Very worthy but br careful in what you are choosing to make investments,too many scammers and scam projects out there and we cant even know who theybare so investors make investments only in legit projects like Dencoin tokens.
the keys for the OP is only how he choose the right altcoins to invest, because not altcoins will have a chance to grow buddy
learn about the project deeply is very important before investing, so, you will drop your money to the right altcoins
With the top altcoin on thet top 20 I think just agile in reading news about what's coming out of the project. For example, the LTC is about to havling, making it constantly increase in the past few weeks
