Updates to come. I am guessing it may be another hack or bug exploit.
I really hope they aren't cutting and running with the returned money.
UPDATE: I can now access my dashboard, and the price of BCC is back to up where is was before the temporary crash! Hopefully they will release a statement explaining what went on and how they will prevent it in the future. Very concerning from a cyber security setpoint.
Second UPDATE: Its back down again.
