I wrote you a long response vlad but I'll leave it for another day , you will likely understand more later if you think about this .
Sufficed to say , I'll say this .
1.Government as such is not the problem they are least of many problems.
2. Government will never own cryptocurrency .
You will work this equation out.
I think you need to do a little research behind the fed and who actually owns the fed to have an idea who's gonna own digital cash when it becomes the mainstream deal they're hoping for.
FYI: the fed's 99 year contract to print dollars just expired so its pretty convenient that Bitcoin Just happened to be here and to go buck wild all of a sudden for no obvious reason.
If you understand what the fed really is and who owns the fed and that they will never give up the power to own and print all the currencies of the world you will then, undoubtedly understand what will, without a doubt, happen to any new currency in this world or any new future global currency they've been trying to push since the 1970's.
I do have an advantage in that I had to learn a lot of this in Economics so I assume people know these things when many do not. But the information is out there on youtube and the Internet and its all documented, historic facts so anyone can figure this out. While you're checking out the fed check out when they were given the power to print money relative to when gold was criminalized and also read about how they passed the bill giving the fed the power over our money - interesting date and time to hold a special session in congress for something so important.
It will give you an idea of what this government is capable of doing and keep in mind, by most standards, America was and still is one of the good guys. The truth is Pretty scary. When you first learn about it you simply can't believe it but it's right there in black and white - the history they never taught us in school. And now it's getting ready to repeat and 95% have no idea what happened 90-99 years ago so they'll have no idea what's coming now.
