Not your keys, not your coins.

Every crypto holder must be familiar with this quote. The recent run on FTX, a top crypto exchange, due to the revelation of fund misappropriation once again reminded us of the fact that “not your keys, not your coins.” To this day, a large number of users and institutions still cannot withdraw their funds on FTX. Although many people would advise you to enhance asset security by adopting a cold wallet, but is it the perfect solution to the problems of asset management?



What are cold wallets?
In our previous article titled Must-know Concepts About Crypto Wallets, we mentioned that crypto wallets are tools used to store our private keys, and there are cold wallets and hot wallets depending on how the private key is stored.

Hot wallets, also known as online wallets, refer to wallets connected to the Internet. For instance, most web wallets, wallet extensions, and wallet apps are all hot wallets. Such wallets promise great ease of use, and we can transfer cryptos and use DApps on webpages and smartphones at any time.

Cold wallets, or offline wallets, are the opposite of hot wallets. They are wallets used without an internet connection. Without access to the Internet, they minimize the risks of hacking. Many crypto users think that cold wallets are just another name for hardware wallets, which isn’t true because, for instance, a wallet generated on a smartphone without an internet connection through ViaWallet is also a cold wallet. By the same token, generating the private key on an offline PC and copying that private key on paper also creates a cold wallet.

Should I choose cold wallets or hot wallets?
Many people go for cold wallets without doing much thinking because they believe that offline wallets are safer, but cold wallets are not designed for all scenarios. For instance, as the private key is not exposed to the Internet, users of a cold wallet must conduct internal, offline authentication through a special device or grant authorization via the offline signature function of an offline phone.

Such operations are troublesome, especially if you use DApps on a daily basis. As such, cold wallets can only meet the needs of long-term crypto holders who only trade cryptos once in a while. If you are a big crypto holder and frequently use DeFi or buy NFTs, a better choice is to store most cryptos in cold wallets while keeping part of liquid funds in hot wallets.

Choosing a safe and reliable hot wallet is also essential. As a decentralized wallet featuring multiple chains and cryptos, ViaWallet offers twofold protection with the security password and protects mnemonics via encrypted backups, which effectively keeps the private key and mnemonics safe and secure. For more information about ViaWallet’s security functions, please refer to ViaWallet: Keeping Your Cryptos Secure Through Multiple Layers of Protection.

Using wallets in safer ways
Adopting a suitable wallet is not a once-and-for-all solution. Although decentralized wallets such as ViaWallet help users mitigate risks through sound product design, as blockchain is inherently decentralized, such wallets offer full control of the assets to users themselves, which means that users must also adopt security measures to stay safe.

When using crypto wallets, be sure to remember the following tips:

1. You should always download the App from the official website, and do not download wallet applications from non-official websites;

2. Remember to make multiple offline back-ups of your private key or mnemonics, and do not disclose them to any third party or reveal such sensitive information on online platforms such as live chat software.

3. You’d better become more security-aware. For example, you can enhance your asset-protection measures by reading the relevant articles in ViaWallet Blog, which regularly releases security know-hows.

In the blockchain world, asset security is always the №1 priority. Although cold wallets are excellent tools for enhancing security, actual asset management is not that simple, and we can avoid potential asset losses by using crypto wallets in safer ways.

Since the outbreak of the COVID-19 pandemic in 2019, many large offline events around the world have been affected. For athletes, competing in venues without a live audience is less exciting. For sports fans, such restrictions are also disappointing. Like a derailed train headed toward the unknown, everything seems to have lost control. Meanwhile, it seems that the Qatar World Cup, which will soon kick off on November 20, might put an end to the present chaos, as it will be the first unrestricted offline large sports event in the world after the outbreak of the pandemic. The world seems to be trying to get back on the right track.

The World Cup is hosted every four years, and Qatar was awarded the right to host the 2022 FIFA World Cup back in 2010. This year’s World Cup is unique because Qatar is not only the smallest host country in history but also the first Islamic country in the world to host the World Cup. CoinEx will follow this football feast together with numerous investors and cheer for athletes.



The crypto market turned its attention to the Qatar World Cup a few months ago. To start with, fan tokens launched by different teams witnessed significant price swings. According to data provided by CoinEx, SANTOS, PORTO, LAZIO, and ALPINE have risen for two months in a row (August and September). Subsequently, famous football players like Neymar, Cristiano Ronaldo, and David Beckham have also issued their own NFTs. Apart from that, in September, FIFA also proposed to launch “FIFA+ Collect”, a football-themed NFT collection platform, on Algorand.

