$ETH Ethereum ($ETH) is revolutionary, but it is far from perfect. Its transition to Proof of Stake reduced energy consumption, but it also centralized validators in a few hands. Additionally, gas fees remain absurd during times of high demand, which alienates average users. Yes, its DeFi and NFT ecosystem is huge, but competition like Solana or even Bitcoin with its new protocols is advancing quickly. Is it really the future of decentralized finance or just a phase before another blockchain takes its place? That is the real debate.
