I was looking at my new Butterfly Jalapeños while logging on to my Bitcoin Wallet (My new one as I still haven't found the old one.) and realized how inefficient the Butterfly Jalapeños were. So I started looking up Bitcoin miners. I came across the AntMiner S7 and thought it looked amazing, I also calculated that it would make over $4 USD every day for a total of over $100 every month. I did some more research and could find no problems with it. I was wondering if anyone knew of ANY problems of any kind with the AntMiner S7's. Thanks for the help.
