Bittrex, Hit-Btc, BitZ, Coinbene, Okex, Huobi, bithumb. all legit exchanges with known coins in their market. IDAX has some weird coins on their side, besides EOS and ETH. Their hole volume comes mostly from one coin. Don´t know why you would go with IDAX in the first place if you have the funding for a good exchange. You just need one good at the start, more will come down the road.
I totaly agree'', iv`e seen far weaker projects hitting two exchanges in less of a time frame, the community showed great support & patience and moreover the project has more substance than 50% of the top 100...after all that, to launch on such a weak exchange is mind boggeling..
I hope to see @ least a banner add on Coin Market Cap..well worth the cost....
