Poloniex has somehow always been my main source of trading. But after reading and acknowledging this I just might shift to Bitrex
Poloniex had the potential to grow tremendously in the forthcoming years, but they have wasted that with their idiotic behavior. Bittrex is a great alternative, and generates more volume.
What do you think about Bitfinex?
Oh, I would never ever advice anyone to make use of that exchange after everything they have put their customers through. I find it mind boggling that this exchange actually managed to gain back its leading position in terms of USD trading. Everything related to the "hack" they suffered from stinks big time, and that's what a lot people were thinking as well initially. For whatever reason, at the moment Bitfinex cleared its debt, people changed their rightfully justified hostile attitude to one that is the complete opposite - this exchange suddenly became legit again in the eyes of the people, and the volumes of this exchange started to pick up again.
