I'm in the process of buying a Modminer Quad, because
A) It fit's my price range
B) Super cool looking
C) It will still be profitable for a few more months
D) I have free electricity
I don't know if you really understand this, but do you know that you "might" make about 7 bitcoins over the course of those couple of months. Totally not worth it unless you only pay about $120 for it. Just Sayin'
I'm not mining for profit. I like the whole idea, and I'll be helping out the network. TBH, I haven't seen any proof of ASICs coming out, so who knows - it may be more than a few months. And it may be profitable since the price of BTC can increase.
I'm with you. I used to do distributed.net back when they were cracking RC5, then folding at home. Now I mine bitcoins. The other stuff I did for free for science. This I do to help the concept, the fact I can make some small amount of money is a plus. I even run a Tor exit node to provide another service I think is needed, aside from helping the Bitcoin network.
