The only good thing here in El Salvador is that this is a living testimony about Bitcoin, because at first they did not think well of it; they were very negative about it before. El Salvador even declared a ban on Bitcoin, but they eventually reversed it.
Then, later, El Salvador declared again but not to ban Bitcoin, instead a declaration that they made Bitcoin legal tender in their country, and most of them are Bitcoin enthusiasts, and it seems that only a few are not yet aware of cryptocurrency.
This full acceptance of bitcoin by el Salvador is a proof indeed that bitcoin can actually be used as a legal tender and although it may have it's up and down but there is no currency in world today that hasn't got his flaws but atleast this is big step forward towards the full adoption of bitcoin in the world. Most other countries worldwide actually protest against the use of bitcoin in their countries because of its decentralised nature but the whole purpose of bitcoin was to give financial freedom which is what most government doesn't want for their citizens.
