I am on Binance but I want to buy some coins that they don't have. Later, I might consider to do also trading on that particular exchange.
So, is there any top5 of exchanges based on available coins, trading volume, fees, other criteria? As I'm on Binance, KYC is not a concern.
KYC is a big concern, especially if you spread it among multiple centralized exchanges because you are increasing chances for your data to be exposed with some future hack or leak.
Best alternative for Binance is decentralized exchanges like Bisq for example, you can use it without any verification and you will own the keys of coins you use for trading there.
