No, any problem with Ethereum (ETH native) means a problem with all ERC-20 tokens and vice versa.
the increase in Ethereum fees means that all other networks will increase in value, which is what happened to BSC.
Ethereum and ethereum tokens are altcoins. Why did you not just mention the name of the altcoins and tokens directly, no need to mention altcoins again because ethereum and ethereum tokens are altcoins. You can have your portfolio the way you want it but because this is public, it has to be different. You can begin like this
1. Bitcoin 70%
2. Ethereum 10%
3. BNB 10%
3. Ethereum tokens and BNB tokens 5%
4. NFT 5%
No need for altcoins to be included again is what I am saying.
