Q:
You said 20% interest per year, do I have to wait 1 year to get the PoS interest?
A:
No. PoS blocks will be generated after you hold some coins in your wallet for certain period of time. For MintCoin the minimum requirement is 20 days. If you move around the coins (for example send to other wallet and then send back), the time will reset for those moved.
http://mintcoin.cc/faq/Yeah, between the front page of this thread and the new website most questions have been answered except this one:
So will PoS be implemented in 2 days? That would be 20 days after launch. Or will the first 20 day period start after the mining phase ends?
