Your words have a lot of logic, I think so myself. The way we understand crypto and have a fairly good idea about its future and think that it is possible to make a good amount of money through it. But it is very difficult for us to explain it to the people of the previous day. That's why when we need to invest in a project, we have a lot of trouble understanding them
Keep in mind most of us are relatively young. We can bear a completely different risk exposure. Not saying our parents should go all in, but many of them are used to traditional investment opportunities that are way more conservative than crypto could ever be. Additionally, they are tangible in most cases. We all love the digital world because we grew up with it.
