Douyin has implemented a ban on content promoting blockchain and digital asset market activities as part of its new "Douyin Community Financial Industry Convention (Trial)." The platform's rules specifically target the use of digital asset market concepts to facilitate illegal virtual currency trading and exchange services. Additionally, Douyin is cracking down on stock recommendations that are presented as science communication, including price forecasts and investment tips. This regulatory move could impact the sentiment among retail investors, potentially affecting the fear and greed index.
