Did China do something that made the Chinese people start buying? Or what?

I don't think so, but the applications of the new spot BTC ETF in the United States by giant investment companies to the SEC, such as BlackRock, which is a leading investment company around the world in asset management and has trillions of dollars in assets, this famous name in the world is seen by the community as a positive step for mainstream acceptance to the world of cryptocurrencies, BlackRock paved the way for other companies such as Fidelity Investments and Citadel Securities and others, and their entry into the crypto space led to the price of bitcoin jumping to above $30,000, reaching this price for the second time two months later, after the bankruptcy of FTX and after the regulatory war by the Securities and Exchange Commission on the leading exchnage platforms and after a lot of other negative news that took the price of Bitcoin previously to a low price range, the Securities and Exchange Commission and the US government can fight crypto and do everything they can, but they will not be able to stop Bitcoin.
