge. According to calculations, on the first day of the mainnet launch, there will be 239,000 FILs to be sold. Assuming that the unit price is 30 USD, the released circulation will be 8 million USD. Assuming the unit price remains unchanged, the market will usher in a similar value on the 10th day. With a release amount of 15 million USD, it is very likely that the corresponding token price can be supported.submitted by Hayley_HOP to u/Hayley_HOP [link] [comments]
IPFS is a network transmission protocol designed to create persistent and distributed storage and sharing of files. In terms of its current active projects and companies, IPFS has added more than 5 billion files, involving multiple industries, and there are also many blockchain companies using this technology. When the IPFS mainnet and its Filecoin goes online, the market value will be based on the applications brought by the IPFS network. After Bitcoin and Ethereum, Filecoin is an upstart in the blockchain industry with a revolutionary technological breakthrough. The market predicts that Filecoin’s market value will surpass Bitcoin. Now let us analyze this project together that was given high hopes:
IPFS major features and disadvantages
The basic application of IPFS, Filecoin’s financial attributes and its incentive mechanism make it a very exciting global collaborative open source project. On this basis, the data of all mankind is stored in the IPFS network, and no one can tamper with it.
This magnificent scene provides at least three values for us:
What is HOP
The HOP protocol provides a decentralized and completely anonymous traffic service for people all over the world based on block chain. HOP combines P2P network transmission and block chain technology to establish a block chain micro-payment protocol based on the block chain transmission encryption protocol between P2P network bandwidth contributors and bandwidth users, and merge it into traffic mining. In the mining pool side, the whole protocol is built on the main network, which has Micro Payment and mining functions. In addition, HOP also supports traffic mining of ERC20 in any currency. So far, HOP is the only protocol that combines the above functions and is officially available in commercial application. It can provide terminal nodes for secure access to decentralized networks.
HOP features and comparison with IPFS
HOP and IPFS have certain similarities. The following table is a comparison of the two projects in terms of technology and application characteristics:
Why HOP might be a phenomenal project in the future
Compared with the disadvantages of IPFS which are not supporting for hot data storage, low storage efficiency, low disaster tolerance and the high threshold of providing storage capacity, The advantages of HOP are summarized as follows:
At present, most of the participants of HOP are top tier tech specialists, famous investors and politicians with global vision. We believe that projects like HOP, due to the open source and far-sighted technical foundation, which can not only achieve internal self-consistent circulation, but also integrate well with external ecology. Just as water conservancy is invisible, HOP has unlimited inclusiveness and scalability, and has a strong platform-level vitality!
We are looking forward to the accumulation of HOP, bringing a revolution in technology and applications to the blockchain and the practical universe!

Submitted for consideration to The Great Reddit Scaling Bake-Off
Baked by the pastry chefs at Offchain Labs
Please send questions or comments to [[email protected] ](mailto:[email protected])
We're excited to submit Arbitrum Rollup for consideration to The Great Reddit Scaling Bake-Off. Arbitrum Rollup is the only Ethereum scaling solution that supports arbitrary smart contracts without compromising on Ethereum's security or adding points of centralization. For Reddit, this means that Arbitrum can not only scale the minting and transfer of Community Points, but it can foster a creative ecosystem built around Reddit Community Points enabling points to be used in a wide variety of third party applications. That's right -- you can have your cake and eat it too!
Arbitrum Rollup isn't just Ethereum-style. Its Layer 2 transactions are byte-for-byte identical to Ethereum, which means Ethereum users can continue to use their existing addresses and wallets, and Ethereum developers can continue to use their favorite toolchains and development environments out-of-the-box with Arbitrum. Coupling Arbitrum’s tooling-compatibility with its trustless asset interoperability, Reddit not only can scale but can onboard the entire Ethereum community at no cost by giving them the same experience they already know and love (well, certainly know).
