I think the opposite, it won't make a significant difference to the price of bitcoin since Hong Kong is a small country, so it won't have a huge impact on the market. If it's China or some other power, then that's really big news and will have a positive impact on bitcoin. But you are right, this shows that the world is gradually accepting bitcoin and becoming more crypto-friendly. At the current rate of development, I believe that the countries banning bitcoin will soon lift the ban, and the whole world will soon accept bitcoin.
If you consider HongKong is a small country and can not create big effects, you are wrong. Is El Salvador a big country in your opinion?
Effects from El Salvador Bitcoin Legal Tender, Bitcoin Beach City and many activities in that country contributed lot of effects on Bitcoin bull run in 2020 and 2021. Hongkong is a nation that has very close connection with Mainland China and please don't think that China must repeat the same things Hongkong do to see big effects in cryptocurrency market.
Only if people speculate about what China do after Hongkong is enough to create hype and pumps. Because they are very closely in geographical locations, many cryptocurrency companies will move from China to Hongkong to enjoy more friendly regulations there.
