i have an idea. to start, let me ask you a question. the entire bitcoin network is supported and kept alive by enormous hashpower, is that right? hashpower mostly equals electricity. so we should trade coal/uranium (this one probably not thanks to some unwanted waves) as a form of electricity for bitcoin and PoW coins, thus making the pos coins very cheap and used, because all you need to mantain network is a lot of rpi and a wallet. we might aswell turn on enormous EMP, and get some mining facilities of bitcoin down this however would be only fictional and probably illegal to fly a plane over a village and shoot emp from it, not even nice, of course. but what about the first one. to mine coins you need rig, 10% from the cost of parts you pay to distributor/reseller, then you need to set it up etc. why not buy it with coal, the entire rigs and such thing could become worthless in future. thanks for reading my hypothesis
