Im a BC'er, but from an outsider perspective, I HIGHLY DOUBT DC will crash, at least at for a good while.HOLD on DRK, im sure it will go back up. there is too much development atm for it to go down for a bit.
IF you dont feel comfortable, invest a percentage of what you hold there, and spread it into another investment(s).
for reason of conflict of interest, I will not suggest what to go into lol if you decide to.
good luck!
