Bitcoin is a currency whether you accept it or not and it was never supposed to become the "world currency" it is supposed to be a global currency which it is.
Governments regulate the economy by issuing money,
Wrong. Governments regular the economy by setting rules and enforcing them not by printing money.
Bitcoin, on the other hand, cannot be controlled, which is why we like it, but also why governments don't like it.
It depends on the country and the government. This is not a global issue.
The key to whether Bitcoin can become a world currency does not lie in Bitcoin itself. Bitcoin relies on the underlying technology of the blockchain to operate automatically, and its characteristics of safety, reliability and decentralization are indeed unquestionable. But Bitcoin cannot be separated from society and politics. If more than 80% of the countries in the world ban Bitcoin in the future because of the increasing threat of Bitcoin to legal tender, then it will not become a world currency. This is the key factor. Now people use Bitcoin as an investment channel and tool, and the government also considers it in this way.
