Apparently not enough.  The ridiculous fear-mongering leveraging the shallow depth of most people's conception of reality in a transparent attempt to artificially inflate Bitcoin at the expense of PMs is a pattern seen in various semi-notorious and/or semi-desperate scammers over the years.  Cypherdoc (aka, Dr. Lowelife) springs to mind.

Perhaps I'll re-visit this thread to flesh things out, but the short story is:  Bitcoin and PM's are effectively the same thing with some modestly different and potentially symbiotic strengths and weaknesses.  In anything approaching a bonafide 'collapse scenario', it would behoove one to have command of both.  In a genuine collapse it could be life and death.