Right now, a growing number of companies are embracing cryptos and going beyond the limits of traditional business models. Committed to its original motivation of “Making Crypto Trading Easier”, CoinEx is also constantly shattering the restraints of conventional finance, thereby introducing crypto to more users worldwide. Such commitments echo the values championed by the FIFA World Cup. Through intense matches, the World Cup enables different cultures to collide and converge, thus fostering a fundamental driving force for peaceful global development.

As a crypto exchange that has been running for five years, CoinEx has spared no effort to provide the easiest and most convenient crypto trading services for global users. Through the constant improvement of coding and products, the exchange has attracted users through the most appealing charm of crypto trading.

Available in 15 languages, including English, Chinese, French, Spanish, Arabic, and Portuguese, CoinEx now supports 600+ crypto trading pairs and allows users to buy/sell cryptos with over 60 kinds of fiat currencies through 10 third-party service providers. The exchange has also built a versatile product range, covering spot trading, futures contracts, margin trading, financial services, AMM, and Dock. To date, CoinEx has provided easy and convenient crypto trading services for more than 3 million people in over 200 countries and regions around the world.



This December, CoinEx will celebrate its fifth anniversary. Every storm begins as a ruffle in the grass. In the past five years, CoinEx has stayed true to its original motivations and turned sophistication into ease of use. The exchange also incorporated the features of blockchain, such as inclusiveness and simplicity, into every aspect of its products to give people from all regions and cultures a window on the charm of crypto. Since its inception, the exchange has always practiced the principle of “Making Crypto Trading Easier”, and has built a strong track record with the suggestions and recognition from users.

Facing great changes unseen in a century, we are standing at the intersection of the new era. In the future, CoinEx will strive for constant improvement and embrace changes to prepare itself for the crypto era. As the exchange creates new records together with all users, CoinEx will provide first-rate services for more people around the world in the next five years as their gateway to the crypto world.

As it continues to track the 2022 Qatar World Cup, CoinEx will applaud each moment of excellence and cheer for all athletes who go beyond their limits to achieve their goals.

In Web 2.0 (the traditional Internet), websites acquire the data of their users and send it to centralized Internet companies. From a technical perspective, these companies can treat that data any way they see fit, and it is hard to prevent data leaks, despite the constraints of laws and regulations. For most users, keeping personal data private is a major challenge. Although we regard personal privacy as a major asset, existing infrastructures in cyberspace fail to ensure the safety of such assets. Moreover, when talking about the disruptive applications of Web 3.0 and the transformations it could bring, a major topic is that Web 3.0 can help users fully control their private information.

Although blockchain technology makes data more authentic and transparent, the level of data transparency enabled by blockchain fails to meet Web 3.0 users’ demand in certain scenarios. In the world of Web 3.0, users’ sensitive information, such as transaction/transfer records and on-chain activities, is easily accessible to anyone. Moreover, most Layer 1 public chains now suffer from lack of privacy.

As such, the appearance of privacy-preserving public chains fully meets the demand for privacy protection among Web 3.0 users. These chains provide users with privacy protection solutions, which allow them to selectively hide their sensitive information through technologies such as zero-knowledge proofs (ZKPs) and secure multi-party computation (MPC). Right now, the privacy segment is divided into four categories: privacy coins, privacy-preserving computation networks, privacy-preserving trading networks, and private applications. In particular, privacy coins appeared the earliest, which represents an early attempt to add privacy attributes to crypto. Typical privacy coins include Monero and Zcash. However, right now, a large proportion of privacy-preserving public chains focus on computation networks and trading networks. Speaking of privacy-preserving computation networks, we may think of PlatON and Oasis. As for privacy-preserving trading networks, there are a large number of new public chains, including Aleo, Anoma, and Aztec, among others. As the name implies, a privacy-preserving trading network keeps users’ transactions private and conceals their transaction data, which covers the identity of parties involved, date, amount, etc.

In this article, we will dive into two new public chains that offer privacy-preserving trading networks: Aleo and Aztec.

I. Aleo
1. Overview
Positioned as a privacy-preserving Layer 1 public chain, Aleo can now be regarded as a modular zero-knowledge platform for private applications that provides full-stack solutions.

