We did contacted a lot of exchanges, some doesn't list new coins or lists only ERC20 tokens, some didn't answered so far, some are asking too much money, some expressed the interest in listing us.
Also we don't want to get on any exchange out there, just to get listed on more exchanges, no matter what the exchange is as we may end up on a bad exchange, which doesn't update their wallets, have deposit/withdrawals problems or even worst where people loose their money, like it happened with Octaex exchange. But we are working to get listed on other exchanges.
