Seems that Primedice are having some bad memories from the hufflepuff incident and the admin want to fully investigate the rolls before the release of the customer funds. Bitcoin price have dropped a lot during this few days, wonder how much is the bonus primedice are going to offer to the player if the investigation is done and the rolls are all fair.
With the huge bankroll of primedice, they will definitely payout the 4 BTC to the player after the investigation if it proven fairly won on the rolls, keep us on updates

I think they have the right to investigate anything they want. The hufflepuff robbed them big and they don't want something like that to repeat. But I have a feeling that this guy won his 4 BTC fairly and they will pay him eventually.
