I've been using coinbase and cex.io recently. They have too much of a fee in my opinion. Anyone use gdax, or what does everyone use?
i like to use bittrex wallet it is secure and easy to use. but polonix had more disadvantages so don't use it. once you have to check and use this type of wallet. generally most of the people like to use this wallets because bittrex features are really amazing. since having withdraw problem and security problem in polonix but in the bittrex has no like that problems. so try to use maximum bittrex site good for usage.
