You could pick up a history book, and you would learn that gold was almost never used as currency because it was simply too rare, and too valuable for the amounts traded in normal commerce.

It’s pretty simple - just require taxes be paid in Bitcoin and use violence against those who don’t pay. Just like with other revolutionary wars, you pay generals with land and soldiers with the new currency (I.e. Bitcoin). Some of those generals will end up as a dictator or president depending on whether you are able to establish a democracy.
The state will be the ultimate HODLer just as it was with gold.
