Hopefully we can land Cryptopia, but I know they charge a lot. They were charging $PIEX half a million $DOT's or something to that nature to list them.
Cryptopia will be soon, The devteam is working hard to make it happen lets just wait and be patience while they are working on the background.
Cryptopia is OK, also coinexchange.io is a good exchange i know is like 1 BTC to list a coin there on coinexchange.
