Sorry for the delayed response, holidays have been quite busy. I have not used Blocktrades, but will add that to the list.

Binance only requires an E-mail. They do have different verification levels, which will affect your withdrawal limit. 2 BTC is for an unverified account. 100BTC for a verified account (send them personal information).

Fees are pretty low and if you hold their BNB coin, you get 50% off trade fees by paying with BNB.
