Thank you for your comment. No, we not sure! Nobody can be sure that a project will succeed or not! Whatever we all search, we can't predict and be sure!
Here BestCoinList attempts to submit projects which seem to be successful but also never can sure about this! So, you can choose one from those projects that you think are worthful. We also provide a rating system that can help you to choose.
But we all should never forget that cryptocurrency is a risky industry always.
