Bitcoin in a Nutshell
Bitcoin is a form of digital currency that allows people to send and receive money without going through a bank, government, or any middleman. Instead, it uses a technology called blockchain—a secure, transparent, and decentralized digital ledger that records all transactions.
Launched in January 2009, Bitcoin was the first-ever cryptocurrency, and to this day, it remains the most popular and most valuable one.
