One question: what do miners produce? Huge amounts of energy is used with mining. I googled it for a while and all I get is how it works, but the best answer I can get for ' what does it do ' is... "Solving math problems". Really? Whose math problems? It it like SETI Folding @ Home? Are universities curing cancer with the help of miners? What is generated, calculated, produced or what service has been offered for the currency they're getting and who pays for it? You can't just generate money out of plain nothing, right? Someone ?
