the main strength of cryptocurrencies is their decentralization. No digital asset that is controlled by the authorities can be called a cryptocurrency. Based on this, there is no difference between a digital yuan built on a blockchain and a simple fiat yuan. based on this, the Chinese digital yuan will not make a small revolution in the cryptocurrency market and in the world in general, as many expect.
No one from this industry will embraced the idea of making a centralized governance towards cryptocurrency, like what you have mentioned there's no differences between fiat Yuan and the digital base Yuan,
same aspects that they are both controlled by china's governance, this adoptions will remove the intentions of having free of interferance from any government form system.
We should continue to stay with decentralizations as it was the very reason of this system.
