1. the protests have been going on since june.. bit late to the scream party
2. today the government is withdrawing a potential bill that if it were not withdrawn would cause more chaos. thus he has now allayed the reason for the protests.. in short they have no reason to protest
3. a protest is just people turning up and shouting... what exactly would be donated.. mouth wash, shoes? hong kong aint that poor
4. trying to use proper political problems as a gimmick for some bitcoin advertising where one person has to convert fiat into btc for like 1 hour which gets converted to another fiat is not good use case of bitcoin. the fee's alone would actually sway people away from using it
