My LS paid for itself.
You came out better than most.
Amen on that. I paid 15 BTC for my Jalapeno and bought the $100 2 GH upgrade. Since it was delivered in June, it has earned 7 BTC running 24/7/365.
Purchase price in BTC: 15, plus the $100 upgrade
Purchase price equivalent in $ (at that time): $365
Purchase price equivalent in $ (today, BTC=$330): $5000
Payback equivalent in $ (today, BTC=330): $2300
Looking at it from a $ standpoint, I did very well.
Looking at it from a BTC standpoint, I lost half my investment.
I doubt BFL will be calling me for a testimonial. My Paypal chargebacks for the last two orders have just been finalized and the BFL site shows status as "canceled" (sic).
Rather than saying "Looking at it from a $ standpoint" say "When I include the appreciation of BTC in USD terms"
Most miners lump in BTC appreciation and include that as profit, when in fact that obscures whether or not your mining operation is a loss-maker.
A few ASIC devices have earned more BTC than was spent on them, but I don't think there are any BFL Singles that have.
