And it's gone! 511M difficulty... my mining rig is now completely useless...
I don't believe it has become completely useless by this increase. It just won't pay for itself maybe.
[edit] If it has really become
completely useless for you, maybe I could find some use for it... :-))) [/edit]
BTW, the increase has been "only" :-) 30.7 % this time.
Block Erupters weren't paying for themselves the last 5 increases. That ship sank long ago.
