$ETH
Ethereum started in 2015 as an ambitious project led by Vitalik Buterin, facing widespread skepticism at first. However, its distinction with smart contracts and ability to create decentralized applications gave it tremendous momentum. Over time, it was adopted by companies, and thousands of projects built on it emerged, such as decentralized finance (DeFi) and non-fungible tokens (NFTs). The price of ETH rose from less than a dollar to thousands of dollars, turning its early investors into millionaires. In 2022, it successfully transitioned to a proof-of-stake system, reducing energy consumption by 99%. Ethereum is now the cornerstone of the blockchain world.
