Excellent article and I fully agree on your point of Bitcoin is something which you opt-in to. We have seen the various fiat currencies failed over past centuries. In our era, the decline of fiat system started since Richard Nixon took the USD off the gold standard in 1971. Since then, we did not have an alternative currency to fiat and this was finally changed with the invention of Bitcoin.

Not only do I see Bitcoin as a hedge for the failure of fiat currencies, it is also a censorship-resistant way to move value (or money) around the world. This is an increasingly needed service as we see more governments surveillance and censorship on their people.
