Found more info on listing a coin on cryptopia.
https://www.cryptopia.co.nz/Forum/Thread/1484basically you need to pay 2,500,000 DOT to get it considered

everyone complaining about the price...
trading on cryptopia 2,500,000 DOT = 9.5btc
..
don't pay to get added, its a scam as they'll remove you later on and you'd have to pay again.
I don't want to pay, but if we have to, the 1.5 btc fee is doable. Should we wait a week to see if anybody replies with a cheaper offer?
IMHO waiting for a better offer is a good idea. The fee is doable, but seems high given the long and credible history of DevCoin
