pretty sure they gambled with the users money while the price was raising and made a nice amount of money through that... yet now that the bubble did burst they face the problem that their coin is only worth half of what it should be.. so they have to take orders to pay older orders..
I dont have proof but this is the only reason i can think of why all of a sudden they have liquidity problems and deny people (like me) the money they should have got a week ago...
If someone has a better reason for this i'd be happy to hear it..
