The dollar is in a major bubble. The issue is it has the full backing of the US government and military at the moment. So until some country or people have the cahones to step up to the USA (biggest bully on the block), the dollar will continue on.

Support will wain over time and it already has. The movement will start off slow like it is now until it builds up a head of steam, similar to cryptocurrencies in 2017. When the dollar gets to that breaking point, it will collapse. It will probably happen once crypto becomes mainstream and breaks the 10% threshold of people involved. Many people get into crypto to make money, but when they learn about the freedom that crypto and Bitcoin and the blockchain is supposed to provide from governments like the USA, they will slowly awake as well!
