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.

Literally zero ownership.

Ignorant masses in most cases just want to remain ignorant to justify their not investing, period.

They would rather moan about being poor, than to actually take action to do something about it.

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

The same rules apply, I think.

Because investing is hard, requires parting with money they barely have (and that they would rather spend elsewhere), and requires taking risks.
