**DeFi platform opens up more opportunities for users to profit through Farming or Staking with high interest rates. However, profits always come with risks, if you do not have enough knowledge and understanding of the project, you will be at risk of having your crypto wallet hacked. In this article, BHO Network will show you how to keep your crypto wallet safe when participating in DeFi.**

# Causes of cryptocurrency wallet hacks 

![Screenshot 2022-09-22 182036.png](https://cdn.bho.network/cms/Screenshot_2022_09_22_182036_a7640b0635.png)

First, the cause of the crypto wallet hack can come from Farming. This is the activity to provide liquidity to DeFi protocols or platforms. Participants can earn more profits, and for developers, there is more liquidity in the pool to stay active.
- To perform Farming, you must first connect a crypto wallet to the platform through the “Approve” step (to enable the transaction). This is a mandatory step when participating in farming or coin/token swap.
- This “Approve” action will allow smart contract developers of the farming platform to interact with your coins used to feed into the liquidity pool. And this is also a possible cause of crypto wallet hacking. 
- Hackers will take advantage of the vulnerability in the Approve operation to swap your coins/tokens to other coins/tokens then withdraw liquidity and disappear. 
- Furthermore, the Approve operation also has an unlimited review feature called Unlimited Approve that allows the protocol and smart contract to have full control of your funds (maximum usage limit). This has the advantage that it will save you transaction costs, just Approve the first time to execute the next orders and operations. However, this is also the risk of losing all assets when giving all authority to a smart contract developer.

One more reason leading to the risk of being hacked for a crypto wallet is that the wallet receives a lot of strange coins/tokens that you have never traded or interacted with, or the platforms that have that coin/token. This is a trick where hackers take advantage of a security vulnerability to add more codes to Approve to trade for all the tokens in your wallet. Therefore when you trade that coin/token on DEX or send it to another wallet, the remaining amount on your wallet will be at risk of being taken over by hackers, or will be completely evaporated after the transaction takes place.

# Keeping crypto wallets safe in DeFi

## Store assets in various crypto wallets
You should split your coins/tokens into many different wallets for storage. Besides, you can keep a separate wallet just to store long-term coins/token holdings and ensure that this wallet will not interact with any smart contracts or DeFi platforms.

When you need Farming, you can calculate the number of coins/tokens needed to join and transfer to another wallet for Farming, or transfer coins/tokens directly from the exchange to a new wallet. This will help you minimize your risk, where if you accidentally encounter a scam project, you will only lose the coins/token in the Farm wallet, not everything.

## Instructions for safe storage of Private Key and Seed Phrase
There is no perfect way to store Private Key and Seed Phrase, only a way that works better for everyone. However, you can refer to the following methods:
- Save on both (physical) sticky notes and online storage (Google Drive, ...). However, you should not save by regular mail, instead create a separate email, set up 2FA and don't log in anywhere to save space.
- You have to save it in various places, from disk drives to sticky notes, in a way that other people can't steal the key. You can change some characters or change the order of the Private Key and Seed Phrase that only you know (e.g. change the order of the first and last letters, ...)
- For files saved online, enable more protection modes per file (Excel allows enabling passwords for the entire Excel file or for individual Tabs in the file).
- Last but not least, some don't always save the key when creating the wallet. BHO Network recommends that you create a key right after creating a wallet, if you are too lazy to save many keys, save a Seed Phrase and create multiple sub-accounts.

## Review the project before Farming or Swap coins/tokens
Before Farming, you should learn more about the project to see if it is reliable through a few questions like:
- Has the project been audited?
- Who are the project team members? 
- Project development roadmap and technology?
- …

Therefore, if a project promotes a high interest rate (APR) but has not been verified, it should not be farmed because the possibility of losing your money is very high.

When Farming, you should consider when choosing the Unlimited Approve feature. Although it will cost you time, and the cost of each farming is a mandatory Approve, it will ensure your assets are safe.

In addition, you should be careful when you have strange tokens sent to your wallet. Almost any amount of scam token will be sent in thousands and millions to spark your greed. This has caused a lot of newcomers to DeFi who do not know, and they will find a way to quickly swap them. But after the swap is complete, the money in their wallet will disappear.

One thing to keep in mind is that after Farming, Swap or interact with dApps, you need to disconnect from these dApps.

