I’ve been playing with a bitcoin miner for about two weeks now. I have generated about 0.70 BTC using my laptop’s ATI graphics card. Is BitCoin a scam? Perhaps. But it doesn’t bother me because I am in no way going to put any of my own money into buying bitcoin. I will, however, put my computing power into generation of blocks using a pooled, gpu-accelerated mining technique. I’m treating bitcoin as a game.
