$ETH Ethereum ($ETH) has been gaining strong momentum lately, especially with the growing adoption of its Layer 2 networks like Arbitrum and Optimism. ETH's transition to proof-of-stake has significantly reduced energy consumption, making it more environmentally friendly than many other cryptocurrencies. As of now, ETH remains the backbone of the DeFi and NFT ecosystems. I recently staked a portion of my ETH on Lido to earn passive income. I believe Ethereum has long-term potential due to its developer activity, network upgrades (like Dencun), and institutional interest. It’s one of the few altcoins I consistently keep in my portfolio.
