Idk. Open ledger sounds quite complicated tbh. But I've been hearing so many good things about them that I actually want to give them a try.
I hope you don't have a lot of funds locked away on poloniex though! I have about 200 SBD locked up on bittrex too because they refuse to verify me. Bought them at $0.9 through eth and I just want to withdraw them now.... Doubt that's gonna happen so I've basically given up on those funds :/
