If someone think that's a scam or you can't earn there anything and only loose your btc - sry but you are losers Why I think that? If you can earn there 0.5 BTC per few hours and don't do anything you will be knew this And of course I still reinvested there. I guess its can work for few days so just do what you think is good for you

My rig maybe aren't so awesome (2x 7970) but after a month with it in my room I had enough. So - I moved it to my balkony As you can see it has very good air conditioning there (outside temps are 0°C to 10°C) and the most important - I have so blissful silence in my house
