Has iBeLink made their order numbers public somewhere?
No, they've been very closed about that - but so have ALL of the other miner manufacturers for ANY ASIC-based mining machines.
The iBeLinks aren't going to achieve ROI in 2 months - it's already been almost that long since they were sold out and they don't appear to have shipped a significant number of them yet (and if they have shipped any it was to the folks that ordered back in May or so when they first went on pre-order).
They *might* achieve ROI in 2 months of OPERATION if they start arriving before the end of the July, but when it takes someone 2-3 months to even GET the miner that's NOT a "2 month ROI".
They're also going to bump the total network hashrate up a LOT before Bitmain or Innosilicon even START shipping the D3 / A5 at all, which will make it take longer for THOSE miners to achieve ROI - and THOSE miners are looking at 2 months or more of "pre-order delay" before THEY start shipping, presuming Bitmain and Innosilicon meet their announced shipping dates (Bitmain has a pretty good record there, Innosilicon is mixed).
Thanks for your feedback.
I am expecting mine to arrive by 10th August so lets hope i make my ROI in 1 t 2 months and that is very much possible based on scneario that Innosillicon monsters and Bitmain's D3 won't be shipping before October 1st.
And in worst case the ROI will be in 3 months, but lets hope for best i am hoping for 1.5 month ROI period
