Let me add a third concept which, to me, is a much more useful feature (as I wrote in a sister thread): a store of value for people whose governments like to control the money flow, dilute savings in the single available local fiat currency and confiscate savings calling it a money reform. Which, sadly, is a large part of the world.

Value oscillating against some golden reference by a factor of 4? Many will likely take that if it means avoiding their own government shenanigans. I saw a currency reform which turned savings to zero. My parents lived through two such devaluations. As did my grandparents. Buying dollars or another hard currency, if found, meant prison. In this setup a permissionless, anonymous store of value, warts and all, is very valuable.
