In this history of mankind any kind of innovation to solve something has always benefited it does however takes its own time to fix things .. look at those trillion dollars of debt in u.s if they don't pay the entire country goes into bankruptcy and this not only affects one country but several others will be down along with it .. we need robust technology to solve such things if humans keep using paper money it will not only cause problems to the country but to its own people. adoption of block chain is very important in near future. lets see how much we care .. if Government really needs to solve their debt issues blockchain is the only way out to convert their useless fiat to valuable blockchain technology it will not only help to crush fiat and pay of trillions it will help to rescue the majority of countries in Asia and worldwide.
In my opinion, there is an advantage and disadvantage of bitcoin in replacing the fiat money. Advantages is that it will be supported by many investors and many of us will be grateful when bitcoin replace fiat but the disadvantages are it can be used by the government and the worst is it may become centralized.
