Maybe I should be thankful this happened before I had a chance to deposit.
I'm on everyday without a hitch.
Nevertheless, go with your instincts and critical thinking.
I move a number of coins through Poloniex. They have always been wonderful coin wise (minus the time they lost 10% to a hack.)
Their troll box has pretty gay rules, but wut evs.
Better places to trade BTC/LTC, but Polo is the shit for Huntercoin and Clamcoin.
