Why are you caring about those people? Every person want to try himself in this kind of job. Of course, no everyone has gained success in it, but at least they tried. Today it is modern and interest so a lot of people want to be a part of it at least for a while.
I also think that there is no need to think about these people. The main thing that comes to me in cryptocurrency is that it allows everyone to realize their capabilities, you can not be stupid and make good money in crypto, you have to develop and get better.
