Now a days id verification or KYC is mandatory in every major exchange, so i happen to ignore all big exchanges whether it is bittrex or binance. I prefer decentralized exchange, though the volume is less there but i love them as i dont have any privacy concerns there.
yes, and I think this is a natural thing. however, there are still some exchangers who do not need to verify ID, or KYC to conduct low transactions. most exchangers also like that. well, this is an advantage for me who rarely make big transactions.
