Binance KYC is the best here. It's almost instant as long as requirements are met. KYC verification isn't also compulsory, it's only needed for increasing daily limit and withdrawals of fiats
well I first learned about this exchange binance from Airdrop which I worked on for a very long time and at that time to get the reward I had to complete KYC, and well it was very fast and smooth and until now I still use it because I think it suits me personally
I didn't do KYC, daily limits is too high anyway, my deposits and withdrawals are much lower than the daily limit is. It's not
compulsory, which is a good thing, but for traders with big capitals it would be not so big deal to do KYC, Binance is reputable
exchange, and they will not sell private information of their traders.
It's one of the best exchanges, and I didn't see a bad review about Binance! That speaks for itself.
