What are the possibilities of Bitcoin becoming the central world currency.
For now I have not found a bitcoin expert who speculates that Bitcoin will be the world's currency, try to think logically, bitcoin can be touched, bitcoin can be exchanged physically like fiat money, obviously not.
And I have not found a single expert (in the cryptoindustry) whose forecasts would be accurate.

All their assumptions look like a game of roulette (guess right - guess wrong).
Although I am far from being called an expert, I agree with the opinion that bitcoin will not be allowed to become a world currency. Otherwise, why would big countries prepare to issue their CBDCs? Instead of bitcoin, powerful countries will make some CBDC or issue (in cooperation with several influential countries) an alternative CBDC specially created as a world currency.
You need to understand, there is no one country or government that recognizes digital currencies that are made into the world currency, Bitcoin is still operating with a decentralized computer network system, blockchain, who guarantees that the network does not Lost, one hour of lost internet network you can't do anything with Bitcoin, how such things can be used as world currency, whether it is logic and as it is common sense.
I believe that decentralization will be one of the reasons why bitcoin will not be recognized as a world currency. For one simple reason: the impossibility of controlling this currency. And why make, consider, the strongest currency the asset that you can't control (manage)? Therefore, bitcoin as a world currency is a utopia.
