Which of these two exchange services do you use and why?
OP you should've added a poll
Bittrex is a reliable exchange with decent support, and I was using it a lot in the past for daily trading, but I prefer Poloniex for two simple reasons.
First of all, it has bigger volume and secondly (this is the most important for me) somehow I feel that my money is safer in Polo than any other exchange.
I think that might be because basically, Poloniex didnt encounter any serious problems through their history since launch, and I feel the same with my money on poloniex.
When i was comparing Bittrex to Poloniex, I have found out that I really prefer the user interface we have on bittrex, and the overall trading platform.
It is more transparent for me, and not laggy- when I have some strange backlogs on Poloniex sometimes, which is extremely annoying for me.
But I need to say that I still would choose Poloniex, because this cryptocurrency exchange has really higher volume ( highest among the exchanges ) and I can also do margin trading/loaning there, which is not available on bittrex.
