Just cause so many people always ask about minting....
the larger your balance that you keep the more chance you have to Mint coins.
It does not mean that exactly 20 days from getting the coins you will start minting, it means that you have the chance to mint coins
It will average out to be 25% for the first year
here is my transactions showing you the minting process.....I mined in 100K blocks from the pool, and you can see the amount of stake i'm getting as well. You will also see a big 100K stake, cause I had my wallet off for a day or so
