You have to be careful, my friend. People will always tell you their wins but never tell you their losses. So, the first thing you should do when someone tells you a certain gem will do 10x, 20x, 100x or more, go out and do your own research on the coin.
What you should probably be looking out for is the team behind the gem. Are they doxxed? What experience do they have in the crypto space? What they're building, is it feasible? Is it marketable? Does it solve a particular need for a large section of people?
These are some of the questions you'll want to ask yourself before apeing into just any token.
I agree with that. In the crypto space, especially in social media, people will barely share their losses or discuss them, but you will always see them posting screenshots of their wins and profits, pretending to be experts in the market, and such people will also be seen providing suggestions and recommendations to new investors while they are in loss themselves. So, these kinds of suggestions from such people should never be taken seriously and one should do their research if they find a project to be interesting.
A lot of new investors make the mistake of investing their hard-earned money in gems that are suggested by someone who has no idea about the market at all. And newbies, just because they've seen some gems gaining value, think that it is the ultimate shortcut to richness and they can earn a lot of money by investing in them.
