I think the price volatility was a mixture of ex-WHL shareholders hanging onto the shares they received in QFY's reverse-takeover of QFY liquidating what they managed to salvage from the collapse of WHL, as well as quite a few investors that got in early subsequent to QFY's launch who weren't experienced in how long it takes to get a technology start-up off the ground and the risk involved.

It remains high-risk.  It can take years to gain market traction and the capital pool isn't large.  It is neither easy nor cheap to gain that market traction, and many fail attempting to do so.  That said, the core product is sound and is aligned with the emerging leaders in the field of automation (Amazon, etc), so it's in with a good chance.  If you run the numbers based on reasonable estimates you'll note that they'll need to be shipping solid volumes - or licensing to those that do - to see any substantial 'grounded' share price growth.  Buying in at the current share price, assuming that it's part of your higher risk portfolio allocation, may just pay off quite nicely over a good five years.  It's a bet, but it's a better bet than a lot of other tech start-ups.  At this price, well worth it.
