I'd say its too late. But, as an alternative for storing money, it is great. Do not expect to get rich from it tho, its simply your savings in a better place than a bank (as long as you have the discipline to handle money correctly, ie. cold wallet no insecure OSes).

Millennials are those born after the year 2000 iirc. And i read somewhere those born after 2010 are alpha, still don't know the term for those born after 2020. There is a bunch of names for the previous decades.

Its so funny there are even shows trying to show youngsters how life used to be before smartphones and internet. If you watch old shows, there are some things you will have to ask or search about, and there are several youtubers dedicated to this as well.

When i started using Internet in the 90ies, there was no Google. Think about it. Yahoo was the preferred go to place, and that thing was maintained manually (if you made a site, you had to submit it for them to add it). You needed to go elsewhere for better search results, i remember using webcrawler before google appeared but there were a couple more machine fed search sites.
