What´s wrong with Poloniex ?
Now they disabled all withdrawals for Ethereum.
It´s time to transfer all your coins to your own Wallets or to other Exchanges before they close there whole business.
I bet a real big, bad Rip-Off is ongoing.
Probably its because a lot of traders had been withdrawing their Ethereum coins, and maybe they didn't expect a lot to be withdrawing all their Ethereum coins most especially of its price increasing. But a lot have been complaining about Poloniex lately and I'm beginning to worry too.
