Why I'm receiving coins again and again? Tx type: Mined. I've got 6 incoming transactions today. The same amount ~81 coins.
it's the Proof of Stake system, as long as you keep your coin in your wallet you get the interest.
But how come i get stakes for only 0.09 xcoin? I mean... my 4500 xcoins produce only 0.09 coin daily?

4500 * 1% = 45 a year
45 / 365 = 0.12 a day
makes sense...
so you need approx 17 million xcoins to produce 6 transactions of 81 coins daily like this guy here
