I really agree that bitcoin is better than cash especially today we live modern society and people are almost using technologies. I believe that bitcoin can make the society  into cashless society. THis digital currency is more convenient and it makes the transaction fast. You just need to be careful with the hackers. In fact, based on my situation from now I still need cash because my country is still not accepting bitcoin. So as I earn bitcoin I also turn it into fiat when I need it.
