There is a wrong assumption being made by the OP. He feels that it is the young people who make mistakes for most part in the cryptocurrency sector. However, I have to say that the reality is very different. Look at various Ponzi schemes which involved cryptocurrency, such as OneCoin and PlusToken. Most of those who lost their money were middle-aged or elderly. I would say that OP should remove the "young" word from the title. Inexperienced users are more likely to make mistakes, and it doesn't matter whether they are young or old.
I believe that it is not that young make mistakes, but young make mistakes based on high risk and high return. That is sort of true, of course there are older generation that do make mistakes like that, but the older you grow the wiser you get that nothing in life is that easy and you can't just put 100 bucks into something and make a profit from that. Which is why we are looking for things that can make us richer in years, or even over a decade whereas young still do not realize that and all their tech startup dreams and crypto richness and many other stuff like that and this is why we have to realize that young go into high risk high reward a lot more than anyone else.
