The amount of miners that will be going offline in the next weeks will likely be HUGE though. It would take a year or more to catch up with something like a 50% drop in hashing power at the little difficulty adjustments that will happen, and in the meantime transaction times will keep going up. I see some serious fluctuations happening in the near future, and that is the last thing that retailers and such want in an exchange medium. It is going to be an interesting ride and I will continue to flesh out the half dozen stories I have sketched out relating to Josh's scam and BTC in general.
If 50% quit today, block times would be 20 minutes long. That wouldn't take a year lol, it would take a month (2x 2 weeks) to readjust. I gotta see what miners I'm going to buy. I'll make a killing using my work's electricity for 6 hours a night (overnight shifts for the win). I literally get paid to sleep 6 of my 8 hour shift and nobody else is there.
