re. "ROI times"

A few months ago I looked at investing in a mining rig. I put all the numbers into one of those mining calculators. The thing which changed my mind was the difficulty factor. Take a close look at the difficulty chart. Of course what I didn't consider was the increase in $BTC price but who knew? :-) $GBTC.
