Decentralized exchanges, or DEX, are a less-common way to purchase cryptocurrency.
These exchanges offer some additional security. (Because they’re decentralized, there is no single target for a cyberattack.)
Their fees can also be lower.
However, DEX are less user-friendly and require more advanced technical knowledge to navigate. For example, decentralized exchanges don’t always let you deposit U.S. dollars and exchange them for crypto.
