they can only make the purchase process more difficult or illegal.
You're right that they can only make the purchasing process difficult and they've also succeeded in doing so in my country but no matter how hard they try, it wouldn't be a success because I know Bitcoin is here to stay.
If the number of independent merchants is big, then the negative measures or banning of Bitcoin would be a highly unpopular decision by politicians.
That's true because this is really work especially in developing countries where the right of their citizens are valued and respected and in a country like mine where the leaders don't even have any respect for human rights and opinions and they don't even respect court orders.
Even if the Marchants are upto millions, the government of my country cab just suddenly wake up one morning and decide to stop or ban Bitcoin forgetting that they're rendering alot of physical Marchants jobless..
I really look forward to the day Bitcoin vets accepted in my country.
I don't think BTC in El Salvador failed. If it worked in Nigeria, it will work in smaller countries like El Salvador.
Did Bitcoin work in Nigeria?
I don't think so because every Bitcoin related activities are done in disguise and I don't think people openly use Bitcoin and I don't also think Bitcoin will get accepted if banks fail because we've seen alot of banks fail in my country and even recently, there was high scarcity of cash which was one of banks major failure but I never saw people turning into adopting crypto (Bitcoin) but one still has to convert it to Fiat before using except you want to face the charges which isn't small when converted to my local currency.
