The main disadvantages of a decentralized exchange are:🌐 

1. Complexity of use. 

2. Limited features. Decentralized exchanges often offer a limited set of features compared to centralized platforms.

3. Low liquidity.

4. Lack of regulation.

5. Risk of losing funds. Like any other cryptocurrency platform, DEXs are subject to the risk of hacking and fraud.

6. Scalability issues. Some DEXs may experience scalability issues due to the large number of transactions.

7. Technical difficulties. Using a DEX requires an understanding of how blockchain and smart contracts work.

8. Unpredictable changes in the protocol. In the case of DEXs based on smart contracts, any changes in the protocol code can affect the operation of the platform and lead to unforeseen consequences for users.

10. Price volatility.
