I enjoyed your post. If I look around some of the friends I have introduced into crypto I can see, almost none of them get into group three. Some have started joining one or two services for a while. Many have started joining Hive and given up. Others are trying to "catch" the easy money which is a quite poor way to enter crypto although at least some may get hooked if they are lucky enough to get some nice easy airdroped rewards.
Many years ago, when I was still in college, I started reading investment books. There was one that impacted me with just the first page, the author stated most of us spend years in educational institutions to learn how to earn money, we get a job and start earning, but spend very little time learning how to manage our money when there is clear evidence you can make more money managing your assets than working to earn them.
I believe crypto gives every one of us a way to try to act as those in group three, especially if we are in the position of living with our "regular" jobs and keeping crypto earnings as a future asset providing us more instead of withdrawing benefits.
