Bittrex is the most problematic crypto exchange. It had previously required verification of the identity,
otherwise it would be impossible to withdraw your money.
I understood that bittrex asked for the verification of your identity if you made withdrawals greater than 10 bitcoin, if I am not mistaken.
Yeah, you are mistaken. Bittrex will definitely ask you to do verification even without withdrawing. It is their policy and since they are based in the US, they have to follow the rules. Normally there are some certain limits of verification anyway, but to be able to get as much as that, it is definite for you to do an enhance verification.
I see no problem in all of these, and I do not know why people take it as one, why pick on an exchange when all they require is just simple and if it cannot be followed, there are other ones. I have never had an issue with bittrex and I am sure I ever will.
