KYC is needed to increase withdrawals, and also withdrawals with money, yes of course I do not agree if the market uses KYC, if trading is small
There must be restriction, since if you only use small money then it is better not to fill up the KYC form. Binance is a good exchange which dont require you from filling up the KYC form, its good if you choose the right exchange. I think this is mandatory now on some exchanges, just be careful with your identity and money.
