That comes off as quite a novel theory to me to be suggesting that a government has not implemented something properly based on the fact that there are protests. Another question is about how much you seem to be presuming that the protests are representative that the "people" are against the way the law was implemented in El Salvador..
JayJuanGee, sorry I'm late in answering this question. I have no reason to say that I have a lot of knowledge about the real condition happening in El Salvador regarding the legalization of bitcoin as a legal currency. I read some news about public protest there which may not be pure without political engagement between the government and the opposition. I can assume that this protest was carried out not only by the wishes of those who disagree with the legality of bitcoin, but that the current political opponent of the government may be able to form an opposition to this protest in the name of society.
Regarding how taxes might be imposed upon the people, each country comes to its various balances in how they collect taxes to fund various aspects of governmental expenses... Do you have some specific examples of any recent government announcements regarding the various ways that you are speculating that the El Salvador government is going to tax bitcoin related transactions? By the way, this thread is not about other crypto currencies, so I cannot see how it might be relevant to say that the El Salvador government is going to do x, y or z in relation to bitcoin merely if they were to announce some taxation policy in regards to some other cryptocurrency? You might have to explain if there is some connection that you know about that is happening in El Salvador or you are speculating completely without any information at all besides some kind of a snip-it that you heard in Mainstream media.. which also might not necessarily be representative of what is actually going on (on the ground) in El Salvador.
The main purpose of adopting bitcoin as a legal currency in El Salvador is to reduce dependence on using other currencies such as USD for transaction between countries. There is a big benefit that government expect from this adoption which is that they can save a lot of transaction fees each year from citizen working in other countries like America.
Regarding taxes, I haven't gotten much information about it. But maybe it will be proposed soon considering it can help the country to increase its income, but this is just an assumption that may not be justified or wild speculation from me.
