Buying crypto on a decentralized exchange (DEX) can be safe, but it requires caution. DEXs offer enhanced privacy and control over your assets, as they operate without intermediaries. However, they also come with risks such as smart contract vulnerabilities, lack of customer support, and potential for scams. Ensure you use well-reviewed DEXs, double-check contract addresses, and use secure wallets. Stay informed about the latest security practices to mitigate risks and safeguard your investments.
