I feel like with the recent annoucments and news, the chance is pretty high. A lot of advanced economies like US and China have started slowing down in economic growth and this can easily be attributed to the lack of room to grow, which is why crypto-currencies and blockchain technology look like the next thing where countries are able to revolutionize and Excel at.
There is a big possibility that the adoption of blockchain will surely make the digital currency for their own country. Same as the digital bank system owned by the government, so cryptocurrency created by the government will only apply in that country. In global transactions bitcoin or altcoin are still superior, and become the best choice, this will not threaten the presence of cryptocurrency that exists today.
Yes I am also very sure they will make their own Crypto to facilitate us in making transactions in the online world. Our government is actually still "ashamed" to use Blockchain technology because this Blockchain technology is something that can not be separated from the world of Bitcoin while they are very afraid of Bitcoin.
I wouldn't classify it as them being ashamed, it more then not being able to control Bitcoin and other decentralised crypto-currencies, whilst their own coins are easy to manipulate.
It's been announced countries like Korea, China and Japan are already looking at making their own crypto-currencies and some of them are in development.
