$ETH Ethereum is a fascinating project—it's not just a cryptocurrency, it's a whole platform for decentralized applications (dApps) and smart contracts. That’s what makes it stand out from Bitcoin.

I think its shift to Proof of Stake with Ethereum 2.0 was a huge step for sustainability and scalability. Still, there are challenges: high gas fees (though they're better now), competition from other blockchains like Solana or Avalanche, and regulatory scrutiny.
