I have gotten payouts, i upgraded to v 1.1 and it has payed for itself like 5x so, its free if u want a few free .005 btc every few weeks (minimum withdraw is .005 and it takes ahwhile to get there, u get 40 sat a minute for free) , if u upgrade u get alot more.
A site that pays 40 sat a minute without doing anything, there are 60 minutes in one hour and 24 hours in one day, so let me do the math:
60 x 24 = 1440
1440 x 40 = 57600
So, you will get 57600 satoshis a day which is around $1.4, without doing anything. Yeah, i really believe that (lol).
