Now that the auction is over, may I ask why people would still bid that much for a preorder? I mean it will take a year to get your initial BTC investment back and you have 0 promise that the price will stay as high as it is right now...
its a preorder so you cannot start right now. so take a 4 to 8 weeks delivery time, you make 4 BTC / month which will reduce maybe even half every month.
4BTC / mo
2BTC / mo
1BTC / mo
...
Maybe im not uptodate with the promised delivery times so whats the newest date?
Let's assume the buyer gets his Avalon when we hit a diff of 40 M (double of what it is today) with 85 Gh/s:
The calculation will look like this to him:
BTC/Day: ฿ 1.07 $/Day: $ 116.13
BTC/Wk.: ฿ 7.48 $/Wk.: $ 812.93
BTC/Mo.: ฿ 32.49 $/Mo.: $ 3530.45
BTC/Yr.: ฿ 390.33 $/Yr.: $42417.60
My guess with ever increasing diff ..... that he gets total ROI in 3 to 4 months.
