I also recommended it to my college friends many years ago, saying that it would really be one of those things that people look for and treat as a profitable investment. But maybe many things are still too vague for many people. When they are not ready to get close to them, some newcomers show up at the bearish phase and they say it's not good Smiley . However, in one aspect that has been through so many different cycles, I don't want to share more because it's clear that if you can't see the good in them and they give an immediate investment, then it's hard to be attractive to new people.
