It may come from many different ideas of electronic payment, online banking or government platform to throughly track their currency in an online application. It reciprocate that meaning of crypto in being decentralised since it's China. But in other country, I hope some government will be open in idea of using blockchain in being desentralized to show the transparency in their government in managing their funds.
I guess that the creation of the coin is just a way to protect their digital currency and noting more, which china is very good at holding on to their power and that is why they have not lost owner for a long time now, and you know that when it comes to chain, they are very fast thinker and whatever they produce is always very useful.
The project will actually be a success because they have the population to see to that, just like Facebook has the population that would ensure that their project is a successful one also, but no matter the project they come up with, even with their popularity, bitcoin will always remain bitcoin because it is the only coin that I see run n decentralization for now.
