Both of coins is best coin.
Nah. Only one is the best coin, and it is Bitcoin.It covered the all markets. Nowadays Ethereum is trying to reach the bitcoin prices place. But anyone coins is never willing be reach the bitcoin place. So bitcoin is king of all coins. Bitcoin is best one the all coins. No one can reach the bitcoin place. It never will be get down. That's the reason people will be trusting the bitcoin.
People trusted Bitcoin because it's the only true decentralized crypto, it consensus, and it's ability to connect people from different background despite their ethnic/religion believe.
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.I agree that Bitcoin is the founder of all cryptocurrencies because it laid the groundwork for them all. Regardless of how promising an altcoin is, it will never be as good as Bitcoin. Furthermore, they are merely an alternative if we judge them by their name, altcoin.
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.
Ethereum was not the next of kin of Bitcoin; the Bitcoin next of kin was actually Litecoin, but it lost the community's trust when Charlie Lee made a public announcement about selling all his LTC bags, which the community saw as his exit plan scam.
