That one has been a great hold of mine (was buying it at .01)... there are those very few, rare OTCs that are indeed worth holding (investing in)... must check out being real with product, revenue-even profit, legit-honest-smart and hard-working CEO...

And how does one check out a 'penny' for all of these traits and make sure they're facts: make sure it's 'current' on OTC Markets... read and understand financial and other filings and PRs (Press Releases) the company discloses... speak with or contact legit third parties that could corroborate what that public company has or discloses... as well as contact the CEO and get answers (I really like conference calls allowing questions following a presentation).

Yeah, I know, sounds like what investors in big blue chips should do and do... ahaha

Wouldn't it be nice if some day, HEXA can be in that league...
