ROI ~2 years? with 1.6w
Unfortunatelly not, ROI infinity...you can't reach, even not in 1,2 or 100 Year.
Guys, keep in mind they have had the U1s in production for a while. So yes, they are pricey based on today's numbers but if these had come out 3-4 weeks ago I don't think there would be as many complaints. They charged what they thought they needed to charge, and people bought them all. Same with the S1. There's no reason to get bent out of shape about it. I bought 4 S1s and paid 4.25 BTC each (4.2 on the last). My first one was the equivalent of $4500 in USD. My last was $2700 because of the fluctuation in BTC prices. So when they sell to us based on BTC prices they are taking a currency hit too. They have to pay their bills, their workers, etc; and I doubt those guys are taking BTC.
Maybe you missunderstand, how this business work. 1 Chip cost the factory lesser then 4-5USD. 1 USB printed board assembly about 1.5USD (maximum, depend on the quantity much lesser). Calculate, and you will see the complete price is per item about 6 or 7USD. A sale price of 60USD each item right now (depend on the "low" exchange rate) bring them 1000% profit, at least.
And, they don't have to pay for any "worker" or what you guess. The printed board assembly price is an all inclusive price from outsourcing factory. There are alot in China. Bitmain just need to calculate the develope time for a handful guys, the production can be outsourced.
