Would a fair estimate be 200 active FPGA mining boards exist today and that would be about 20 gh/s?
If so they do represent a tiny fraction of the mining power today and their uptake would have to
increase in such a dramatic fashion to even become a blip on a chart.
Don't they do around 100 mh/s?
Wouldn't that be just 2 gh?
100,000,000 x 200= 20,000,000,000
