Have you thought of this calculation: at what difficulty (at current price) would mining no longer be profitable? At what price (at current difficulty) would mining no longer be profitable?
Peter it seems that it would have to go to around 3 dollars for it to be totally unprofitable. My electricity is pretty cheap here .09 per kw/h. Remember though after the IPO is over, 30% will go back into the company to invest into companies on the GLBSE. If the price goes that low I'm sure the difficulty will plummet also though. As posted before I don't want the mining operation to get more than i can handle (maybe 2 more rigs). I just want to have something stable for people to invest in. Tired of reading threads with people wondering where the owner of the company went. lol
