This is a game that has been around for quite some time now and there are debates as to whether it has turned scam or just simply into a game where you need to reach a ridiculous amount of BTC before being able to withdraw, however it seems to have undergone some form of reboot as the sites new withdrawal limit is as low as 564000 satoshi whih is paid out every friday, I played it till I reached the minimum withdrawal limit last week and am happy to announce that the site has begun top pay once again so come over check it out and see if you can earn a lot of btc from it :)
