Centralize exchanges continue to block accounts of users. That is why many users do not trust centralize exchanges.
Adoption of cryptocurrency grows and many investors and traders prefer to use decentralize exchanges why can not block accounts of users.
Of course, it is better to use decentralized exchanges than centralized exchanges, because many investors use decentralized exchanges, I also don't recommend for centralized exchanges, because I heard a lot of hackers doing hacks on such centralized exchanges.
