A curious fact about Ethereum, one of the most famous cryptocurrencies, is that its creation was driven by a young programmer named Vitalik Buterin, who was only 19 years old when he launched the project in 2015. Ethereum not only allows cryptocurrency transactions but also introduced the concept of smart contracts, which are programs that execute automatically when certain conditions are met. This has enabled the development of decentralized applications (dApps) and has revolutionized the way transactions and agreements can be made online.

A little-known crypto term is "DeFi," which stands for "decentralized finance." It refers to an ecosystem of financial applications built on blockchain that allow users to conduct transactions, lending, and savings without traditional intermediaries like banks. DeFi has grown rapidly and has attracted many investors and developers to the crypto space.
