Foundation matters, Bitcoin has it most-solid, it created the idea, without Bitcoin, no cryptocurrency. Who dares belittle Bitcoin with Ethereum again? Only a fool, 2025 is not 2021. In 2021, also before then, you would hear it loud that Ethereum will beat Bitcoin one day, yes in their dreams. 
Bitcoin broke the 2021 ATH [$69k] in 03/2024 to reached $73,850, recorded a new height in 11/2024 [$108k], finally the current ATH≈$110k.
What did Ethereum? Nothing, it has been lazy.
The ATH of 2021 [$4,870] is still holding in 2025.

The ATH of 2021 [$4,870] is still holding in 2025. That's why in this bull run cycle, we have said that it could be the first time that we have seen Bitcoin and altcoin market decoupling because of what you describe. There's no altcoin season yet and when you visited their board, everyone is asking about when it's going to happen. But the money is still in the Bitcoin market, and even if we see Bitcoin going down, investors sold and hedge their money on stable coins and not on altcoins.
But we shouldn't rubbed it in to the altcoin investors here, LOL, they could still be thinking that they would still have their own version of the bull run. But it's really hard to see how it will go on their way when Bitcoin is having a good run and it's expecting that we might touch based prices around $150,00-$180,000.
