What coin can you add to bitcoin and ethereum to make a BIG-3 cryptocurrency?

Bitcoin isn't the only cryptocurrency available but Bitcoin still continues to lead the pack of cryptocurrencies in terms of market capitalization, user base, and popularity. Which makes him the KING of cryptocurrency worldwide.

Other virtual currencies such as Ethereum are helping to create decentralized financial (DeFi) systems. Ethereum(ETH), is a decentralized software platform that enables smart contracts and decentralized applications (dApps) to be built and run without any downtime, fraud, control, or interference from a third party. The goal behind Ethereum is to create a decentralized suite of financial products that anyone in the world can freely access, regardless of nationality, ethnicity, or faith.

Ether, launched in 2015, is currently the second-largest digital currency by market capitalization after Bitcoin. That makes it second biggest cryptocurrency in the world.

On Sep. 15, 2022, Ethereum completed its long-anticipated transition to the proof-of-stake (PoS) validation method. PoS is less energy intensive because it removes incentivized mining, makes the blockchain more efficient, and allows it to scale better. Making it to always be the best altcoins and left it competitors behind.

But still yet, most if this coins doesn't seems to feel recognized as bitcoin and ethereum are.
