I think what they wanted against bitcoin is the 'capital flight', because we all know that with bitcoin and crypto, you can simply hedge your wealth to it, put in your hardware wallet and exchange outside of the country.
That's why they really attack bitcoin and make a hard line stance, threatening to ban bitcoin mining, ban ICO's imposed fees on bitcoin exchanges in 2017. But even after that although it has created a big impact on the price back then. But right now a news coming from China doesn't have 'jolt' anymore.
If they want to stop the capital flight, then they need to stop manipulating their stock market and the national currency. Forcing the citizens to make investments in overpriced assets is not going to work. Thousands of Chinese investors are renouncing their passports and migrating to Western nations every year. Their stupid anti-Bitcoin policies will worsen this situation even further.