To benchmark how Arbitrum can scale Reddit Community Points, we launched the Reddit contracts on an Arbitrum Rollup chain. Since Arbitrum provides full Solidity support, we didn't have to rewrite the Reddit contracts or try to mimic their functionality using an unfamiliar paradigm. Nope, none of that. We launched the Reddit contracts unmodified on Arbitrum Rollup complete with support for minting and distributing points. Like every Arbitrum Rollup chain, the chain included a bridge interface in which users can transfer Community Points or any other asset between the L1 and L2 chains. Arbitrum Rollup chains also support dynamic contract loading, which would allow third-party developers to launch custom ecosystem apps that integrate with Community Points on the very same chain that runs the Reddit contracts.
1.1 Why Ethereum
Perhaps the most exciting benefit of distributing Community Points using a blockchain is the ability to seamlessly port points to other applications and use them in a wide variety of contexts. Applications may include simple transfers such as a restaurant that allows Redditors to spend points on drinks. Or it may include complex smart contracts -- such as placing Community Points as a wager for a multiparty game or as collateral in a financial contract.
The common denominator between all of the fun uses of Reddit points is that it needs a thriving ecosystem of both users and developers, and the Ethereum blockchain is perhaps the only smart contract platform with significant adoption today. While many Layer 1 blockchains boast lower cost or higher throughput than the Ethereum blockchain, more often than not, these attributes mask the reality of little usage, weaker security, or both.
Perhaps another platform with significant usage will rise in the future. But today, Ethereum captures the mindshare of the blockchain community, and for Community Points to provide the most utility, the Ethereum blockchain is the natural choice.
1.2 Why Arbitrum
While Ethereum's ecosystem is unmatched, the reality is that fees are high and capacity is too low to support the scale of Reddit Community Points. Enter Arbitrum. Arbitrum Rollup provides all of the ecosystem benefits of Ethereum, but with orders of magnitude more capacity and at a fraction of the cost of native Ethereum smart contracts. And most of all, we don't change the experience from users. They continue to use the same wallets, addresses, languages, and tools.
Arbitrum Rollup is not the only solution that can scale payments, but it is the only developed solution that can scale both payments and arbitrary smart contracts trustlessly, which means that third party users can build highly scalable add-on apps that can be used without withdrawing money from the Rollup chain. If you believe that Reddit users will want to use their Community Points in smart contracts--and we believe they will--then it makes the most sense to choose a single scaling solution that can support the entire ecosystem, eliminating friction for users.
We view being able to run smart contracts in the same scaling solution as fundamentally critical since if there's significant demand in running smart contracts from Reddit's ecosystem, this would be a load on Ethereum and would itself require a scaling solution. Moreover, having different scaling solutions for the minting/distribution/spending of points and for third party apps would be burdensome for users as they'd have to constantly shuffle their Points back and forth.
2. Arbitrum at a glance
Arbitrum Rollup has a unique value proposition as it offers a combination of features that no other scaling solution achieves. Here we highlight its core attributes.
Decentralized. Arbitrum Rollup is as decentralized as Ethereum. Unlike some other Layer 2 scaling projects, Arbitrum Rollup doesn't have any centralized components or centralized operators who can censor users or delay transactions. Even in non-custodial systems, centralized components provide a risk as the operators are generally incentivized to increase their profit by extracting rent from users often in ways that severely degrade user experience. Even if centralized operators are altruistic, centralized components are subject to hacking, coercion, and potential liability.
Massive Scaling. Arbitrum achieves order of magnitude scaling over Ethereum's L1 smart contracts. Our software currently supports 453 transactions-per-second for basic transactions (at 1616 Ethereum gas per tx). We have a lot of room left to optimize (e.g. aggregating signatures), and over the next several months capacity will increase significantly. As described in detail below, Arbitrum can easily support and surpass Reddit's anticipated initial load, and its capacity will continue to improve as Reddit's capacity needs grow.
Low cost. The cost of running Arbitrum Rollup is quite low compared to L1 Ethereum and other scaling solutions such as those based on zero-knowledge proofs. Layer 2 fees are low, fixed, and predictable and should not be overly burdensome for Reddit to cover. Nobody needs to use special equipment or high-end machines. Arbitrum requires validators, which is a permissionless role that can be run on any reasonable on-line machine. Although anybody can act as a validator, in order to protect against a “tragedy of the commons” and make sure reputable validators are participating, we support a notion of “invited validators” that are compensated for their costs. In general, users pay (low) fees to cover the invited validators’ costs, but we imagine that Reddit may cover this cost for its users. See more on the costs and validator options below.
