Kucoin and FTX have good features you can use both exchanges according to your requirements, Kucoin has supported almost all pairs and deposit withdrawals for many chains and trade without KCY and fast withdrawal as compared to FTX have required KYC for withdrawals and low fees for ETH and some networks no fees but not supported many networks.
Kucoin is not an exchange that requires KYC? I honestly have never used Kucoin but I am actively using FTX, and currently FTX has accepted many chain when withdrawing or depositing such as solana, tron, and erc.
