if we say, bitcoin is the currency of the future, we can say yes, because we can see bitcoin continues to grow, and many of us have adopted bitcoin, even large companies have accepted bitcoin, and there are governments that have legalized bitcoin, but we need to realize bitcoin cannot replace central money, fiat currency..
No matter how effective bitcoin is for dealing with financial problems, it will not completely replace fiat. firstly bitcoin cannot be fully controlled by the government, secondly the uneven development in all corners of the world makes many limitations related to the operation of cryptocurrencies which are highly dependent on technology. the government might make adjustments to digital money, which is more user-friendly and easier to monitor.
