Can Ethereum fail eventually?

I’ve been in the crypto space for about two years and I mostly spent my time reading about LUNA (I lost $16k which was 70% of my savings). It could be true that LUNA is the only ponzy scheme but I lost trust in pretty much the entire market after that crash except for BTC and ETH. I’m still a little nervous about everything though.

I’m okay with looking stupid so I will ask: Why would ETH continue to be valued more than other altcoins? Is it the security of having too many validators? Can’t projects like Elrond Network or NEAR Protocol surprass Ethereum while it takes 6 years for ETH 2.0 to be fully deployed?
