if you say non kyc exchange are this the one who allows you to use their spot and future platforms? there are some but their are limits on withdrawals, like MEXC, bybit, coinex
for mexc 10 btc withdrawal higher needs, needs verified user, and for coinnex  ten thousand dollars per day, and bybit twenty thousand dollar per day, for non verified users, I use mexc before and without kyc its okay, regarding the user friendly i find bybit and mexc to be easy to use in spot trading's.
