I still use Kucoin as a centralized exchange without KYC and very friendly. I admit that Kucoin does facilitate features for non-KYC so it's easier and faster to withdraw.
One more thing I know of an exchange without KYC is a MEXC exchange before I also used this and until now if lower withdrawals KYC is not required.
It might be one of the under-asset exchanges for us to use, but it's been pretty comfortable as long as there haven't been any issues.
MEXC is my favorite exchange too because a lot of new coins are listed right away and this Exchange is getting bigger too. Using Exchange MEXC without KYC can also be helpful for those who don't want to do KYC, but to enjoy the full features, they must use KYC.
Apply KYC is the personal right of every user, if you want to remain anonymous then it's fine, but security can't be fully activated. Other major exchanges that don't have to use KYC are Binance, Bybit, PrimeXBT etc.
