Every beginner needs to know that 99% of altcoins will go to zero. Perhaps a few of the altcoins we have right now will survive the long run. History has proven that altcoins usually do not have anything to offer and are mostly speculative instruments in the cryptocurrency world.
Bitcoin is the King. Remember this when the next forked coin claims it will do the flippening and replace Bitcoin in dominance. Don't make the mistake to listen to sock puppets and influencers.
Maybe many of them failed, but there are still some altcoins that were built with a good reputation. I can't blame you with having a mindset that most of them are not worth the money because we're at a time where scams are so prevalent and beginners are most likely to fall for it because they take a risk without doing advance research about the potential risk and dangers they may face. This is the reason why research has a significant role in everyone, it presents a different view of things. That way, you will have a sufficient understanding of which coins are a good investment.
