Perhaps you are right. Some people/investors are good at picking and market analysis, and some of them are spending more time in the market and checking new projects' progress. And asking for their opinion is a big help for newbies to decide what to invest in and lighten up. Like if you are a newbie, not actually necessary but I think it was more advisable to do this just to avoid investing in a wrong /scam project. But yes, we also have to do our own research, not just rely on their opinion.
