I bought into this a few days ago. I only bought 100 GH/s because I have this feeling that I wont really make anything on it. In fact I would be happy to see just break even in 5yrs. It all depends on the difficulty not increasing drastically I think. This term it doesn't look like it is predicted to be a big increase so I shouldn't see a big drop per day. If we get a few terms with bog increases I may not have any chance to ever make it back. Either way it will be an experience that I will learn from one way or the other.
