2) have you heard of lightning network or strike? So far the fees have tended to be quite low on lightning network (and strike too, from what I understand - nearly free), but surely if the the quantity of usage exists longer in El Salvador and become more widely spread in terms of people transacting in bitcoin in El Salvador, probably the fees on lightning/strike will adjust to those new circumstances.. competition will likely come in to El Salvador, too.. in terms of other ways to use lightning network or maybe other second layer or even first layer transactions.
So far offchain networks like LN have been an epic fail for adoption,
the reason being it is far cheaper to use an exchange that does offchain transactions between their users at zero costs without the tech headaches of the never ending beta code.
From what I understand El Salvador, is trying to get a 1.3 billion dollar loan from IMF.
Most likely, their leader is trying to use bitcoin as legal tender as leverage to make sure they get the loan,
and as a condition of getting the loan , expect a ban on bitcoin from normal commerce to follow shortly after.
He cares little for bitcoin , it is nothing more than short term leverage to get the 1.3 billion dollar loan he wants.
Politicians work like that.
