I believe the reason why most people prefer to use cash even though its "crashing" is the ease of use. I mean, all businesses accept it.
Though, I am interested when the time comes where crypto would be widely accepted or used the same, or even greater, than fiat. 😊

I have a few silver coins here too. The total is less than 10 pesos during the time of my grandparents (1903) and I wonder how much this cost as of now. I want to sell it but at the same time keep it as it might become rarer in the future. 😊
