If it is passed successfully, then if i am not mistaken they will become the third country to make Bitcoin a legal tender, El Salvador can be said to be the country that kicked the ball rolling for multiple Bitcoin adoptions from different other countries, it is just a few as of now in 2022, but in the future when many countries will adopt bitcoin too, El Salvador would be remembered as the first, so no matter how people try to say it is a failed move, one thing is certain and it is that El Salvador have cemented their place in bitcoin's history forever.