Aleo strives to build a modular, compliant zero-knowledge platform for private applications, creating the ultimate toolkit for private applications. To achieve that, the chain leverages decentralized systems and zero-knowledge cryptography to protect user data on the web. At its core, Aleo offers users and application developers unbounded computation space and absolute privacy. With Aleo, users can access a world of personalized web services without giving up control of their private data. Applications built on Aleo can achieve absolute privacy. More specifically, they help users hide interaction details such as the parties involved, amount, and smart contracts, and will not disclose information unrelated to the present operation.

2. Team
Members of the Aleo team come from giant companies such as Google, Amazon, and Meta. The team also includes world-class cryptographers, engineers, and designers from celebrated institutions like UC Berkeley, New York University, and Cornell University. Howard Wu, one of the founders of Aleo, graduated from UC Berkeley with bachelor’s degrees in Computer Science and Mathematics. Howard worked as a Software Engineer at Google after graduating with an undergraduate degree, and then returned to UC Berkeley to complete his master’s degree. Since 2014, he has contributed code to crypto wallets, exchanges, ZCash, and Ethereum. In addition, Collin Chin, another member of the team, also graduated from UC Berkeley with a degree in CS and now heads the development of Aleo’s programming language Leo. Besides that, Aleo is backed by a strong lineup of institutional investors, including a16z, SoftBank, Tiger Global, etc.

3. Technology
Aleo uses ZKPs and an optimized version of PoSW, which is a variant of PoW, to avoid massive useless computation under PoW. This not only ensures sound privacy but also solves the problem of performance, which is the biggest challenge facing existing blockchains. According to its test data, the chain’s TPS has reached 10,000, though the actual performance is subject to testing after the mainnet launch. Aleo’s Layer 1 mainly functions as the data layer. Additionally, the network’s execution layer is off-chain, and the validation layer consists of Layer 1 validators on the network, which resembles ETH 2.0.



The fundamental technology of Aleo has three components: the ZEXE architecture, the Leo programming language, and zkCloud:

Zero Knowledge Execution (ZEXE): The ZEXE architecture is a specific zero-knowledge proof solution proposed by Aleo. ZEXE conducts offline computations first and then generates online transactions that prove the correctness of the computations without disclosing the details, which means that the transaction can be verified by anyone in a very short period of time. ZEXE also features programmability, allowing users to choose the information to be encrypted and determine the privacy settings.
Leo: Inspired by Rust, Leo is a functional, statically-typed programming language built for writing private applications. It can modularize the zk-snarks settings of the ZEXE consensus protocol, which allows any DApp running on Aleo to use zk-snarks, making app development easier. With Leo, developers can integrate ZKP into various web applications that protect the user’s privacy by making sure that no trace of personal data is left when the app is being used.
zkCloud: Proposed by Aleo, zkCloud is an off-chain, trustless computing environment, where programs are executed privately, securely, and cheaply, and with unlimited runtime. It enables programmatic interactions between shielded identities. Moreover, shielded identities interact directly (as in an asset transfer) or programmatically (through a smart contract). By moving this interaction off-chain, Aleo guarantees privacy and enables greater transaction throughput.
II. Aztec
1. Overview
Aiming to preserve the privacy of transactions, Aztec Network is a scalable, programmable Layer 2 privacy-preserving protocol based on ZK-Rollup. The network uses a solution called private rollup that’s similar to ZK-Rollup to encrypt and hide users’ confidential transactions. Aztec features two main functions: 1) privacy protection; 2) users can provide programmable contracts through Aztec to build fully private applications.

2. Team
Aztec is headquartered in London, UK. With strong technical capabilities, the core team of Aztec has brought many R&D breakthroughs to Layer 2 on Ethereum. Two of the three co-developers of Plonk, the underlying proof system of the network, are now on the team.

Aztec CEO Zac Williamson has a doctorate in Neutrino Physics from Oxford. He is a former physicist at the European Organization for Nuclear Research (CERN) and T2K Japan. Zac is also the co-creator of Plonk and founder of the Aztec Protocol.

Aztec CPO Joe Andrews graduated from Imperial College London and is the former CTO of Radish, a tech start-up based in Silicon Valley. Joe has rich experience in development.

Chief Scientist Ariel Gabizon has a doctorate in CS from the Weizmann Institute in Israel. He used to be a researcher and engineer at Zcash and is one of the inventors of Plonk.

