I guess the main reason why people in country with huge inflation are buying bitcoins is simple, they are trying to save their earnings from inflation.
thats true but there are also people that living on those country that buys crypto not because they they want to save thier money but because they want to experience the benefits of using a crypto .
but that is working while the rest of the world is in a good shape, but if all financial system is going to collapse I doubt bitcoin could be safe harbour for all of us
not really . rest of the world are also experiencing other problems if not about inflation . btc can also get affected if ever monetary system and other payment system falls down because there will be no medium to use when purchasing btc so do you think btc value can grow without them ?
