Ethereum is one of the most famous cryptocurrencies in the world, and is considered more than just a currency; it is a platform that allows developers to create decentralized applications using smart contracts. It was launched in 2015 and is known for its flexibility and scalability. A large number of projects in the field of decentralized finance (DeFi) and NFTs rely on it. The network has evolved to become more efficient thanks to continuous updates, such as 'the merge' which significantly reduced energy consumption. Ethereum is not just an investment tool, but a revolutionary technological foundation.