# Instructions for DeFi safely with 3S Wallet

Guide to crypto wallet safety in DeFi

**To start participating in the DeFi platform and interacting with dApps, you need to connect those dApps to your crypto wallet. In this article, BHO Network will provide you with information and guidance on a crypto wallet that makes it easy for you to use when joining the DeFi platform.**

# DeFi crypto wallet overview
A crypto wallet is software that allows users to store, manage, and trade their coins/tokens. Besides, with the DeFi platform, the crypto wallet is the key to connecting and interacting with dApps.

## Main components of a crypto wallet
Crypto wallets for DeFi usually have 3 main components:
Public Key: Is the public key used to send and receive coins/tokens, similar to a bank account
Private Key: A private key just like a pin or password to access your bank account. However, the Private Key is different in that it cannot be changed.
Seed Phrase: A secret key phrase of 12-24 characters, which is randomly generated when creating a crypto wallet, and is used to restore the wallet in case you change your device or forget your Private Key.



![Screenshot 2022-09-17 184959.png](https://cdn.bho.network/cms/Screenshot_2022_09_17_184959_1a37ac7279.png)

## How crypto wallet works
The coins/tokens transaction of a crypto wallet is not the same as sending and receiving money in banking applications. When you made a coins/tokens deposit, you used your Private Key to sign the transaction and broadcast it to the blockchain network. The network will then include your transaction to reflect the updated balance in your address and the recipient's. 

The term 'wallet' can be misleading because crypto wallets don't actually store coins/tokens in the same way that physical wallets hold cash. Instead, the crypto wallet will read the public ledger to show the balance in the wallet address, and hold and use the Private Key allowing you to make transactions and interact on dApps.

Therefore, the main activity of a crypto wallet is that you confirm your coins/tokens’ sending/receiving address on the blockchain network through your Private Key. Speed and security often depend on the type of wallet you have.

# Why you need a crypto wallet
Your cryptocurrency is only as safe as the method you use to store it. While it is technically possible to store cryptocurrencies directly on an exchange, you should not do so unless in small amounts or if you plan to trade frequently. 

For larger amounts, it is recommended to withdraw most of it to a crypto wallet. This way, you retain ownership of your Private Key and have complete control over your own finances. 

However, when using a crypto wallet, you need to keep your Private Key and Seed Phrase safe, losing them means losing access to your wallet. Therefore you need to store securely and choose a reliable wallet provider.

# How to create a crypto wallet?

6 best crypto wallets for iOS (iPhone, iPad)

**The crypto market is growing and changing rapidly. New ecosystems are constantly being launched, and have made great strides to attract many users. The need to store coins/tokens does not stop on one blockchain anymore, but now becomes the want to experience transactions on dApps in many different blockchains such as BSC, Polygon, BHO Chain, Solana, etc. In this article, BHO Network will provide you with information about Multi-chain wallets and things to know about Multi-chain wallets.**

# What is a Multi-chain Wallet?
Multi-chain wallet is a cryptocurrency wallet that can integrate multiple wallet addresses from many different blockchains on the same application called wallet software.

Through it, Multi-chain Wallet helps you receive, transfer and store multiple coins and tokens on multiple blockchains in the same wallet, using only a single seed phrase. In particular, the wallet will be owned by you and no one or third party has the right to affect or access your assets, unless you give permission.

There are two very important information about Multi-chain wallet that you must take note of:
- Seed Phrase: There is only one key phrase to manage all wallets on different blockchains. 
- Wallet Address: According to the wallet address format of each independent blockchain, each network will have a different wallet address. However, with blockchains built on EVM virtual machines such as Ethereum, BSC, HECO Chain, Polygon and Fantom, the wallet address will be the same. 

# Benefits of using a Multi-chain wallet
As the number of public blockchains increases, users will often hold multiple digital assets (coins/tokens) on multiple public blockchains at the same time. If each digital asset of a public blockchain requires a Single-Chain wallet to store and trade, it will become cumbersome and difficult to use, as users will need to install multiple Single-chain wallets and manage multiple Seed Phrases. This is equivalent to having too many bank accounts and having to remember many different login accounts. 

