Bitcoin isn’t yet a daily necessity, because we’re used to paying with legal tender, but it turns out that the existence of cryptocurrencies also facilitates our day to day transactions. So if there’s no cryptocurrency, there may be other technologies that improve our lives, because technology is advancing, computer technology is advancing.
Yes Bitcoin is not a daily necessity, people can live without bitcoin but because of technology advancement more people engage on crypto currency as a sort of financial earnings and even in the flow of financial transaction on this digital world. Bitcoin is an option and opportunity to make more money and in the coming future I believe that the world can't run without crypto currency.
