Credits should be applied within 30 hours from this post, some will get theirs tonight others tomorrow.
A lot of posters were below the minimum activity but it looks like there are 300 eligible so 3BTC will be credited.
How to claim the BTC
1. Post your Primedice username in this thread
2. Your account will be automatically credited in 72 hours from this post
So, NOT automatic and NOT within 72 hours after all. Keep "building" trust in the community.
