$ETH ETH is actually quite complex but also very interesting. It's not just a coin; it’s more like the 'fuel' of the entire Ethereum network. All transactions, smart contracts, and DApp operations require ETH to pay transaction fees. Compared to Bitcoin's positioning as a pure 'digital gold', ETH is more utility-oriented. It’s like buying BTC for value preservation, while buying ETH is more for participating in this ecosystem, as DeFi, NFTs, and blockchain games are basically all built on Ethereum.

However, ETH is not without its issues. Previously, the transaction fees were outrageously high, and transferring even a small amount could cost dozens of dollars, which was absurd. Now, although it has transitioned to PoS, which reduces energy consumption and improves efficiency, and ETH 2.0 is gradually being implemented, some people still feel that it has become more centralized. Overall, ETH is a coin with a story and utility that deserves attention, but we shouldn't idolize it. Its competitors like Solana and ARB are also strong, and it’s hard to predict what the future holds.
