Could you share your numbers, Xian? I'm very curious about them.
Admittedly, I suck at math, so it's quite possible I'm off my a couple weeks with my ROI estimates.
The 120 day figure is based on my current extrapolations, considering that my existing, paid-for operation, already brings in x BTC per pay, I'm going to be getting x + ~1 BTC more per day for the next little while just with these additional ASICs.
I hope you can appreciate me being intentionally vague.
Maybe you are not THAT off in your ROI estimates if the ebay post announcing this setup (using your picture) keeps going higher ( and IF it's your post anyways
)