Institutional investors behind Aztec include Paradigm, IOSG Ventures, Variant Fund, Nascent, Vitalik Buterin, etc.

3. Technology
The Aztec team invented Plonk, a general-purpose zk-snark technology, to provide ZKP support for privacy contracts. Users can run programmable privacy protection contracts in Plonk Rollup through Noir, its programming language, and develop applications according to different privacy needs and application scenarios.

Aztec follows an unspent transaction output (UTXO) model similar to that of Bitcoin, and each UTXO is called a Note, which records the changes in the state of each transaction. The note is the basic computation unit in Aztec. The values of a note are all encrypted, and the status of each note is recorded in the note registry. Suppose Alice has a $200 note in her account and transfers $100 to Bob. At this point, the $200 note is split into two $100 notes, one of which is owned by Alice and the other owned by Bob. For an account address, its entire balance is the sum of all UTXOs. Under such a bookkeeping model, whenever a user engages in a transaction, he/she is essentially burning one or multiple notes to generate one or multiple notes with the same value while transferring the ownership of some of the notes.



When conducting a transaction, users need to burn notes, generate notes that are of the same value, and then transfer the ownership of the corresponding notes. To conduct such a private transaction, users also have to generate privacy proofs locally. Then, 28 client proofs are aggregated into an “inner” rollup proof, and 32 inner rollup proofs are aggregated into one “outer” rollup proof, which will be eventually verified by nodes and posted onto Layer 1.



Aztec Protocol has designed a set of development modules to help developers build decentralized applications that ensure confidentiality.

Currently, Aztec offers seven toolkits:

Join Split (Transfer): The Join Split proof allows a set of input notes to be joined or split into a set of output notes and ensures that the sum of the input notes is equal to the sum of the output notes.
Bilateral Swap (Trade): The Bilateral Swap proof allows users to swap notes. This is useful for trading two assets (e.g., trading fiat for bond or collateral). It proves that the makers bid note is equal to the takers ask note and the makers ask note is equal to the takers bid note.
Dividend: This proof allows the prover to prove that the input note is equal to an output note multiplied by a ratio. It is useful for examining whether the interest from an asset is correct.
Mint: The Mint proof allows the supply of Aztec notes to be increased by a trusted party. For instance, a stablecoin mints an Aztec note equal to the value of a bank transfer it receives.
Burn: The Burn proof allows trusted parties to burn Aztec notes. For instance, a stablecoin burns an Aztec note with an equal value of the bank transfer it sends to the note owner.
Private Range: This is used to prove that an Aztec note is greater than another Aztec note, or vice versa.
Public Range: This is used to prove that an Aztec note is greater than a public integer, or vice versa.
Conclusion
The Web 3.0 narrative emphasizes the user’s identity and data ownership. Users must have privacy on the blockchain or network, which turns privacy-preserving computation into an essential requirement of Web 3.0. Blockchains without privacy protection are exposed to many risks. For instance, on such chains, assets are less secure, and operations could be tracked and also face the risk of censorship, making it hard to build and develop commercial applications on blockchains.

If public chains could ensure privacy and achieve programmability, high performance, compatibility, and compliance, then they could be extensively adopted for commercial purposes. As a type of Layer 1 infrastructure, privacy-preserving public chains are competitive players in the category of new public chains and have broad, promising prospects.

Recently, Supremacy, a blockchain security team, tweeted that the contract of DeFi investment management tool Earning. Farm suffered a flash loan attack, through which MEV bots earned 480 ETH and the hacker made a profit of 268 ETH.

Though veteran DeFi users are very familiar with flash loans, the term could be confusing for many crypto beginners. In this article, we will focus on flash loans and help new crypto users understand these loans that are unique to the crypto space.


Types of loans

We are all familiar with loans in everyday life. There are two types of typical loans: secured loans and unsecured loans. For example, if someone needs funds to start a business, he can apply for a loan to a bank with his property as collateral. The borrower will still own the property once the loan is repaid. However, if he fails to repay the loan when it becomes due, the bank will be entitled to take away his property.

Unsecured loans, also called credit loans, including the credit cards that we use when shopping in a mall. As such loans are unsecured, the bank will check your credit records and cash flow when you apply for a credit card to make sure that you’ll be able to repay the loans.