Ethereum Developer Experience. Not only does Arbitrum support EVM smart contracts, but the developer experience is identical to that of L1 Ethereum contracts and fully compatible with Ethereum tooling. Developers can port existing Solidity apps or write new ones using their favorite and familiar toolchains (e.g. Truffle, Buidler). There are no new languages or coding paradigms to learn.
Ethereum wallet compatibility. Just as in Ethereum, Arbitrum users need only hold keys, but do not have to store any coin history or additional data to protect or access their funds. Since Arbitrum transactions are semantically identical to Ethereum L1 transactions, existing Ethereum users can use their existing Ethereum keys with their existing wallet software such as Metamask.
Token interoperability. Users can easily transfer their ETH, ERC-20 and ERC-721 tokens between Ethereum and the Arbitrum Rollup chain. As we explain in detail below, it is possible to mint tokens in L2 that can subsequently be withdrawn and recognized by the L1 token contract.
Fast finality. Transactions complete with the same finality time as Ethereum L1 (and it's possible to get faster finality guarantees by trading away trust assumptions; see the Arbitrum Rollup whitepaper for details).
Non-custodial. Arbitrum Rollup is a non-custodial scaling solution, so users control their funds/points and neither Reddit nor anyone else can ever access or revoke points held by users.
Censorship Resistant. Since it's completely decentralized, and the Arbitrum protocol guarantees progress trustlessly, Arbitrum Rollup is just as censorship-proof as Ethereum.
Block explorer. The Arbitrum Rollup block explorer allows users to view and analyze transactions on the Rollup chain.
Although this is a bake-off, we're not going to sugar coat anything. Arbitrum Rollup, like any Optimistic Rollup protocol, does have one limitation, and that's the delay on withdrawals.
As for the concrete length of the delay, we've done a good deal of internal modeling and have blogged about this as well. Our current modeling suggests a 3-hour delay is sufficient (but as discussed in the linked post there is a tradeoff space between the length of the challenge period and the size of the validators’ deposit).
Note that this doesn't mean that the chain is delayed for three hours. Arbitrum Rollup supports pipelining of execution, which means that validators can keep building new states even while previous ones are “in the pipeline” for confirmation. As the challenge delays expire for each update, a new state will be confirmed (read more about this here).
So activity and progress on the chain are not delayed by the challenge period. The only thing that's delayed is the consummation of withdrawals. Recall though that any single honest validator knows immediately (at the speed of L1 finality) which state updates are correct and can guarantee that they will eventually be confirmed, so once a valid withdrawal has been requested on-chain, every honest party knows that the withdrawal will definitely happen. There's a natural place here for a liquidity market in which a validator (or someone who trusts a validator) can provide withdrawal loans for a small interest fee. This is a no-risk business for them as they know which withdrawals will be confirmed (and can force their confirmation trustlessly no matter what anyone else does) but are just waiting for on-chain finality.
3. The recipe: How Arbitrum Rollup works

4. Developer docs and APIs
For full details about how to set up and interact with an Arbitrum Rollup chain or validator, please refer to our developer docs, which can be found at https://developer.offchainlabs.com/.
Note that the Arbitrum version described on that site is older and will soon be replaced by the version we are entering in Reddit Bake-Off, which is still undergoing internal testing before public release.
5. Who are the validators?
As with any Layer 2 protocol, advancing the protocol correctly requires at least one validator (sometimes called block producers) that is honest and available. A natural question is: who are the validators?
Recall that the validator set for an Arbitrum chain is open and permissionless; anyone can start or stop validating at will. (A useful analogy is to full nodes on an L1 chain.) But we understand that even though anyone can participate, Reddit may want to guarantee that highly reputable nodes are validating their chain. Reddit may choose to validate the chain themselves and/or hire third-party validators.To this end, we have begun building a marketplace for validator-for-hire services so that dapp developers can outsource validation services to reputable nodes with high up-time. We've announced a partnership in which Chainlink nodes will provide Arbitrum validation services, and we expect to announce more partnerships shortly with other blockchain infrastructure providers.
