Are they asking because they know there are special skills in altcoin analyses or some people are good at picking g g the right coin to invest in?
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.
We can make research and compare what we produce from the research we do with the opinions of other people. Sometimes we cannot fully trust other people's opinions and we cannot completely trust them, it depends on what project they suggest. If we do our own research we can find out the reasons that make other people suggest or not to invest in the new project. For the decision, it becomes a decision that is absolutely in our hands. But the decision must be in accordance with our research, lest we do it by trying our luck.
Well, we might rely on luck on our first try but it doesn't mean we have to do this the next time. Because I believe that a newbie must adhere and spend more time in the market studying the market behavior in order to gain more ideas. Research should be done and taken seriously but collecting opinions from others could somewhat help us a lot to identify which projects are worth investing and we already have the option so we don't waste our time but rather focus on those suggested projects.
