Bitcoin (BTC) is the first and largest cryptocurrency. It launched in 2009 as a decentralized digital asset that can be sent peer to peer without a bank or payment company in the middle.
How Bitcoin works
Bitcoin runs on a blockchain, which is a public ledger of transactions maintained by a distributed network of computers. New transactions are grouped into blocks and confirmed by miners.
Why Bitcoin matters
Bitcoin introduced digital scarcity. Only 21 million BTC will ever exist, which is why many investors describe it as digital gold.
