You don't buy coins blindly because it is cheap so you don't get trap. Many projects are dead on arrival and so when you invest, you go down with it . You need proper research before investing on any project.
Rookie mistakes some investors still make. They believe that because the price of a coin is low then there is the opportunity to hide it to the MOON when there is a Bull market, they forget that some projects will not make it to the next Bull market and even the ones that do, some will never get beyond a certain price.
I remember a project I invested in back in 2019 and the price now is 10x less in the Bull market than what it was when I invested though I have since cut my loss.
