In 2019, I was fascinated by Bitcoin after I was introduced to it. I have been following the attitude of governments towards bitcoin and hope it will be promoted. However there has been too much negative news in the past two years. I reacquaint myself with bitcoin and fiat money.
Money is a tool for exchanging goods and services in human social life, and whichever tool makes it into the system becomes the de facto currency. Governments regulate the economy by issuing money, which means they can control it. Bitcoin, on the other hand, cannot be controlled, which is why we like it, but also why governments don't like it.
After I figured it out, I no longer expect Bitcoin to be recognized by the state, and it doesn't need to be. It is part of a special asset, not a currency.
So I don't think Bitcoin is going to become a fiat currency.
The goal of Bitcoin is not to become the world currency, and no one wants it to be the world currency. As a currency, it will coexist with other currencies and cannot replace other currencies.
Bitcoin is not so much a currency as it is a tool for investors. Investing in Bitcoin can avoid inflation, and long-term holding can also make profits.
