In the 2 weeks I've had my machines running, they have made back more than 1/3rd my origonal
$3897.60 x 3(saturns) = $11,692.80
I've earned 22 BTC x XBT(198) = $4,356.00
which is over 37% of the original purchase price, plus shipping.
(not to mention the 63 Namecoin I also earned)
I have no doubt they will reach ROI, and beyond...
Thank-You KNC
Are you also selling your BTC for fiat? If not, to get a completely honest answer you should be doing your calcs in what you would have paid in BTC when you ordered. BTC has appreciated significantly against the USD since you would have ordered.
I even used the xbt price, when I can still sell @ Gox!
So, stick that in your pipe, and smoke it!
I actually plan on holding my BTC for $2,000.00/btc hehe
But yeah... I see what you're gettin' at...
Just another parasite in it for the profit.
