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. 
Yeah... Bitcoin is really the father. In every environment there is always a boss or morover there is a difference between father and son. As of now Bitcoin is the father of all and any other Altcoin remains it's subject and may not be as Bitcoin. There is a reason why Bitcoin is the boss. First it was the first coin that was created by Satoshi nakamoto, and it is limited in supply and recognize and trusted by many. People buys Bitcoin more than any other Altcoin. Ethereum is the next of kin to Bitcoin so Ethereum can never inherit the property of Bitcoin while Bitcoin is still alive lolz.. that is the only way I can describe it to you right now.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.