Therefore, it is necessary to develop a Multi-chain wallet to store and trade multiple coins/tokens on different blockchains. Now, you just need to create a Multi-chain wallet and just remember a Seed Phrase, and you will find it much easier and more convenient to manage coin/token storage wallets of multiple blockchains at the same time.

# How to create a Multi-chain wallet?
To start using a Multi-chain wallet, you can learn and create a [3S Wallet](https://3swallet.com/) from BHO Network.

3S Wallet is a Multi-chain cryptocurrency wallet that supports many networks such as: Ethereum, Binance Smart Chain, Polygon, Fantom, Avalanche, Optimistic, Arbitrum, Cronos, Solana, and BHO Chain.

# Multi-chain Wallet FAQs
## What coins/tokens can be stored on a Multi-chain wallet?
Depending on the Multi-chain wallets from different providers, different amounts of tokens will be supported. 3S Wallet currently supports storage of many popular coins/tokens including: Ethereum, Binance Smart Chain, Polygon, Fantom, Avalanche, Optimistic, Arbitrum, Cronos, Solana, BHO Chain, etc.

## Is it safe to use a Multi-chain Wallet?
Multi-chain wallet is a decentralized wallet. In essence, the coin/token is not stored in a wallet but will exist on a blockchain, and the wallet is a middleware that allows you to interact with the coin/token balance available on that blockchain. Through it, the Multi-chain Wallet only stores the address and allows the holder to send and receive the coin/token elsewhere, or view the existing balance on the wallet.

Therefore, the Multi-chain wallet is completely under the control of the user, and it's safe when the Seed Phrase is securely stored. 

## Are there transaction fees when using a Multi-chain wallet?
When making transactions from Multi-chain wallets to dApps, or you swap directly in 3S Wallet, you will have to pay the platform transaction fee of the blockchain you use. 

Different blockchains will have different transaction fees. For example, when you trade on BNB Chain network, you have to pay fees in BNB, or if you trade on Polygon, you have to pay fees in Matic.

## Is it possible to create multiple multi-chain wallets?
You can create many different Multi-chain wallets on the 3S Wallet application. However, you need to remember and secure your login information and Seed Phrase.

5 safe and popular crypto wallets in 2022

**When trading in the crypto market, you need to store coin/token assets on a crypto wallet. So what is a crypto wallet? How important are crypto wallets? In this article, BHO Network will provide everything you need to know about crypto wallets.**

# What is a crypto wallet?
A crypto wallet is a software used to store information that allows sending, receiving and tracking balances of coins/tokens. 

![h1 (3).png](https://cdn.bho.network/cms/h1_3_4f03e1d1ac.png)

In simpler terms, a crypto wallet is like a bank account, but this wallet has higher security. Thanks to the information encryption mechanism, the owner of the wallet cannot be identified, and the money is stored in the wallet in the form of coins/tokens.

# Components of a crypto wallet
Crypto wallets have three main components: Public Key, Private Key, Seed Phrase

## Public Key - Wallet Address

![h2.jpg](https://cdn.bho.network/cms/h2_393e4d2eb2.jpg)

Public Key, also known as wallet address, is random information consisting of alphanumeric characters. A Public Key is used similarly to a bank account number. You will use the Public Key so that someone can send coins/tokens to your wallet.

In addition, the Public Key is also considered as the user's address on the blockchain network. However, different blockchain wallet addresses will have different structures depending on the network. If networks are built from EVM Compatible, they will usually start with 0x…, while non-EVM networks will be a random string of characters.


## Private Key 

![h3 (3).png](https://cdn.bho.network/cms/h3_3_ac8fea4286.png)

Private Key is also a random string of numbers and letters to connect a wallet. A Private Key, as its name suggests, will be used secretly to log into the wallet. To put it simply, a Private Key is like a bank password, but while the bank password can be changed, the Private Key cannot.

The structure of the Private Key is not based on any standards, it is just a random string of characters, whether in the same network or not.

When using wallets across platforms, you need to store your Private Key as this will be the only key to access your crypto wallet. In addition, you must not reveal this code to anyone. If you lose your Private Key, you will no longer be able to access the wallet.

