The rumor has friedcat predicting an exahash (1000 petahash) of total network power by the end of 2014. That's a hoover's dam worth of power, on gen 3.

I find that a little hard to swallow.

My understanding is that mining becomes uneconomical on electricity costs alone at the current price, somewhere in the 60-80 petahash range. So I don't think it's realistic to forecast a petahash, unless prices rise over a thousand.

Would friedcat really go out on a limb like this? I bought some more on the rumor, but I'm still skeptical.
