Are you still mining BTC with GPU?
Your point about the power of the network is quite interesting. I recall reading somewhere that the BTC network also uses the equivalent of a nuclear power plant in energy. Seems wasteful at first glance, but no doubt even more power is used keeping online payment/ card systems up & running. Hopefully the ASIC boom will reduce the need for power in the future as well
Well, I had been mining altcoins but since I got the block erupters Ive been pointing all my miners to btc. I realize not the most profitable at the moment. Probably able to payoff one of the block erupters in twoish weeks mining btc.
Yeah, I think that same article said that the btc network uses either 200k in power an hour or a day..cant remember, but probably an hour. I think its only wasteful in the sense that its not accomplishing anything for a "greater good". Sure creating a decentralized currency is a good thing no doubt. But for the benefit of man kind, I think not. More for the benefit of out wallets.
