And it's gone! 511M difficulty... my mining rig is now completely useless...
I know what you mean, dude...
I did the mistake of pre-ordering from BFL in August 2012.. just a SC Single with 60Gh/s, soon to be worthless.
Beats out my 8 Block Erupters...I'll take it from you when you think it's worthless, or give you a little bit of btc so you don't eat all of it...I'd love to have 60 GH/s rather than 2.673GH/s...
