There is a real demand for crypto currency in the real world? How many areas of cryptography have rooted in everyday life and in the thinking of every "citizen of the world"?

This question can not be answered clearly, because it is not known exactly how many people know about crypto-world currencies. It is not known exactly how many people will learn about it day by day, but the fact that they will find out for sure. Therefore, in a short period of time, the planet's population is fully aware of the latest technology that develops in the field of more intensive cryptographic audits. Is that bad? I can answer firmly that it is not innovation, it is an improvement of the world, the improvement of life, the comfort it is, it is something new, and something better than that.
