In my opinion, CBDC is dangerous for the development of Bitcoin only in a situation where the CBDC of one country is freely convertible into the CBDC of another country. In the absence of disunity and geopolitical tensions, CBDC does pose a significant danger to the first cryptocurrency. In a situation where the world is split, Bitcoin will flourish.
Mankind needs world money, it needs a standard of value. Such world money should be decentralized, because in the conditions of geopolitical fragmentation, countries do not trust each other. And Bitcoin is simply designed to operate in a trustless environment.
Therefore, in the current realities, the chances of Bitcoin becoming the world's reserve currency are very high.
CBDC cannot compete equally with bitcoin because CBDC is a highly centralized currency and can be blocked at any time. To develop CBDC, governments will banish cryptocurrency from their country, as China has done.
I am inclined to believe that the implementation of CBDC will happen faster than bitcoin will become the world's reserve currency, as it may take decades for bitcoin to be recognized as the world's reserve currency.
Right now, we don't know for sure if Chinese people use Bitcoin or not? Is there a black (or gray) market for bitcoin trading in China?
In any case, China is a country with a special mentality. In China, the state completely dominates the citizens of China, everything is subject to the declared plans of the state.
This is not the case in other countries. In other countries, citizens either have more personal rights and freedoms or are able to circumvent laws and regulations.
Yes, I agree that CBDC has many disadvantages compared to Bitcoin. That is why (in my opinion) Bitcoin will not disappear and will be accepted as the world's reserve currency. CBDC cannot be the world's reserve currency, as it is under the full control of the state.
The financial system needs a standard of money, and this is Bitcoin.
