The essence of this matter is still because Bitcoin is pegged to the US Dollar.
Indeed, the existence of Bitcoin challenges the role of the US Dollar in the global financial system, even capable of shaking its core.
However, due to the nature of the US Dollar, it is currently necessary to use US Dollar transactions. No matter what currency it is, it ultimately needs to be converted to US Dollar valuation.
To some extent, this has also increased the core strength of the US Dollar in the short term.
This is the reason the United States has not officially banned Bitcoin. They want to participate themselves.
However... Bitcoin in the entire financial system is ultimately a very small link, not considered the focus of financial games. They haven't gone all-in, nor will they pay a significant price to kill this thing.
