How come your example can be applied to banking industry.
Banking industry is so vast that even if crypto will be the new thing , still they will remained. But prior to that, it will be very difficult to erase banking system even for decades. Honestly most crypto users here have a definition what is bank just because of interest vs holding cryptos. It's not like that.
Banks are not designed just for saving the money scheme. It has many purposes and advantages. Im a crypto enthusiast but not to the point that I will erase what are facts and closest thing to happened.
Banks "die" every year over the world. Of course, they don't die off, they are being bought by other banks, their products are changed and re-branded and so on. I don't know why this is hard to understand.
Of course,
the whole banking system will most probably don't die off. Despite of many bitcoiners' opinion, I too believe the banks are useful. And most of them can evolve.
