Once the DashMaster is about to ROI, it will be obsolete with that high price.
What is the ROI right now for the DashMaster?
Currently i have it as sub 75 days.
How did you come up with that number ?
If we are very positive and assume that the difficulty will stay as it is and calculate with todays value we have:
$32 Profit per day (given 10 cents electricty-rate)
Now let's say you bought that thing for the cheaper price of 8.500 USD
In that fantasy-scenario you would need 265 days to ROI.
Remember: for that to come true you must also become a super-villian who destroys all asic-producers AND all miners currently being shipped or sitting on ebay.
