If the bitcoin bill is passed and becomes El Salvador's legal tender, it will be a great progress in the cryptocurrency and bitcoin industry.
Starting from El Salvador, it gradually influences other countries and finally the whole world. This is an important part of social and human development.
It was only a logical thing to do. A large part of the Salvadorian population is working in other countries and they send billions of USD worth of remittance every year back to their home country. Bitcoin makes these remittance payments more affordable when compared to other services such as Western Union and Moneygram.