Although there is no requirement that validators are paid, Arbitrum’s economic model tracks validators’ costs (e.g. amount of computation and storage) and can charge small fees on user transactions, using a gas-type system, to cover those costs. Alternatively, a single party such as Reddit can agree to cover the costs of invited validators.
6. Reddit Contract Support
Since Arbitrum contracts and transactions are byte-for-byte compatible with Ethereum, supporting the Reddit contracts is as simple as launching them on an Arbitrum chain.
Minting. Arbitrum Rollup supports hybrid L1/L2 tokens which can be minted in L2 and then withdrawn onto the L1. An L1 contract at address A can make a special call to the EthBridge which deploys a "buddy contract" to the same address A on an Arbitrum chain. Since it's deployed at the same address, users can know that the L2 contract is the authorized "buddy" of the L1 contract on the Arbitrum chain.
For minting, the L1 contract is a standard ERC-20 contract which mints and burns tokens when requested by the L2 contract. It is paired with an ERC-20 contract in L2 which mints tokens based on whatever programmer provided minting facility is desired and burns tokens when they are withdrawn from the rollup chain. Given this base infrastructure, Arbitrum can support any smart contract based method for minting tokens in L2, and indeed we directly support Reddit's signature/claim based minting in L2.
Batch minting. What's better than a mint cookie? A whole batch! In addition to supporting Reddit’s current minting/claiming scheme, we built a second minting design, which we believe outperforms the signature/claim system in many scenarios.
In the current system, Reddit periodically issues signed statements to users, who then take those statements to the blockchain to claim their tokens. An alternative approach would have Reddit directly submit the list of users/amounts to the blockchain and distribute the tokens to the users without the signature/claim process.
To optimize the cost efficiency of this approach, we designed an application-specific compression scheme to minimize the size of the batch distribution list. We analyzed the data from Reddit's previous distributions and found that the data is highly compressible since token amounts are small and repeated, and addresses appear multiple times. Our function groups transactions by size, and replaces previously-seen addresses with a shorter index value. We wrote client code to compress the data, wrote a Solidity decompressing function, and integrated that function into Reddit’s contract running on Arbitrum.
When we ran the compression function on the previous Reddit distribution data, we found that we could compress batched minting data down to to 11.8 bytes per minting event (averaged over a 6-month trace of Reddit’s historical token grants)compared with roughly 174 bytes of on-chain data needed for the signature claim approach to minting (roughly 43 for an RLP-encoded null transaction + 65 for Reddit's signature + 65 for the user's signature + roughly 8 for the number of Points) .
The relative benefit of the two approaches with respect to on-chain call data cost depends on the percentage of users that will actually claim their tokens on chain. With the above figures, batch minting will be cheaper if roughly 5% of users redeem their claims. We stress that our compression scheme is not Arbitrum-specific and would be beneficial in any general-purpose smart contract platform.
8. Benchmarks and costs
In this section, we give the full costs of operating the Reddit contracts on an Arbitrum Rollup chain including the L1 gas costs for the Rollup chain, the costs of computation and storage for the L2 validators as well as the capital lockup requirements for staking.
Arbitrum Rollup is still on testnet, so we did not run mainnet benchmarks. Instead, we measured the L1 gas cost and L2 workload for Reddit operations on Arbitrum and calculated the total cost assuming current Ethereum gas prices. As noted below in detail, our measurements do not assume that Arbitrum is consuming the entire capacity of Ethereum. We will present the details of our model now, but for full transparency you can also play around with it yourself and adjust the parameters, by copying the spreadsheet found here.
Our cost model is based on measurements of Reddit’s contracts, running unmodified (except for the addition of a batch minting function) on Arbitrum Rollup on top of Ethereum.
