I do not mind if some of them are seen as a bit risky. So long as there are not an obvious scam. I do not want to trade with a huge amount, so i would not mind to lose my "investment".
You can throw some names at me and if you had some experience (bad or good) with them. I also do not mind if i end up with more then one exchange using.
I obviously don't know all the exchanges. I worked mostly with Poloniex and Bittrex. They have big volumes, but no ICO/small coins.
The exchanges you may need are Yobit, Bleutrade, Cryptopia, Nova exchange and so on. But I have no experience with, I used them too rarely to tell much. They handle new coins, they handle ICOs, but they may have very low volumes too. I advise you to ask more opinions and also do some research by yourself too.
