Do you plan to enlist any coin? If yes, it is the worst idea, IMHO. I am not a tech guy but it seems, if you enlist a coin with bad codes or back door or something, there will chance of hacking. I hope you know what you are doing. I have a bad experience from coinsmarket exchange. I think they are almost dead or at least facing network issue.
But GIO is moving forward and I am pretty excited about it
