Are u sure u receive 12 coins daily ? That's great coz I don't get those many coins even though I have way more then 100 coins sitting in my wallet.
I downloaded the qt wallet and had 300 coins as of 7th March but till date I have just received 3.2 coins in total
So I really fail to understand how you get 12 coins daily.
Either something is wrong or u are not giving correct information .

Make 10 recieving address and put 10 coins in each recieving address and update me in a week that is there any increase or not.

Does anyone know where can i find more info about the coin...like total supply and current circulation, is it purely POS or POW also??
