I am trading on binance right now but I often use bittrex as well which helps me out a lot on bigger volumes in some of the obscure coins out there and not existing on binance. I just happened to have investments there but my idea is to actually get them to profit and sell and send that money over at binance as well.

I am not sure if it is a sane idea to put all of your crypto in one exchange because it creates a great risk and in crypto you can't get any more risk since crypto itself is very risky but binance has been doing and handling hacking type of stuff for a long time and they have never upset the customer not even once so I kinda trust them with it. So binance alone in the future but bittrex a bit for these days.
