Don't know if Crex24 is any good, doesn't look like it, there's not much liquidity, Ogre is much better imo. Anyway I won't be using them since I'm not planning to buy or sell, I'll just keep mining, but please do not consider a listing on craptopia in the future.
Crex24 has similar daily volume with TradeOgre, i believe community shows maturity when keeps this thing going forward. Bigger exchanges will come in the future and the price will no longer be the bargain that is today.