On the distribution of transactions and frequency of assertions. Reddit's instructions specify the following minimum parameters that submissions should support:
Over a 5 day period, your scaling PoC should be able to handle:
We note that assuming that there are only 300,000 transactions that arrive uniformly over the 5 day period will make our benchmark numbers lower, but we believe that this will reflect the true cost of running the system. To see why, say that batches are submitted every five minutes (20 L1 blocks) and there's a fixed overhead of c bytes of calldata per batch, the cost of which will get amortized over all transactions executed in that batch. Assume that each individual transaction adds a marginal cost of t. Lastly assume the capacity of the scaling system is high enough that it can support all of Reddit's 300,000 transactions within a single 20-block batch (i.e. that there is more than c + 300,000*t byes of calldata available in 20 blocks).
Consider what happens if c, the per-batch overhead, is large (which it is in some systems, but not in Arbitrum). In the scenario that transactions actually arrive at the system's capacity and each batch is full, then c gets amortized over 300,000 transactions. But if we assume that the system is not running at capacity--and only receives 300,000 transactions arriving uniformly over 5 days-- then each 20-block assertion will contain about 200 transactions, and thus each transaction will pay a nontrivial cost due to c.
We are aware that other proposals presented scaling numbers assuming that 300,000 transactions arrived at maximum capacity and was executed in a single mega-transaction, but according to our estimates, for at least one such report, this led to a reported gas price that was 2-3 orders of magnitude lower than it would have been assuming uniform arrival. We make more realistic batching assumptions, and we believe Arbitrum compares well when batch sizes are realistic.
Our model. Our cost model includes several sources of cost:
Our model also shows that Arbitrum can scale to workloads much larger than Reddit’s nominal workload, without exhausting L1 or L2 resources. The scaling bottleneck will ultimately be calldata on the L1 chain. We believe that cost could be reduced substantially if necessary by clever encoding of data. (In our design any compression / decompression of L2 transaction calldata would be done by client software and L2 programs, never by an L1 contract.)
9. Status of Arbitrum Rollup
Arbitrum Rollup is live on Ethereum testnet. All of the code written to date including everything included in the Reddit demo is open source and permissively licensed under the Apache V2 license. The first testnet version of Arbitrum Rollup was released on testnet in February. Our current internal version, which we used to benchmark the Reddit contracts, will be released soon and will be a major upgrade.
Both the Arbitrum design as well as the implementation are heavily audited by independent third parties. The Arbitrum academic paper was published at USENIX Security, a top-tier peer-reviewed academic venue. For the Arbitrum software, we have engaged Trail of Bits for a security audit, which is currently ongoing, and we are committed to have a clean report before launching on Ethereum mainnet.
10. Reddit Universe Arbitrum Rollup Chain
The benchmarks described in this document were all measured using the latest internal build of our software. When we release the new software upgrade publicly we will launch a Reddit Universe Arbitrum Rollup chain as a public demo, which will contain the Reddit contracts as well as a Uniswap instance and a Connext Hub, demonstrating how Community Points can be integrated into third party apps. We will also allow members of the public to dynamically launch ecosystem contracts. We at Offchain Labs will cover the validating costs for the Reddit Universe public demo.
If the folks at Reddit would like to evaluate our software prior to our public demo, please email us at [email protected] and we'd be more than happy to provide early access.
11. Even more scaling: Arbitrum Sidechains
Rollups are an excellent approach to scaling, and we are excited about Arbitrum Rollup which far surpasses Reddit's scaling needs. But looking forward to Reddit's eventual goal of supporting hundreds of millions of users, there will likely come a time when Reddit needs more scaling than any Rollup protocol can provide.
While Rollups greatly reduce costs, they don't break the linear barrier. That is, all transactions have an on-chain footprint (because all calldata must be posted on-chain), albeit a far smaller one than on native Ethereum, and the L1 limitations end up being the bottleneck for capacity and cost. Since Ethereum has limited capacity, this linear use of on-chain resources means that costs will eventually increase superlinearly with traffic.
