Yea, that sounds about right.....NOT FREE......then if you do not meet the minimum daily trade volume, they delist you....
Cryptopia seems to be getting better all the time, am very happy for them, and consider them a great asset.
It would be great to see GUN listed on Bittrex, but what's really needed is some use and volume.
BTW, I have picked up my pace a little, and have been spreading some GUN paper wallets around.
