Hi
I saw AdEX is available Bittrex.com but I am new to the exchange. So far I have always used coin base for trading. Can you buy ADX by transferring $ from the Coinbase USD wallet to the USDT wallet in bittrexx?
You should check with exchange staff. I think there will not be a problem.
It's better to buy USDT in Coinbase then transfer it to Bittrex.
