Bitcoin Commodity Exchange. It is the modern way to mine bitcoin by hashing in the cloud. You can trade hashes in their market, or hold on to them and let them mine bitcoin for you. The real money can come from trading if you do it right, always try to buy low and sell high. If you put in an order to sell, your gh/s will keep mining until it's sold. My strategy is to reinvest all of my profit and buy more hashing power, along with a little trading if I can find a good opportunity. http://axallbitcoin.blogspot.com/
