As a fan of both Ron Paul and the cryptos, I really enjoyed his take on Bitcoin. I though he had a pretty good take-
Now, some of the comments in the video clearly didn't understand where Ron was coming from. He is cautiously optimistic, thinks that Bitcoin (or something like it) could take down the dollar, but doesn't want to be a speculator himself.
That makes a lot of sense at his age. Plus, I would bet that Dr. Paul put lots of his assets into gold, or other physical stores of wealth like property. While Bitcoin and many of the other cryptos have risen compared to gold, it's not as dramatic as when comparing it to the inflationary fiat petrodollar.
Myself, I'm more of a crypto speculator.
