With the transition to Ethereum 2.0 and proof-of-stake, the network became more energy-efficient and scalable. ETH is not just a currency but fuel for innovation in Web3. As adoption grows and more use cases emerge, Ethereum’s influence continues to expand. Many investors and developers see ETH as the future backbone of the decentralized internet.
