I remember when the war broke out between Ukraine vs Russia, at that time Ukraine received many helplines via Bitcoin which were sent by many people in the world. Bitcoin has better advantages than Fiat. Yes Bitcoin will slowly kill the Dollar. If you say 200 years in the future that makes sense because Bitcoin takes a lot of time to collapse the dollar. Mass adoption also continues to see a good rise in the development of Bitcoin as many companies have seen Bitcoin as a healthy currency for them to have in their treasuries.

Developing countries will continue to follow the development of Bitcoin from time to time and it is very likely that the entire world community will make Bitcoin their target investment vehicle and fiat inflation will make Bitcoin one of people's goals for owning it.
