No assurance for it. But only depend on your skills in trading or how much you invest in the right project. It takes a lot of research by yourself too, you can't just trust the research of someone else for they could just be shilling. As a matter of fact, the projects included in the honorable mention are a lot more promising than the top 10 you listed such as the SAND and Elrond. You can only become a millionaire also if you also invest a big amount.
