The only scenario where this can affect BTC prices is if HK residents have their bank accounts somehow intervened by China and they can't get their money out, or if the HKD ends up hyperinflating as is the case of Venezuela and to a lesser extent Argentina.
I don't even think that will affect Bitcoin's price. It's easy to link whatever problem in the world to an increase in Bitcoin's price, but it's impossible to actually prove that the problem you think helped Bitcoin increase actually is responsible for that.
I remember reading about how back in 2013 Bitcoin's pump to over $200 was caused by the problems in Cyprus, while that most likely wasn't the case at all. Most average people there probably didn't even know what Bitcoin was.
The thing with crypto related news outlets is that they always try to make it seem like people in whatever shaky country are using Bitcoin or crypto, but most of them obviously aren't. They have other problems on their mind.
