when people are not trusted paper money that's why cryptocurrency well developed like higher than we are expecting they says people are unsatisfied with the usage of normal paper currency and the cryptocurrency is not owned by anyone and it will be a good development also for the circulation of people society.
but now the opposite is true. many people lack trust in bitcoin, so prices continue to decline. whereas paper money is still as usual, used for daily use. therefore I think bitcoin as a complement to paper currency transactions is good, considering the fiat currency is difficult to replace by btc
I mostly agree with your point
But as they say, the devil is in paying special attention to detail. For example, there is only one Bitcoin out there (well, if we exclude from consideration all its ugly copycats, of course), but there is no one paper money as there are almost as many fiat currencies as there are countries in the world. So when talking about "paper money is still as usual", you should spell out which paper money or currency you refer to specifically. If you refer to Zimbabwean dollars, for example, this is simply not true