The good news is that we at Offchain Labs have a solution in our roadmap that can satisfy this extreme-scaling setting as well: Arbitrum AnyTrust Sidechains. Arbitrum Sidechains are similar to Arbitrum Rollup, but deviate in that they name a permissioned set of validators. When a chain’s validators agree off-chain, they can greatly reduce the on-chain footprint of the protocol and require almost no data to be put on-chain. When validators can't reach unanimous agreement off-chain, the protocol reverts to Arbitrum Rollup. Technically, Arbitrum Sidechains can be viewed as a hybrid between state channels and Rollup, switching back and forth as necessary, and combining the performance and cost that state channels can achieve in the optimistic case, with the robustness of Rollup in other cases. The core technical challenge is how to switch seamlessly between modes and how to guarantee that security is maintained throughout.
Arbitrum Sidechains break through this linear barrier, while still maintaining a high level of security and decentralization. Arbitrum Sidechains provide the AnyTrust guarantee, which says that as long as any one validator is honest and available (even if you don't know which one will be), the L2 chain is guaranteed to execute correctly according to its code and guaranteed to make progress. Unlike in a state channel, offchain progress does not require unanimous consent, and liveness is preserved as long as there is a single honest validator.
Note that the trust model for Arbitrum Sidechains is much stronger than for typical BFT-style chains which introduce a consensus "voting" protocols among a small permissioned group of validators. BFT-based protocols require a supermajority (more than 2/3) of validators to agree. In Arbitrum Sidechains, by contrast, all you need is a single honest validator to achieve guaranteed correctness and progress. Notice that in Arbitrum adding validators strictly increases security since the AnyTrust guarantee provides correctness as long as any one validator is honest and available. By contrast, in BFT-style protocols, adding nodes can be dangerous as a coalition of dishonest nodes can break the protocol.
Like Arbitrum Rollup, the developer and user experiences for Arbitrum Sidechains will be identical to that of Ethereum. Reddit would be able to choose a large and diverse set of validators, and all that they would need to guarantee to break through the scaling barrier is that a single one of them will remain honest.
We hope to have Arbitrum Sidechains in production in early 2021, and thus when Reddit reaches the scale that surpasses the capacity of Rollups, Arbitrum Sidechains will be waiting and ready to help.
While the idea to switch between channels and Rollup to get the best of both worlds is conceptually simple, getting the details right and making sure that the switch does not introduce any attack vectors is highly non-trivial and has been the subject of years of our research (indeed, we were working on this design for years before the term Rollup was even coined).
12. How Arbitrum compares
We include a comparison to several other categories as well as specific projects when appropriate. and explain why we believe that Arbitrum is best suited for Reddit's purposes. We focus our attention on other Ethereum projects.
Payment only Rollups. Compared to Arbitrum Rollup, ZK-Rollups and other Rollups that only support token transfers have several disadvantages:
While it's ultimately up to the judges’ palate, we believe that Arbitrum Rollup is the bakeoff choice that Reddit kneads. We far surpass Reddit's specified workload requirement at present, have much room to optimize Arbitrum Rollup in the near term, and have a clear path to get Reddit to hundreds of millions of users. Furthermore, we are the only project that gives developers and users the identical interface as the Ethereum blockchain and is fully interoperable and tooling-compatible, and we do this all without any new trust assumptions or centralized components.
But no matter how the cookie crumbles, we're glad to have participated in this bake-off and we thank you for your consideration.

Financial risk management is one of the most controversial topics in trading. Traders want to reduce the risk and potential loss, but on the other hand, these traders also want at the same time to get the best profits. It is known that in order to obtain greater returns, you also need to take greater risks.
Some may consider trading an entertaining and difficult pastime, but everyone should be aware that the most important aspect of trading is risk management.
What are the different risk management techniques used in trading?Long-term trading
Stock market traders use historical data to make long-term strategic business decisions. The long-term cryptocurrency strategy depends on current activity, and you will be more inclined towards hopeful information rather than reliable information and more suitable for cryptocurrencies.
Short term trading
Short-term traders benefit from the volatile cryptocurrency market by using swing trading when the price differs in short bursts of movement.
Technical analysis of cryptocurrencies requires research into project that affect the market based on price and volume data available through analytical technology.
