I just looked at that data on CMC, and it says that there are currently as many as 13 281 cryptos, and that just shows that everyone wants to have their own coin/token and profit from something that has been a very hot thing in recent years.
They're seriously pumping or it just seems to you? It’s easy to fool any beginner and one who isn’t aware of how a market cap works, but even such manipulative methods aren’t enough to do what you think. Bitcoin max supply is just 21 million, and its first companion currently has 118+ million in circulation and that number is increasing - and now imagine that each altcoin has a max supply of only 20 million or so - all that pumping you see would seem much less impressive.
In short, Bitcoin has what other coins do not have - real decentralization, properly set max supply and investor confidence that lasts for more than 10 years. You're actually looking for some new Bitcoin, but I have to disappoint you, I don't think you'll find it.
