$ETH Ethereum, the second largest cryptocurrency by market capitalization, is much more than a digital currency. It is a decentralized platform that powers thousands of applications, from decentralized finance (DeFi) to non-fungible tokens (NFTs). Its smart contract technology enables automated and transparent agreements without intermediaries. After its "merge" in 2022, Ethereum became more energy efficient. Its vibrant ecosystem continues to expand, exploring new frontiers in blockchain technology and redefining the way we interact with the digital world.