Traders often look to blogs and information sites and study the whitepaper for cryptocurrencies or cryptocurrency community forums.
Why should you stick to risk management?You can get a series of successful deals based on good luck. You can also get a series of bad deals that depend on luck and feel.
It even happens to successful, experienced professional traders that they lose 10 trades in a row. Without risk management, this could result in your capital loss and final exit. The most important goal in trading is to stay in the market and preserve your capital. As long as you are in the market, you can recoup your losses.
If you lose 10% of your capital, this means that you must make a profit of 11.1%. If your budget is $ 1,000 and you lose $ 100 ( ~ to 10%), you’ll have $ 900. $ 100 is 11.1% of that.
This means that losses hurt more than profits of the same size. This becomes worse with more losses. If you lose 50% of your capital, you must double your money to offset the loss.
The new trader’s rule for managing at most risk is 1% of the capital for each trade. If you lose 10 deals in a row (which is unlikely) and lose 1% each time, how much do you have left? Still 90%.
If you risk 2%, what remains for you after losing 10 recurring deals is only 81% of the capital. You have to make 11% or 23% profit to make up for it. Even if you lose 100 deals in a row with a 1% risk management plan in hand, you still have 37%.
A seasoned trader may use 2% occasionally. A trader who risks 10% disappears quickly.
You might be wondering, if I decide to follow risk management with just 1% in the deal, does this mean that I can only invest 1% of the capital for each transaction? No. This is the ratio for determining the maximum acceptance of a loss from a single trade.
I assume you know your total capital, no matter if it is $ 100 or $ 1 billion. The main point is to have a specific budget available. Do not use borrowed money, which you have to repay in a deadline. Do not use money you need in the future. If you are emotionally attached to this money, these emotions will make you feel stressed. You want to be a successful trader and not an emotional gambler.
The next step is to find a deal. It does not matter if you do this daily and trade specific currencies or not. You have tools like fundamental and technical analysis to research deals. Immediately before entering into a trade, there is a basic calculation that must be performed:
Determine the entry price, stop loss and the amount of risk.
Well, the risk is easy. We already know that we will choose 1%.
The entry price is also easy. It could be the current market price or the limit you set for your order.
Now, stop loss: it is necessary to know and set the stop loss before entering a trade. Another rule is that you are not allowed to adjust your stop loss afterward to accept more losses.
How to determine the stop loss? Technical analysis is the only method available regardless of the random selection of something. Perhaps you will use something like “beyond the next support level (or resistance)” or “the other side of the trend line we just broke”.
Now we have the four components of risk management: budget size, entry price, stop-loss and risk-taking. The time to use the calculator.
The size of the deal
Now to find out how much money you are allowed to invest in this deal.
Transaction Size = (Risk Size * Budget) / (Entry Price — Stop Loss)
For example: If you have a budget $ 1,000 and want to buy bitcoin for $ 2,300 with a stop loss $ 2,200 and a risk 1%, then this means: The deal size is (1% * $ 1,000) / ($ 2,300 — $ 2,200) ) = $ 10 / $ 100 = 0.1.
So in this example you are allowed to buy 0.1 Bitcoin units for this trade.
You must make this account before every trade! Even if you do, you will encounter errors sometimes, but risk management will help you to preserve your capital. Courage will shout at you to take greater risks, because you are very sure of your prediction. But always remember, to succeed you must stick to your stop loss and strategy.
Before entering into a position, you must also have a target price in mind for sale. The risk must be doubled. If you risk 1% of your capital, the potential profit must be 2–3% of your capital. If the goal for profit is equal to stopping the loss, you must stay away from trading and ignore this deal.
This does not mean that you will always reach or lose your goal. You are allowed to manually track stop loss or exit early. However, the goal should be possible given the volatility of the market you are in.
Level of risk
Well, I got away from the plan and ignored your strategy. The deal entered without due diligence. whatever. How much risk did you just take?
You know your budget, entry price and deal size. You must quickly define the next stop loss. How much risk?
