I wasn't around for the creation of the internet or the "dot com bubble", but I've spoken to enough people that were to know that when the world wide web was first introduced, it wasn't adopted overnight. People were skeptical, indifferent, they laughed at the idea of it… A lot of the same reactions we see towards crypto/blockchain today.
Nowadays, the internet has completely changed the way our society works. Every aspect of our lives depends on the internet in one way or another. Needless to say, the web has come a long way from it's 1990s existence, and it continues to evolve in ways people back then would have never imagined.
The same thing will be true of crypto and blockchain technology. This space is so new and full of untapped potential. The use cases that already exist are just the beginning. 30 years from now crypto and blockchain will have changed our society for the better, just like the internet did.
It's a matter of when, not if.
