El Salvador is a country that has adopted bitcoin across its entire economy, not only investing in it but making it a legal tender. But after 4 years, let's see how their economy is. Their economy is on the brink of default and has to seek help from the IMF.

It can be seen that bitcoin cannot help or change the economy of any country, let alone the global economy. Bitcoin is just a currency, an investment asset, and it may be useful for an individual or company's economy, but it does not help the national or world economy. The national and global economy is much more complex and requires many more factors to change, we cannot rely on bitcoin or any single tool alone to change.
