It would be great to see REA on Cryptopia, HitBTC or Huobi. It will attract a lot of new investors, as the last two exchanges have a solid image.
Bigger exchanges will be considered once REA competes further listing goals, which are Cryptopia and Livecoin.
Cryptopia is a good and convenient exchange. There is fast deposit / withdrawal of funds, and low fees. Only one minus - low trading volumes for some trading pairs.
