I think that bitcoin was created to kill the dollar, even though it could take 100 to 200 years to play out.
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.
Not only during the war in Russia and Ukraine, people were helped far and wide by Bitcoin, but also when the global corona virus took the form of a pandemic, many donations were made through Bitcoin. Even when Turkey's highest magnitude earthquake hit the city of Turkey and many people died under the rubble, a large number of people donated through Bitcoin. Bitcoin is a reliable digital currency, which can be used in all fields. The popularity of bitcoins is gradually increasing and the popularity of the dollar is gradually decreasing. Just as El Salvador has approved Bitcoin as a legal tender by keeping their country's currency, many developing countries around the world are making plans around Bitcoin. For a long time, the dollar has been used as the international currency worldwide, so it will take a long time for bitcoin to take the place of the dollar, but at some point, bitcoin will definitely be more popular than the dollar.
