Dont ever use Poloniex, I've been waiting ten days for 800 dollars worth of bitcoins to be approved in Poloniex, I've sent dozens of ticket support requests daily, and get automated replies that someone will help, I have also written to their Press department and no reply either. I've posted about this everywhere, it feels like they are trading people's awaiting coins or have put them in storage, there could also be a scam going on between Poloniex and some others, because I am not the only person this has happened to, there are hundreds of cases it seems, they need to be reported and the site should be closed down, this needs to be investigated deeply. https://www.cryptocompare.com/exchanges/poloniex/reviews