## Seed phrase 

![h4 (2).png](https://cdn.bho.network/cms/h4_2_2ca64e31af.png)

Seed phrase, Passphrase, Mnemonic or Recovery phrase are all popular terms when using a crypto wallet. Although those terms have different names, they all have the same effect of creating a secure key phrase for the wallet. This keyword phrase will consist of random English words of 12 or 24 words. However, wallets will have different decryption mechanisms to give different wallet addresses. Therefore, it is necessary to carefully record the Seed phrase used for which wallet in order to restore the correct wallet.

A Seed phrase example: convince between family solve into slam labor boy demand song october sun

With the same Seed phrase as above:
- When using Trust wallet, this will be the wallet address: TPza8thrTfG64XzyZoMbGEjpuyaBUJBsN9
- When using 3S Wallet, this will be the wallet address: PLza5cklTfGa4XzyZoMbGEjpuyertnkHFHS9N9

# Mechanics Description
Blockchain is essentially a public ledger that stores data in the form of "blocks". These are records of all transactions, balances held at any given address, and who holds the keys to those balances. 

The coin/token is not actually stored "in" the wallet. These coins exist on a blockchain, and wallet software allows you to interact with balances held on that blockchain. Wallets themselves only store addresses and allow their owners to transfer funds elsewhere while also allowing others to view balances held at any given address.

![h5.jpg](https://cdn.bho.network/cms/h5_0de6a38d4a.jpg)

While each crypto wallet has a few distinct characteristics, most have the following features related to sending or receiving funds:
- To receive funds, you need to get an address (also known as a public key) from your wallet. Find the "generate address" feature in your wallet, click it, then copy the alphanumeric address or QR code and share it with the person who wants to send you crypto.
- To send money, you need the address of the receiving wallet. Find the "Send" feature in your wallet and enter the address of the wallet you intend to send money to. Select the amount of crypto you want to send and click "Confirm". You should consider sending a small test transaction before sending a large amount of crypto.
- Note that sending coins/tokens will require a fee that will be paid to the network in exchange for processing the transaction.

Sending money via QR codes or long strings of numbers and letters may seem strange at first, but after doing it a few times, the process becomes quite simple, and can avoid mistakes by missing characters when copying, or having some malicious code that can change characters during your copy.

# Crypto wallet classification

## Centralized wallet
A Centralized Wallet is often used when you trade coin/token on centralized exchanges (CEX) such as Binance, FTX… (Similar to using bank cards at banks)

When you create an account on any exchange, the exchange will automatically create a wallet that allows you to trade all coins/tokens listed on the exchange. You just need to use the correct coin/token you want to deposit, withdraw or trade. Therefore, you don't need to remember the private key, just remember the login information to the exchange.

Pros: No need to create a crypto wallet, just create a trading account

Cons: 
- Security is not as high as decentralized wallets. 
- Your crypto wallet will be 100% controlled by the exchange.
- Risk from a 3rd party (the exchange) if problems occur.

## Decentralized wallet
Decentralized wallet has two types: hot wallet and cold wallet.

### Hot wallet
A type of software wallet, you can make a transaction anytime through an internet connection.
- Pros: More variety and options, and easy to connect via wallet extensions on browsers or mobile apps
- Cons: Easier to be attacked by hackers than cold wallets because the data about the Private Key is stored right in the Extension or App and is always connected to the network.

### Cold wallet
A graspable physical wallet shaped like a USB. Cold wallets work similarly to a bank account. Automatically receive money when someone sends you money when not connecting the wallet. To check, connect your wallet to a computer with internet
- Pros: Higher security.
- Cons: Lack of flexibility in use and high cost.

## Multi-chain wallet
A multi-chain wallet is used to support many coins/tokens that can be used on different blockchains at the same time. Multi-chain wallets make it easier to manage coins/tokens because only 1 passphrase needs to be stored for multiple wallets.

For example, 3S Wallet already supports many networks such as: Ethereum, Binance Smart Chain, Polygon, Fantom, Avalanche, Optimistic, Arbitrum, Cronos, Solana and BHO Chain. Not stopping there, 3S Wallet will continue to support more networks in the future to bring the most convenience to users.

# Why you need to use a crypto wallet
Unlike regular wallets, which can hold actual cash, as described in the operation section, crypto wallets do not store your coins/tokens. Thus, your assets are on the blockchain, but can only be accessed by crypto wallets via Private Key. 

