How much have you made off Bitcoin as you consider yourself such an investment guru.

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.
