To go into detail would be quite lengthy; I can provide a brief suggestion, which is also my personal opinion:

In-depth research about the project and the people behind it is crucial. Find out about the project's founders and development team. Do they have experience and reputation in this field? Is there reliable information about them on the internet?

Check the project's social media community. Follow the project's social media pages to see if the community is active and positive. If there are too many fake accounts or bots participating and creating posts or comments, it could be a sign of manipulation.

Examine general information about the project. Review the project's goals, the technology they are developing, how they are raising funds, and the structure of their cryptocurrency. If this information is vague or unclear, it could be a warning sign.

Limit investments in new projects. If you are new to this field, restrict your investments in new or widely unadvertised projects. Instead, focus on projects with a history and reputation.

Use project review and analysis websites. There are many websites dedicated to reviewing and analyzing cryptocurrency projects. Use these sources to learn more about the project before making an investment decision.
