I recently ordered a 50GH/s unit that I would have (optimistically) wanted it to pay for itself in 3 months (delivery date November). It would appear now, with projections and the almost 50% increase in difficulty recently, that the trend for a 50%+ increase will continue. Especially with the time solving/confirming dropping from 10min to 5min.
It would appear that I won't ever even break even with this unit that I pre-ordered.
How accurate are the predictions that the difficulty will be at 178mil by November 2013?
I ordered from BFL 11 months ago and still nothing! The chances or you getting this device in time to make easy money are nil to 0 and the chance of a steady income are also limited!
BFL are finished as a company due to this as any future releases of EQ will be avoided by the BTC community.
During the gold rush the only people that got rich were the guys selling the shovels !
bitcoin is becoming only for the rich and elite.
