Maybe in 10 years from now, my beliefs are the roles will invert, transparency that comes along with cryptocurrency will not allow outlaws to do business and they will use fiat currency so 80% of peoplewill use digital money (AKA current cryptocurrencies) and the remainder will user paper money due to different reasons
This is probably going to take many years to come. Because the dollar represents the United States' finances, if bitcoin replaces the US dollar, it shows that the US government has accepted bitcoin as a replacement for its dollar, which is quite difficult. towels are acceptable. I think the best option is that bitcoin and USD hold the same value for the rest of the currency.
