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 .
