qTrade has been around for maybe 2 years and they have been trying to get on CMC for a while, I think it is because they are lacking volume. They are a small operation with not much liquidity. You can go vet them on Twitter. But I agree that because of that, they are probably not great for newbies. Anyway, I am genuinely curious if there are other more developer focused exchanges because I have not seen any.
I have experienced trading QTRADE many times because of Idena and I can prove and give a testimonial that it is an honest exchange, far better than all those exchanges that launch ICO that only turn into scam projects.
I hope they can continue to list good coins and tokens and they keep up their reputation, they have a long way to go but they will arrive.
