Absolutely davidc2 - anybody who invests their money in something not necessarily 'blue-chip', and especially in a pre-income phase biotech or nonotech who doesn't question what the management is doing and whether (or not) they are setting milestones and reaching them on something close to schedule is being foolish.
I try not to be foolish as I generally don't have money to burn.
Healthy skepticism is a good thing. Having contingency plans for if things look like they are starting to go to pot is smart investing.
We've crossed paths in another stock and anothe board here - and there is at least one other company I have played in nanotech where I have bailed out after a couple of years of holding because it became obvious that management was either completely incompetent, or was just into playing games to make themselves money at the expense of the company & shareholders.
I don't see NNVC going bad in the long term. Just too much upside with very little downside (in the long term) IMO
