I've been wanting to build a burstcoin rig for a while but have always had too many hurdles to clear. Since I was looking into it again, I decided to make a very simple calculator. I made a few rigid assumptions for a simple and quick answer and used a spreadsheet to do the math just to get an idea.
Assume:
-price of burst is always 0.00000345 BTC
-using burstcoincalculator.com, I calculated for a 6TB harddrive, which I found on Amazon for $152 (rounding to $155)
-electricity is $0.10/KWh
At least at first glance one could see, all things constant, it seems worth it. Thoughout the year you might be able to pay for your rig several times over!!
4 month ROI??? and paying on the order of $8/year/drive in electricity!
See for yourself:
