The major problem with the El Salvador Bitcoin adoption presently is the lack of motivation on the side of the citizens and the lack support for the government to help push the Bitcoin project in that country forward.
i can tell you of a truth right away that El-Savador isn't quite about it bitcoin adoption, there have been development of many kinds in bringing this into a successful end, though it may seems we hear less frequent about them often but things were in progress over there, the government does not only focus on bitcoin alone but rather carry other aspect along with how the use of bitcoin could do something worth it in there.
Many of the citizens do not want to sacrifice efforts to help in improving the economic situation of the country,
that's not true, many of the people uses dollar and yet have the alternative one as well which is bitcoin with people in their big numbers making bitcoin payment, transactions while accepting it in their businesses, so here the effort needed from the people is the support in using bitcoin which they are doing already.
