Congratulations! After wasting 200$ worth of electricity, 2 weeks of computing power, and brinking on the edge of insanity, you can get ONE penny, in only 5 years, you could have a mousepad worth two dollars!
This is like getpaidto, only automated and it wastes tons of energy.
Also considering that site uses a fake pseudo nonofficial internet currency, instead of a secure, governed currency, I can somehow see it open to exploits. And that's actually pretty concerning considering they're selling real, physical items.
