Me too, Bittrex was great and HitBTC are not very ecosystem friendly aimed mostly at speculators for swapping around between the latest greatest coins without ever withdrawing, not people who want to buy Maid to own it.
The regional (NZ/Aussie) exchanges are Ok but lack liquidity due to limited userbase which will probably not change due to their local focus.
I would love to see a new top ten international exchange list Maid to replace Bittrex. I recently posted news about Bitfinex. Their developers just implimented Omni Protocol (used by MaidSafeCoin) so would probably be open to leveraging all that hard work to list another. Unfortunatly no word yet from the team on that thread though… not sure who is in charge of that department, the very busy @dugcampbell perhaps?
