If monetary policy concerns, untested money printing and ever-increasing inflation continue to worry both retail and institutional investors, they will look for alternatives that provide the security that Bitcoin provides in a unique digital format.
Definitely Bitcoin and cryptocurrencies have much more advantages over fiat money and it would be much better to use them. From the point of view of governments and the people who control us, through cryptocurrencies they will lose this opportunity and there is no way to manipulate people with their finances.
Although inflation is an irrefutable feature of legal currency, it does not mean that inflation is necessarily bad. The government can use inflation to macro-control a country's economic conditions. For example, when a country encounters a fiscal deficit crisis, the country can maintain the stability of the country's economy by over-printing legal currency. At the same time, Bitcoin's deflation will also bring many unsolvable problems. When all bitcoins are mined, bitcoins will not have any supplementary means. In this case, people who hold Bitcoin in their hands will hold Bitcoin more firmly, because they know that the price of Bitcoin will rise in the future because of deflation, and they are more inclined not to sell Bitcoin. The number of bitcoins in circulation on the market will become less and less. When the transaction volume is in a state of daily decline, this itself is an unhealthy system.
That is why the function of Bitcoin may slightly change over time. Nothing is set in stone and if there is no emission from the block reward anymore or at least an mission close to zero its primary function may turn into being a store of value, while for a while before we reach that point it might primarily serve as a payment method for large payments cross border.
