Crypto is dominated by centralized exchanges, recommending anyone of them for you is like putting you inside a tiger cage and locking the key because they cannot be trusted, one day you will lose access to your fund, and no one would pray for such kind of thing, look at Binance.US for example, the security exchange commission also known as SEC is considering confiscating users fund because they believe they are into some shady and insider deals, they believe Binance.US have violated their laws and as such, they are demanding the court to give them the order to seize the fund under Binance.US custody until all investigations are done, they are trying to seize users fund that belongs to customers which is a very bad move. It is always advisable you move your coins into self-custody for the safety of your funds and, lastly, never do KYC on any exchange, that's giving out your privacy to another company that cannot be trusted.
