Curiosity asks me to re-try your platform, just giving it another feel to get around your interface, and I reached the second step where I have to put the fund I wanted to exchange into an address (image below). I checked that the address is new and unused, am I understand correctly that the address is disposable and one-time-use only? How is the address generated? Or will it be the user's fixed address whenever they wanted to do the transaction with the same exchange (I randomly selected changelly for this trial) with the same pair? I have to say that I've never use changelly (or heard of them before), but I took a brief glance at their site and they're a CEX? Isn't there suppose to be a fixed address for each account on a CEX?
