So the question is, how do you think, should Bitcoin replace Fiat money, or there are other options of how it could be useful to the society?
Edit: To give you more food for thought, there is a nice article about the history of the creation of both Fiat and Bitcoin and their detailed comparison.
Fiat still far ahead of bitcoin in many ways. Its crystal clear that bitcoin is still behind. If you say many country are in huge debt today, i won't disagree over that but they are in debt not because of fiat but a bad governance like the case of Venezuela. If Venezuela adopted bitcoin today, it won't take them out of recession or make them rich.
