i believe the mentioned exchanges - binance, kucoin and ftx are good exchanges all the same. but of course, for storing your coins, better not to store with exchanges. kucoin are still allowing nonkyc users on their platform and they have pretty good liquidity as well. been using that exchange also and so far no prob. the good thing with binance though is if you are using their p2p services, which is very useful to convert your crypto to your own fiat ( if it is supported), and also their safu in place.
