Unlike traditional money issued by governments, cryptocurrencies are decentralized and typically run on blockchain technology—a distributed ledger enforced by a network of computers. Bitcoin, launched in 2009, was the first and remains the most well-known crypto. Other popular ones include Ethereum, Solana, and Binance Coin. Cryptocurrencies offer fast, borderless transactions and can serve as investment assets, though they are highly volatile. While they promise financial innovation and autonomy, concerns around regulation, security, and environmental impact remain key challenges in mainstream adoption and long-term sustainability.
