If you are a versatile trader who likes to trade a lot of coins and find hidden gems to invest in, then Kucoin is a much better choice for you, Kucoin gives you tons of coins and some decent volumes in most of them, even though most of it is derived from AMM but anyways, FTX on the other hand, has limited coins but has very good volumes in all of them, primarily because they are just the top coins, moreover FTX brings a lot of derivatives for you, which is not the case in Kucoin. Even though all crypto exchanges have some allegations against them but if you would tell me to compare them, FTX has somewhat a better name & reputation for itself than Kucoin, but Kucoin is older than FTX so that sort of balances the game.
