So I've been getting caught up on the theory of Bitcoin lately, and even made a moderate investment in a competing cryptocoin. My question though to those who know the space well is:
What would happen if a government were to adopt cryptocurrencies, but just go ahead with their own version. (Doesn't seem hard to invent them: looks like there are literally hundreds of variants out there.) Or maybe adopt an existing one, but hard fork the blockchain, so as to avoid the "founders" of the coin collecting the fees on all global transactions or give early adopter an advantages?
Seems something like that would actually crash the price.


Don't think it would. The invention of Bitcoin was to be able to exchange currency anonymously. How could you do it anonymously if the government controlled it? Especially a currency that is digital which would be the easiest of all currencies to track?
