no because nothing about "people" would ever change. they would only use a different tool (bitcoin in this case) and continue doing the same thing that they have been doing before and nothing will ever be solved. not to mention that bitcoin is too small and not even adopted yet by more than 0.5% of the world to want to change economy of country!
I guess you are right. Even if crypto becomes popular and used by everyone in the world, it still depends on the people and what they do with it. Its a shame because crypto can be used for a lot of things and perhaps can even help the economy... of the third world countries to be exact.