In DeFi, lending is also one of the most frequent use cases. In our previous article ViaWallet｜What is Decentralized Lending, we elaborated on the most common over-collateralized loans in decentralized lending. In addition to secured loans, decentralized lending also offers unsecured loans called flash loans, which are our focus today.

Flash loans explained

Simply put, flash loans describe a process of borrowing and repaying loans in the same block. In the case of Ethereum, we should first make it clear that a block can accommodate multiple transactions, and one transaction can involve many steps. As shown in the picture below, this particular transaction involves 24 transfer records.



This means that we can include the following steps in one transaction: Borrow a loan, spend the loaned funds on something, and repay the loan. Unlike regular interactions, these steps must be put into a transaction through programming in the specified order. Once the last step (repaying the loan) is completed, the steps will be packaged into the transaction and uploaded onto the blockchain. Meanwhile, if the steps included even one error (e.g. the loan was not repaid), then the whole transaction would be rolled back, and the transaction would fail.

Therefore, in this case, the flash loan provider does not worry about the borrower’s ability to repay, and it only needs to adjust the contract so that the borrower must repay the loan within the same transaction. In this way, the loan will be revoked automatically if it is not repaid. Since all records will be rolled back, there is no risk of default.

Use cases of flash loans

Now that you know how flash loans work, you might ask a new question: what’s the use of flash loans if they can be instantly borrowed and repaid? In fact, flash loans have a lot of use cases. Most typically, flash loans are used for arbitrage.

To veteran traders, arbitrage is nothing new. It refers to the process of buying low on one exchange and selling high on another when there is a price gap between the two exchanges. The more funds you’ve got, the more arbitrage opportunities there will be, and the larger the arbitrage profit. In this context, flash loans provide users access to massive funds.

Suppose you could now swap 1 USDC for 1.01 USDT on UniSwap and exchange 1 USDT for 1 USDC on Curve. You could then borrow 100,000 USDC through a flash loan and sell the borrowed crypto on UniSwap to get 101,000 USDT. Then, you could trade the USDT for 101,000 USDC. Finally, you repay the 100,000 USDC flash loan, which means that you would get 1,000 USDC without paying a dime.

Of course, the above case is merely an example, and arbitrage through flash loans involves much more complicated operations. To start with, flash loan providers charge a certain fee. Moreover, large transactions often come with significant slippages, in which case you wouldn’t be able to swap cryptos at the current price. As such, real-world arbitrage through flash loans is more subtle and involves more accurate timing. In addition to arbitrage, flash loans are also used for liquidation. For instance, some users conduct self-liquidation through flash loans to reduce the cost of liquidation.

Flash loans can also be exploited by hackers to launch flash loan attacks, which refer to the process of earning huge profits by manipulating the crypto prices using massive funds. Such behaviors often cause losses to other users, and are thus regarded as malicious attacks.

For example, suppose a hacker borrowed 10,000 ETH through a flash loan to attack a DeFi protocol that allows him to swap 1 ETH for 1,500 USDT. He would first convert all the ETH borrowed into USDC. At this point, the ETH price would plummet due to the large order, and 1 ETH can now only be swapped for 750 USDC, allowing the hacker to make a profit of 11,250,000 USDT (as the AMM algorithm and the K value are both uncertain, the figure is for reference only and does not reflect actual price changes). Subsequently, the hacker borrows cryptos on the same platforms. At the current swap rate (1 ETH: 750 USDC), according to the collateral ratio of 75%, he could borrow 11,250 ETH with his USDC holding, which means that the hacker would get 1,250 ETH after he pays off the flash loan. While the hacker made a huge windfall, he also brought an enormous impact on the market prices.

Controversial as flash loans are, most people believe that hackers could still pull off similar attacks using massive funds even without flash loans because such attacks exploit the flaws of the oracle mechanism of the relevant protocols. Flash loans, a type of loans unique to DeFi, are undoubtedly innovative. As a typical case of code execution, these loans might inspire new ways to design financial products in the future.

Since CryptoPunks introduced pixel art into NFTs, all kinds of picture formats and artistic styles, covering anime, mechanics, and minimalism, have entered the NFT market. This, together with the appearance of celebrity NFT holders last year, has sent the prices of NFTs soaring. Later on, big corporations in different sectors soon followed suit and also started to pursue NFT innovations, with a focus on artworks and collectibles. Relying on their unique ownership features in the digital world, NFTs have huge potential in all fields. That said, compared to categories such as GameFi and artworks, the sports industry only offers a few NFTs.

