Had perfect withdrawels recently there, not sure about deposits, but they seem to have their stuff in order.
Yep, i can recommend Bittrex too, never failed me. At first, i had to get used to their site, but then never looked back. Poloniex, on the other hand, well, thats a long story ! I think they are just there to annoy us.
By annoying i mean 25000 USD in my case. You have no idea what i´m going through. When i wrote to Bittrex: Problem solved. When i wrote to Polo: "Nada".
I've backed away from Polo too, though it probably has more to do with them delisting one of my favorite coins than anything else. But, there have been those weird indicators that have made me concerned. Anyway, if I want to trade on Polo again I'd need to create a whole new account, because Polo is the *other* exchange that seems unable to change profile email addresses. SpectroCoin also has that, er, *feature.*
On another note, do you all think we may have found the bottom on XEM?
