Bitcoin will not become the unit-of-account without the blessing of the government, because it has no distribution scale
Bitcoin is the tech that allows a knew form of "government" in a decentralized way...
My statement holds, because Bitcoin (and Monero and all the others) are not decentralized. Adoption for use as a currency (without being an investor) is
almost non-existent.
The idea (PoW) was noble and idealistic, but the overall design sucks.