Against such a background, CoinEx Rugby Players NFTs provide a chance for large sports leagues to foray into the NFT market. This new NFT series represents the cross-sector collaboration between NFTs and the mainstream sports community. It is a good practice made by the blockchain space and the sports industry.



As ownership proofs of crypto assets, NFTs will power the growth of the sports memorabilia market, and NFT sports collectibles are expected to reach $92 billion by 2032, according to the research data provided by Market Decipher. Over the past few years, the real-world sports memorabilia market has always been fueled by huge demands, which enabled a significant increase in prices. However, due to geographical limits, physical memorabilia are not readily available to sports fans around the world. CoinEx Rugby Players NFTs, on the other hand, transcend all barriers and allow rugby fans from all over the world to buy NFTs on OneSwap NFT anytime, anywhere.

OneSwap NFT is an NFT marketplace recently launched by CoinEx Smart Chain (CSC). As a bridge between NFT sellers and buyers, the marketplace enables users to mint, buy, and sell crypto artworks and digital collectibles. Covering NFT categories that include charity, arts, entertainment, game, sports, and collectibles, OneSwap NFT makes NFT trading easier through user-friendly webpages and easy operations.

OneSwap NFT, built on CSC, offers negligible gas fees thanks to CSC’s ensured efficiency and low rates. In addition, the marketplace allows users to mint NFTs for free, which minimizes the minting cost.

Unlike most NFT marketplaces that require an exorbitant fee of 2.5%-15% for each NFT transaction, OneSwap NFT only charges a fixed fee of 2%. This holder-friendly rate is lower than the rate charged by most NFT marketplaces.

Log in to OneSwap ( https://www.oneswap.net/cet), and connect your wallet with your OneSwap account;


2. Click “Collections” on the NFT page, and select “CoinEx Rugby Players”;


3. Pick your favorite NFT in the collection, and click on it to place a bid.



Sport event’s push for the crypto economy will be seen at the World Cup, where NFTS are among the tracks being watched. Linking the crypto space with mainstream communities, NFTs have become an identity or credential in the real world, so NFTs are increasingly integrated with sports. CoinEx Rugby Players NFTs are such a case that demonstrates the successful combination between the crypto economy and a top sports event. We look forward to seeing more cross-sector NFTs on OneSwap NFT.

Live AMA with industry bigwigs: Will decentralized derivatives trigger the next DeFi Summer?

During this AMA, professional investors and project founders expressed their opinions on the future of DeFi and the problems facing it. (This does not constitute any investment advice.)

Speaking of the future of DeFi, almost all the guests agreed that “DeFi will make a comeback in the next bull market” yet there would be more room for its development. They believed that DeFi would witness some innovations at that time, with compelling breakthroughs in use cases, and would rise as one of the major crypto applications.

In the discussion about the unnecessarily high threshold for individual investors to the DeFi world, Aperture CEO Lian Zhu suggested that DeFi project developers should assume the responsibilities of educating users, especially those who prefer speculation to investment. Eduard, founder of ZKX, proposed technically simplifying user experience to attract more users. May, partner of Volare, also advised, from the perspective of products, that trading platforms be used to help users invest. All these suggestions provided great insights for DeFi project developers.

For the question of how DeFi derivatives will attract more traditional finance customers to the crypto world in the future, Arthur, founder of DeFiance Capital, believed that the majority of traditional finance users have already entered the crypto space and DeFi derivatives would send the number growing. Michael, board member of DefiYield, analyzed from the perspective of institutions and pointed out that many derivatives platforms target institutional players and many legacy financial institutions are ready to engage in this field or show interest in it, which will bring more resources for the development of DeFi derivatives and attract more traditional finance customers.

This AMA went deep into topics such as the future development of DeFi and user demand. Guests all made penetrating comments on the current situation and potential of DeFi as senior investors and insiders. The real-time communication with the audience also attracted much attention.

Standing at a new starting point and looking into the bright future

ViaBTC Capital believes that, in a bear market, priorities should lie in a balanced portfolio and the good integration between the subjective preference and the market preference. Project teams should emphasize self-development, be brave to admit mistakes and maintain optimism. Looking ahead, ViaBTC Capital expressed its confidence in the future of blockchain. It will stick to value investing, advance with the times and bring more benefits to project developers, thereby accelerating the development of blockchain technologies and applications.
