The world dependence on the dollar is certainly the biggest advantage of the dollar owner, the value will continue to rise so as to make many countries try to leave the dollar and look for other alternative payment systems, the presence of cryptocurrencies should be a solution for the world to be able to solve financial problems.
The problem is that it will not be easy for every country to implement cryptocurrencies into their payment and financial systems because every country also has rules that must be looked at before agreeing on any new thing to be implemented. So this is not an easy matter for all countries even though it is an option with the aim of making it easier for all countries not to depend on dollars which are in fact still accepted and still useful in almost all countries in the world.
