Ive been hearing that there are issues from not only Poloniex but also from Coinbase at the moment as well. People tried to withdraw money during the ether price crash and they were told that the "service was unavailable" .... things are starting to get a little fishy with some of these companies.
Not only cant they handle when a price increase happens and people join on board the crypto train, but they also seem to have a hard time dealing with prices going down and people wanting to get their money back
I hope this isn't another case of ETH becoming ETC2 and they revitalize a new ETH3
Coinbase is always doing this when they are uncertain of things. Remember their own exchange is GDAX, so things are linked together and they batten the hatches when a storm approaches. Unprofessional? maybe! Safe? Probably!
