DYOR (Do Your Own Research), don't fomo into coins just because they are pumping in price. Read through their code (or how many contributors, how much contributions it gets, etc) which is something that you can't do with current financial system and if any of those projects don't open source their code, stay as far away as possible. Inspect the on-chain data to see how much is it actually used, etc. Look at Google Trends, look at their community sizes, etc.

There's a lot of datapoints that you can use or you can find reliable people and rely on their judgments. Also, if you're simply looking for investment, you can't go wrong with BTC/ETH portfolio, they have been proven to work over many years now and most of the remaining altcoins are correlated with them in price anyways.
