You like it or not, you need to verify yourself. Basic accounts won't work with them anymore and your account must be enhanced account and that's it. Biitrex account is the best trading platform and so I have nothing against with their new policies if it would mean more security for its users.
I have a basic account with them before and it works perfectly being able to withdraw but due to their new policy not allowing withdrawal without verification then there are many traders whose funds were trapped in there and some are unlucky because they use a different name that's why they can't be verified. Luckily for me, I don't have any funds left before they implement that but I am planning to deposit again but will verify first before depositing so that all will go smoothly. The coins that I want to trade are in there and they have high volume as well that's why I decided to go back.