Your keys prove ownership of your coins/tokens and allow you to make transactions. If you lose your private keys, you will lose access to your funds. That's why it's important to keep your crypto wallet safe or use a trusted wallet provider.

Currently, BHO Network is also providing 3S Wallet - a crypto wallet with outstanding features such as: multi-chain transaction support, one-touch interface, optimized user experience.... You can learn more and use it HERE

**Above is all the information you need to know when using a crypto wallet. BHO Network hopes to help you understand the importance of a cryptocurrency wallet so that you can use it more conveniently in the process of trading and investing.**

What is a crypto wallet? All you need to know about crypto wallets

**In this article, BHO Network will introduce in detail about decentralized exchange (DEX), including: how it works, the pros, cons, and popular decentralized exchanges today.**

# What is DEX?
DEX stands for Decentralized Exchange. This type of exchange is built and operates on the blockchain technology platform, allowing peer-to-peer coin/token trading right on the blockchain network without going through any intermediary organizations or agencies. Therefore, users can control their money and trading activities proactively. 

# How does DEX work?
**Trading activities:** Users who want to trade coins/tokens on a DEX need to have an e-wallet and hold a private key to connect to the exchange. 
- The most popular decentralized exchanges (DEXs) today are usually AMM (Automated Market Makers) DEXs. This is a tool that provides automated liquidity to exchanges. Here the transaction will take place through the pooling of liquidity into smart contracts. Projects need to provide their coin/token pairs to create a liquidity pool. In addition, DEX exchanges also incentivize users to add liquidity by depositing coin/token pairs that match the exchange's liquidity pool. 
- When users make trades, an AMM DEX will automatically match orders based on the available liquidity pool. However, if the liquidity pool is not fully funded, it will lead to very high price slippage. Therefore, when trading on a DEX, you need to pay attention to liquidity and slippage rate before deciding to make a trade.

**Transaction fee:** The transaction fee of DEXs usually depends on the coin/token price of each ecosystem at the time of transaction. The Ethereum network currently has the most expensive transaction fees compared to other blockchains. The average transaction fee on the ETH network is 3$-5$, but there are times when the transaction fee rises up to 30$-40$ (due to the high price of ETH coupled with a sudden surge in the number of transactions, which cause transaction fees to increase). Networks other than Ethereum like BNB, Polygon or Solana… have much cheaper fees, most of them are less than 0.1$.

**Trading regulations:** Trading on DEX does not require users to perform identity verification (KYC - Know Your Customer) or anti-money laundering (AML).

**Asset control:** DEXs do not store users' assets, so it is relatively safe to trade. You have full control and management of your coins/tokens. However, in case someone knows your wallet's private key, your assets will not be safe anymore.

# Pros and Cons of decentralized exchange (DEX)
## Pros
- **Privacy:** When trading at a DEX, you will not need to provide information for identity verification (KYC). All transactions are anonymous, and identified based on the e-wallet address.
- **Transparency:** Transactions are instantly recorded on the blockchain, which you can easily look up. Besides, you can also check on-chain for buying and selling information of wallets from “sharks” and project holding wallets for reference when making investment decisions.
- **Investment opportunities:** Due to not being too tightly controlled, DEXs also own more coins/tokens that have not been listed on centralized exchanges. This also helps increase investment opportunities when buying low-priced tokens at DEX exchanges, then when this token is listed on centralized exchanges (CEX), it may be sold at a higher price.
- **Control:** DEX is only an intermediary trading platform, so it does not hold users' coin/token assets. You will have control and management of your assets without depending on any middlemen.
## Cons
- **Liquidity:** Currently, the trading volume on DEXs is still much smaller than that of CEXs. The main reason is that the centralized exchanges have higher liquidity. Liquidity is a measure of how easy it is to buy and sell an asset at a fair price. Therefore in illiquid markets, your trades may not be executed quickly. Moreover, DEXs mostly depend on projects that add liquidity groups or users to provide liquidity, so most will not have an abundant liquidity source like CEXs.
- **Transaction fees:** High gas fees when the network is overloaded also makes users nervous when trading on DEXs. In addition to gas fees, users also need to pay attention to the issue of price slippage. In some cases of poor liquidity and fast price fluctuations, trading users will have to increase the slip rate to 10, or even 20%, to hope their trades will be executed.
- **User Interface:** DEX requires users to have more specialized knowledge when trading than on the CEX.
- **Potential for hackers:** Hackers take advantage of sending you some fake tokens. If you add those fake tokens to your wallet and accept transactions on certain DEXs, there is a possibility that hackers can break into your wallet and take all your assets. Therefore, it is very necessary to check the contract carefully before adding it to the e-wallet before executing any swap orders.