Risk = (Trade Size * (Entry Point — Stop Loss)) / Budget
For example, I bought 0.3 bitcoin at a price of $ 2,500 with a budget of $ 1,000. Stop loss is $ 2345. This means that the risk is (0.3 * 155 dollars) / 1000 dollars = 4.64%.
Now for some good things that can’t be used practically, however, the concepts are sound. Why the reader may ask 1% risk? Is it just a rule? Is there an ideal ratio? In theory, yes there is. We can use the Kelly standard. The formula is simple:
Risk = p-((1-p)/r
Getting those variables P and R is difficult. You have to know your profit rate, which is the number of times your goals are reached. You also need a profit-to-loss ratio, which is the average profit per trade.
For example, if you earn 47% of the time and 117% of your average capital, then the ideal risk is 1.7%.
In practice you don’t really know this specifically or variables p and r, so I recommend sticking to 1% as the basis for risk management.
Risk Management Tips for Cryptocurrency Investment1. You should never risk more than you can afford to lose.
However, this error is very common, especially among Crypto traders who are just starting out. The Crypto market is very difficult to predict, so traders who want to invest more than they can actually put themselves at risk of market and losing their money.
2. Don’t trade by all of your capital at same time.
Anything can affect the Crypto market. The smallest news can affect the price of a particular currency in a negative or positive way. Instead of trade with everything you own”, it is better to follow a more moderate path and trade reasonable amounts of your capital.
3. Improve your risk management performance
Fortunately, there are several ways to help avoiding these mistakes and avoid loss. You must have a well-tested trading plan that includes all the details of managing financial risk in Crypto. The trading plan should be practical — and you should be able to follow its steps easily. Experts recommend that it is better to focus on high-probability deals.

4. Control your emotions and risk management
As a Crypto trader, you need to be able to control your feelings and emotions towards your open, future, and closed positions as well! If you cannot control your feelings, you will not be able to reach a position where you can make the profits you want to trade. Market sentiment can often trap traders in volatile positions in the market. This is one of the most common market risk for Crypto trading. Those with stubborn nature tend not to do well in the Crypto market.
These types of traders tend to wait too long to exit the trade. When a trader realizes his mistake, he must leave the market as soon as possible, to take the least possible loss.

6. Important tips for developing a risk management plan model
Below is a series of simple tips that you can consider and include in the financial risk management plan model when trading Crypto, which may help you reduce trading losses associated with market risks:
1. Stop losses
Trading without a stop loss is like driving a car without braking at full speed — it won’t end well. Likewise, once your stop loss is set, you should never lower it. There is no point in having a safety net in place if you are not going to use it properly.
The goal of stopping a loss is to limit the size of the potential loss in order to be able to in-crease your total profits, and what needs to be done on the other side is to set profit-taking orders as well!
2. Do not link all your investments in one place
This applies to all types of investment, and Crypto is no exception. Crypto should be part of your portfolio, but not complete it. Another way that you can expand it is to invest or trade more than one crypto coin.
3. The general trend is your companion
You may have made the decision to be a long-term trader, with plans to keep these deals for an extended period of time. However, regardless of the deal you ultimately decided to take, you should not resist current market trends or movements. There will always be strong players in the market, and the best way to keep up with them is to absorb such changes and follow the general trend, and change your strategies to reflect this.
4. Keep teaching yourself
The best way to learn the financial risk management system in Crypto and become an efficient and successful Crypto trader is to know how the market works. However, as we mentioned earlier, the market is constantly changing, so if you want to stay ahead of your game, you have to be always ready to learn new things and update yourself about market changes.
5. Use the plug-in
To advance in Crypto, you may want to use some trading software that can help you settle your choices. However, these systems are not ideal, so it is best to use them as a consulting tool, and something to refer to rather than use as a basis for making business decisions.
6. Limiting the use of leverage
It can be very tempting to use leverage to make big profits. However, this can make it easy for you to lose a huge portion of your capital, too. So do not support the use of giant leverage. All it takes is one quick change in market direction, and you can easily delete your entire trading account.
Crypto risk management is not difficult to understand and implement.

The hard part is having enough self-discipline to adhere to the rules of this risk management plan as the market moves against your positions.
