I doubt that it will die, just look at the fundamentals and how it is working since its inception. Yes, there are problems, yes we need much much more development, but at one point everything will be solved. People thought that no one would want to have a computer at home because it was too slow, big, didn't had many features, the internet followed the same path, the crypto will follow it too, but guess where the last two big invention ended - in your pocket for everyday use, I think that the last invention will end up there too.

Completely agree on that, crypto was born for more than one reason and it fixes the main problems that are present now. Of course we should expect in the future new problems to arise but they should be solved faster than ever.