# Some of the most popular exchanges (DEX) today 
In today's crypto market, most ecosystems (private blockchains) have AMM DEXs. This is where the liquidity is generated and the first flow of money on the ecosystem is generated. BHO Network will introduce you to some of the popular exchanges today.

## Uniswap

![h1 (2).png](https://cdn.bho.network/cms/h1_2_31b2e3b6a3.png)

Uniswap is an AMM DEX built on the Ethereum blockchain network in 2018. With the Uniswap exchange, users can make any transactions with ERC-20 tokens. Currently, Uniswap is on the V3 version to better support users. Uniswap is one of the most popular DEXs, and has the largest trading volume among the DEXs today. 

At the time of writing, Uniswap's 24-hour trading volume is over $1 billion. There are 445 coins/tokens and 812 trading pairs available on the exchange.

## PancakeSwap 

![h2 (2).png](https://cdn.bho.network/cms/h2_2_404803aab9.png)

PancakeSwap is the first AMM DEX of the BNB Chain (formerly Binance Smart Chain) blockchain network. PancakeSwap was built in September 2020. 

Originally PancakeSwap was a fork of Uniswap. However, with the strong development of the BNB Chain ecosystem, PancakeSwap has also become more popular and is among the top 3 DEXs with the best liquidity today. Besides, thanks to the operation on the BNB chain (BSC), PancakeSwap has cheaper transaction fees and faster transaction processing speed than Uniswap.

At the time of writing, the 24-hour trading volume on PancakeSwap is over $100 million. There are 3582 coins/tokens and 4103 trading pairs available on the exchange.

## 1inch

![h3 (2).png](https://cdn.bho.network/cms/h3_2_1acf68dc01.png)

1inch is a DEX Aggregator Protocol built with a smart routing solution - Pathfinder. Therefore, 1inch allows users to trade tokens with the best price in the market with the lowest slippage. Currently, 1inch works on many blockchains (multi-chain) such as Ethereum, Polygon, BNB Chain (BSC). At 1inch, users can trade with any ERC-20 token. Recently 1inch also added CHI token to help reduce the maximum transaction fee for users.

At the time of writing, 1inch has a 24-hour trading volume of over $300k. There are 23 coins/tokens and 23 trading pairs available on the exchange.

# Summary
Currently, decentralized exchanges (DEXs) are working to improve user experience and build more use cases. CZ (founder of Binance) also thinks that in the future, DEXs will dominate the market of centralized exchanges (CEXs). In the long run, DEXs seem to be more in line with the potential of Web3, with the ideal of users not needing to trust third parties, and everything on the Internet will be completely decentralized. However, at the present time, if you are a newbie, you need to learn some more specialized knowledge to be able to use DEXs more easily.

**Those are some basic information about decentralized exchange (DEX) that BHO Network wants to provide. Hopefully, through this article, it will help you better understand DEX, so that you will be able to choose reputable DEXs to trade and protect your assets.**



In this article, BHO Network will introduce in detail about decentralized exchange (DEX), including: how it works, the pros, cons, and popular decentralized exchanges today.

What is a DEX? Learn more about Decentralized Exchange (DEX)

**To start buying and selling cryptocurrencies, investors will make transactions through cryptocurrency exchanges. In the crypto market, there are two types of exchanges, centralized exchanges (CEX) and decentralized exchanges (DEX). In this article, BHO Network will introduce in detail about centralized exchange (CEX) including: how it works, the pros & cons, and popular centralized exchanges today.**


# What is CEX?
CEX stands for Centralized Cryptocurrency Exchanges - or Centralized Exchanges. This exchange will be managed by large-scale cryptocurrency trading coordination organizations. The business model is similar to traditional asset exchanges such as stock exchanges.

