Although currently many countries have banned bitcoin but I'm sure they will soon follow countries that have legalized bitcoin like El Salvador, it's time for countries to think about making their people prosperous and bitcoin is a great opportunity to improve everyone's welfare.
Yes, you are right, in fact El Salvador has a huge advantage over other countries, and that is that they live on remittances, and yes, if the BTC is legalized in much of Latin America, it would not only bring more demand and trading volume to btc and it would make it rise even more in price, but it would also begin to generate by the governments taking their good piece of cake due to taxes, it would be a total empire for both the government and the banks, because the banks would quickly obtain greater liquidity, and a good loan offered by a bank to a person in BTC whose BTC price continues to grow will be more money for the bank, of course the opposite process can happen but this would only be a possible scenario and could result in more debt , at least for those of particular economies.
