newbie often run into losses when investing in new projects. ,i once bought new coins but i can't resell them. i think i have been cheated

what can you suggest to us and how to find out if the project is a scam? Is it true that new Coins can give big profits as people say on youtube channel?
These are the reasons why most newbies have been tricked and got fallen into the wrong investments.
* Lack of knowledge and experience
* Wrong investment plan - they believe Ponzi scheme or quick rich scheme
* lazy to do research - they just follow what the others are saying rather than making their own research to verify them.
Invest first to learn about the crypto market before making a decision to invest. In this way, you can't avoid investing in unreliable and scam projects.
