Before venturing into any investment, you should always conduct an extensive research to lessen the risk of getting scammed or losing your money. Carefully analyze the project's mission and vision. Check out its white paper, roadmap, and affiliations. They must have a dedicated, legit, and transparent team. A positive community that supports the project is very important as well. I have taken into account the above criteria, that's why I feel secured holding some top-performing cryptocurrencies in my portfolio including this undervalued gem called Stakenet XSN.
