We’re at 400 petahashes today, and increasing at about 75% a month.
Oh, and supposedly there is 50 TH in raw chips from avalon locked up in customs, which will probably come online sometime in the next 6 weeks, allowing for customs mess and then getting the chips attached to PCBs once they get out.
I think we’ll see a petahash in late october. I’m going to call it October 20, 2013 just to see how close I can get.
In the works is a post about trading difficulty futures on icbit.se.
Anybody who owns mining stock (such as asicminer, or AMC) should be keeping an eye on this.
UPDATE: 1 PH happened today, September 15. Way earlier than I thought.
