Each time when ZEC price surges, Polo will disable wallet. I suspect they are using the ZEC coins in the users account to short, since some users are holding their coins. Polo sell it at high price and buy back to return to users.
Zec started looking to break the resistance at 0.040 yesterday evening and today morning it finally did, what happened? Poloniex shut the wallet again! wtf? i cant wait until I make my money back and be out of poloniex for good! at this point the only reason i would use it is to convert pascalcoin to btc. such BS.
