lately I've been trying to do without cex exchanges, because the recent mandatory verification on binance is still not good news, I advise you to use dex exchanges when you always have your coins and tokens in your wallet, and don't worry about blocking your account, as it happens in cex.
As long as there are such high commissions in the Ethereum network, it is impossible to do without centralized exchanges. And those decentralized exchanges that use alternative blockchains with low fees will greatly limit you in choosing a coin for exchange.
If OP is a fan of margin trading, then the exchange bybit.com will be the best choice for him.
