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.
It is good that there are countries that have accepted Bitcoin as an official currency and made it legal, such as El Salvador, and I see that many countries will spotlight Bitcoin and cryptocurrencies and accept them in the near future. Bitcoin still faces many challenges in the face of governments and central banks of many countries, Bitcoin has wonderful advantages that we almost lost in dollar and fiat money. It facilitated global financial transactions and gave privacy. Some countries were able to use it to finance wars and charities, and it proved efficient in times of crises and epidemics. If Bitcoin is accepted and adopted, the world will undoubtedly do well.
