I will quote this up to make people do not read your whole story in there:Then as a test I tried to withdraw a few ripples from my poloniex account to bittrex.
You are lucky, i must say that almost anyone is able to withdraw money from there, a lot of people were saying that poloniex was having a lot of issues about withdrawing money from there.
The same happened to me when a few months ago i was not able to withdraw bitcoin because of the blockchain, i tried to withdraw ethereum and it got through in less than two minutes.
