You should watch the show Mr Robot. In the season 2 it goes full crypto, and there is a way of governments vs Bitcoin. The script predicts what I was predicting myself, and that is, a future in which governments want to control 100% what you do with no possible notions anymore for privacy, except they didn't count with bitcoin delivering financial freedom.
They have a cryptocurrency (developed by E Corp) that is closed source and they control everything and they hate Bitcoin since it bursted their Orwellian dream's bubble.
Whoa.. Mr.Robot seems to be the new fap - material

To the OP, countries have already started to create their own coins but who gives a shit. It will never come close to bitcoin due to obvious reasons. There ain't no shit to worry about.
