#BinanceTurns8 Bitcoin (BTC), Binance Coin (BNB), and Ethereum (ETH) are leading cryptocurrencies with distinct roles. BTC, the first decentralized digital currency, is a store of value and peer-to-peer payment system, known for its security and limited 21 million coin supply. ETH powers Ethereum, a blockchain platform enabling smart contracts and decentralized applications (dApps), with Ether as its native currency. BNB, created by Binance, facilitates trading fee discounts and powers the Binance ecosystem, including its blockchain. Together, they dominate the crypto market, offering investment, utility, and innovation, but their volatility requires cautious research before combining in portfolios.
