I am sure that you mean the tokens that use the Ethereum platform or ERC20 tokens. For me, the Ethereum coin is not shitcoin. But some ERC20 tokens in the Ethereum platform are shitcoins (so do some of the BSC tokens).
We also notice how popular NFTs and new types of coins are right now. Many people are increasingly coming to the crypto world because of the hype tokens happening these days. And this will be never-ending because there will be always something hype and attracting many people.
But, popularity will not defeat the trust and value of Bitcoin. I personally don't believe Ethereum moreover the ERC tokens will even surpass Bitcoin
I think what OP wants to say here is the ecosystem, we all know Bitcoin and Ethereum ecosystems are purely different and created for different purposes.
This kind of comparison is useless for me, it just doesn't make sense, if you really know how Bitcoin and Ethereum works, you will know.
