All i can suggest is for you to intensify you research before investing on them, i wouldn't discourage you from investing on any since you have already taken the right and appropriate step towards investing on bitcoin and other top altcoins we have, investing on other low cap cryptocurrencies should be on something that you can afford to loose, and if you're that lucky that the projects becomes successful, then you're going to make more money to your portfolio, but never forget that you're taking high risk on them now.
