People actually stopped mining.
I am amazed, how about you guys?
I'm not. I actually personally know three people who got out because Mt.Gox's downtime came at a really bad time for them. They had gotten overexcited -- and then got overextended, spending more on hardware to get into bitcoin than they could really afford. None of the three panicked, but the profit curve for them was such that they couldn't actually stay.
Today, where I live, it went over 100 degrees for the first time this summer. It'll do that many more times. Those rigs in my living room generate a lot of heat. If I actually had to pay extra for my air conditioning those would be a lot less profitable... and I suspect that's slapping a lot of other people as well. I have a local friend trying to talk me into relocating his three mining rigs into my house, because I have better cooling costs -- he's probably going to leave and try to eBay his hardware relatively soon, the cooling costs are going to slap the hell out of him on next month's power bill. That plus the drop after the exchange crisis... he's afraid he'd do worse to stay than he would to leave.
