Crypto is here to stay.
In the future maybe become as alternative for cash.

It was expected to become an alternative to fiat money - that is really what it meant to be. However, the adoption isn't as fast as we think, it is very slow due to people aren't ready yet.

Let us say that major cities and countries have used this already but for sure many people continue to hold and use cash themselves.
