PMs have been around for millennia, are deemed a safe investment by governments, banks, financial gurus, and the mass media, and yet...

...none of the ignorant masses around me that I know (e.g., friends, family, colleagues, etc.) even OWN any investment gold, silver, etc.

So if they won't, or can't afford to, purchase PMs, then what makes us believe that they would invest in Bitcoin?

The same rule apply, I think.
