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 remember this scenario from the Cyprus crisis.
People were saying greeks are buying bitcoin because the banks have frozen their accounts, but I still haven't figured out how you can buy coins with your money from a frozen bank account

I hope it just end in war of words which is normal between two nations.
There are no two nations, HK is an autonomous region with more than 90% of the population being Chinese.
War is never the solution as it takes economy back for both the counties and also the world economy falls due to such tensions.
Oh, this one is new, both are counties now, in which state? Texas?
