Finances on their own mean almost nothing. The basis of the development of any state is its economy. Material goods should be created in the country, all branches of the economy should develop, and gross domestic income should grow. And any currency only serves this process. Therefore, little depends on bitcoin in El Salvador. Without a proper organization of the growth of economic development, no currency will save El Salvador. Everything needs to be dealt with as a whole. Bitcoin can eliminate the shortcomings of the previous currency, although it is also not perfect. But it cannot replace the country's economic development.
agree with what you said considering that in this case bitcoin also cannot guarantee their finances from anything because as you said, there must be other good management whether it is infrastructure or other economic strengthening that makes them rich.
On the other hand, bitcoin adoption is actually a pretty good thing, but it is still a double-edged sword that can only make a country worse, especially if it can't manage it properly.
