I havent used poloniex and bittrexx in a WHILE because of this very thing, especially since my bittrex was hacked into....twice...
but it seems like a few exchanges are having these lock up issues at the moment, its because of the massive panic selling thats going on at the moment
Someone hacked into your bittrex twice? That's scary. Think about hiring some security advisor to get thing sorted out. Few hours of trainings and you would be much safer.
Yeah it could be that maybe my password was just too short? im not even sure, but i kept on getting the message that a successful account login had happened and i was like....well... i was definitely asleep during that time, so it wasnt me, and then it happened again 2 days after so it was a bit of a shock
