Primedice is paying out everythign over 0.1 BTC manually for security measures. I don't know how long you've been waiting. But throwing out a "they scammed" me flag is a pretty hard accusation.
Mirela told you whats up.. why wouldn't you just wait like everyone else does? Or do you see some topics that lately called out for a scam? Don't sharpshoot too far. This measure is to protect you, the community, the staff and of course the owners.
Primedice is definitely not a scam...
