⑸ What is dex in the currency circle?

Hello, the full name of DEX is Decentralized exchange, which is a decentralized exchange. It is a block-basedA chain-based exchange that does not store user funds and personal data on servers, but only serves as an infrastructure to match buyers and sellers who want to buy and sell digital assets. This transaction happens directly between participants (peer-to-peer) with the help of a matching engine.

So, what are the advantages and disadvantages of new trading methods such as currency circle DEX?

Advantages of DEX:
Unlike centralized exchanges that store and control customers’ assets, decentralized exchanges do not control customers’ assets. Instead, assets are stored in a distributed fashion, usually by users or the exchange software itself. This way, there is no single entity that is the owner of all cryptocurrencies on the exchange, and the risk of loss is much lower.

Two main features of DEX:
1. Anonymity. Using a centralized exchange only requires a public key. At the same time, the creators of some centralized exchanges claim that they only release open source software and are not responsible for the community’s use of the software, thereby avoiding KYC and AML issues.

2. Security. In the past 10 years, more than 30 centralized exchanges have been hacked. Until now, hackers' attempts to steal have never stopped. Every day, hackers are trying to find loopholes to invade centralized systems through various methods. Since decentralized exchanges exist within computer networks, it becomes more difficult to attack decentralized exchanges. This makes decentralized trading much more secure as there is no single point of entry or failure.

DEX exchange disadvantages:
1. Low liquidity and adoption rate
Decentralized exchanges are still not as popular as centralized exchanges. As a result, they have fewer clients, trading volumes and liquidity, and trades take much longer to settle. Currently, DEXs trading volume accounts for approximately 1.5% of cryptocurrency market trading volume.

2. No professional trading
Due to the lack of advanced trading options, it is less convenient for professional traders to use decentralized exchanges. Therefore, algorithmic trading and high-frequency trading are very difficult in a distributed environment.

3. Lack of ease of use
Using decentralized exchanges usually requires connecting to a DApp or even installing an offline decentralized exchange client. In such cases, you may need to configure a separate node and stay online for an extended period of time to complete transactions.

4. Minimal Customer Support
Most decentralized exchanges fail to provide customers with any suitable support services, or accessible channels to influence trading or user accounts.
