$BTC Bitcoin (BTC) is a decentralized digital currency that was invented in 2008 by an unknown person or group using the pseudonym Satoshi Nakamoto. It operates on a peer-to-peer network without the need for intermediaries like banks. Transactions are verified by network nodes through cryptography and recorded on a public ledger called the blockchain. Bitcoin is often seen as a store of value or "digital gold" due to its limited supply of 21 million coins. It has sparked global interest in cryptocurrencies and blockchain technology, influencing the development of thousands of other digital assets and financial innovations.

$ETH Ethereum (ETH) is a decentralized, open-source blockchain with smart contract functionality. It enables developers to build and deploy decentralized applications (dApps) and is the foundation for many innovations like decentralized finance (DeFi), non-fungible tokens (NFTs), and DAOs. Launched in 2015 by Vitalik Buterin and others, Ethereum introduced the Ethereum Virtual Machine (EVM), allowing code to run on a global network. Ether (ETH) is its native cryptocurrency, used to pay for transactions and computational services. Ethereum transitioned to proof-of-stake (PoS) in 2022 with the Merge, making it more energy-efficient and paving the way for future scalability upgrades.