In a nutshell, a centralized exchange (CEX) is a trusted third-party intermediary that provides trading, depositing and withdrawing services for cryptocurrencies and oversees the operations between buyers and sellers.

# How does a centralized exchange (CEX) work?
**Trading activities:** Centralized exchanges (CEX) will allow investors to buy and sell cryptocurrencies with fiat currency. For example, a centralized exchange in Vietnam will allow the use of VND to buy cryptocurrencies (USDT, USDC...), then buyers can choose the cryptocurrency trading pairs (BTC/USDT, ETH/USDT, etc.) that they desire. In addition, most exchanges also provide additional services including asset custody, trading limit setting, leveraged trading, borrowing - lending, etc.

**Transaction fee:** Like stock exchanges, centralized exchanges (CEX) will charge a transaction fee from users through each cryptocurrency purchase or sale. However, the transaction fee is also quite low, ranging from 0.1% to 1.5%.

**Trading Regulations:** Centralized exchanges (CEXs) are regulated by institutions, and therefore must also comply with the operating regulations of the countries where they are licensed to operate. So, the exchange must comply with the legal regulations on identity verification (KYC - Know Your Customer) and anti-money laundering (AML - Anti Money Laundering), and ensure the rights as well as safety of investors.

**Asset control:** Any crypto assets when deposited or purchased on a centralized exchange (CEX) will be managed and controlled by that exchange. In addition, there are cases where the exchange locks abnormal deposits and withdrawals, which will prevent the transaction from happening as desired by investors. Therefore, choosing a reputable and secure electronic trading platform is essential.

**Exchange Coin:** Currently, most exchanges issue their own exchange coins to serve their ecosystem. Therefore, the needs and uses of exchange coins are also different. However, in general, exchange coins will often have the following use cases and characteristics:

- Reduce transaction fees, easy to convert: When investors trade on the exchange, the transaction fee will be reduced if using exchange coins such as Binance coin (BNB), Gate token (GT), Huobi token (HT), etc. In addition, after the transaction, there will be a very small amount of cryptocurrencies that cannot be exchanged or sold for stablecoins, but can be converted to exchange coins for use, or collected for later liquidity.
 
- Account upgrade: When the trading account is upgraded to a VIP account, depending on the trading volume, investors will be rewarded with exchange coins, depending on the exchange's marketing campaigns. Some exchanges often apply this form such as Binance, Okex, Gate, etc.

- Launchpad participation: Holding a large number of exchange coins also helps investors to participate in early buying tokens of new projects listed on that exchange. Take the Binance exchange for example, the tokens opened on its Launchpad have very high returns (ROI).

- Share profits from the exchange’s revenue: Just like dividends in the stock market, investors who buy and hold exchange coins will be able to earn a portion of the profits from the exchange. Some exchanges have applied this form such as BitMax, Kucoin, etc.

- Furthermore, some exchange coins are built into a private blockchain that serves the entire ecosystem. That exchange coin will be used as transaction fees for dApps in that ecosystem, such as the BNB of the BNB chain ecosystem (formerly Binance Smart Chain).

# Pros & Cons of Centralized Exchange (CEX)
## Pros
- **User experience:** Centralized exchanges (CEX) often have a user-friendly interface, suitable for newbies to trade. In addition, the exchanges always have a 24/7 support team to help investors avoid asset loss during the process of buying and selling, depositing and withdrawing cryptocurrencies...
- **Processing speed:** Transactions on CEXs are faster than DEXs.
- **High liquidity:** It is easy to find buyers and sellers of cryptocurrencies on a centralized exchange. There is no liquidity limit like some projects at DEX products.
- **2FA and email-authentication:** a typical Centralized Exchange (CEX) also integrates private keys through advanced security protocols 2FA and email-authentication to better protect investors.

## Cons
- **Control:** All crypto assets on an exchange are 100% controlled by that exchange. The exchanges operate on the trust of investors.
- **Anti-money laundering taxes and fees:** Centralized exchanges must report to tax authorities in countries to avoid money laundering through the crypto market.
- **Potential risks of hacker attacks:** Investors still have the possibility of losing their assets when the exchange is attacked by hackers. In fact, there have been a number of centralized exchanges that have been hacked, such as Kucoin exchange with more than 200 million USD in 2020, AscendEx exchange with more than 77 million USD in December 2021, etc.
