POS minimum coin age is seven days. So if you put xDMD in ur wallet, after 7 days you will begin to have a chance to mint new coins. I am no expert on the mechanics of staking/minting, but (rough description) it is determined by how many and how long an individual pile of coins has been in ur wallet. Actual time staking varies but minting value increases as time staked increases.
In my experience, 100DMD staked for 30 days should pay out within 24-48hrs of running wallet.
More details are available throughout this thread.

I have my coins for about a month and my wallet shows , that I earn a reward in a 36 days. Is it correct?
