Using
this calculator, with BTC @ $100, a constant increase in difficulty like we're seeing now, assuming zero shipping and electricity costs, at $55/GH it will take over a year to get a full ROI if hashing is started on the 1st of September.
If you've lost faith in mining or no longer want your hardware for whatever reason, I will buy it off of you in a payment method of your choice (provided I can accommodate) for $55 per gigahash, if you can guarantee delivery before the beginning of next month. Feel free to mine after selling to me for this month, as long as you can guarantee with absolute certainly that I will see the hardware in my hands before the 1st.
My offer drops to $30/GH by September, $17/GH by October, and $10/GH by November, based on similar values as above with delivery guaranteed before the following month.
I am of course aware that people are paying outrageous prices that ensures they never see their full ROI, but nonetheless my offer is on the table for those who want a guaranteed sale immediately.
Cheers.
