I think governments will start using blockchain technologies in creating their currencies. A kind of replacement of dollar with a... bitdollar (biteuro, bityen, bitpound etc) 
And it will be a digital dollar, yen, euro and everything. That will be the start of upgrade by technology when it comes to the financial matters of each country. I do believe that we are near to that place, the government just need to realize that there are still people that are computer illiterate but not in America but in some countries.
IF what you are telling is going to happen then i think the value of following this technology will become failed as same thing will happen that each country government will control digital currency also and which wont make it good for it. So i think their wont be another bitcoin and both bitcoin and dollare are different, one is used online and another is used in real life.
I don't think there will be another bitcoin or government controlled crypto. They just don't like decentralization, if you are aware of the microchips that is already being implemented to different countries, that's the start of the upgrade of US and other followers for their money but it's not a crypto, it looks like a credit card or digital cash.
It will not be a "crypto" I guess but they will use the terminology as a digital money. But that's the real thing about centralization, they will make the people believe that centralization is a good thing but in the end that's the reason why they can start to control people. And it's still up to us if we will depend on them, but I believe most of us will stay at crypto / bitcoin.
