What is Bitcoin?

Bitcoin (BTC) is the first and most popular cryptocurrency, created in 2009 by a mysterious person (or group) using the name Satoshi Nakamoto. It's a decentralized digital currency, meaning it’s not controlled by any government or bank.

How Does It Work?

Bitcoin runs on a blockchain—a public, digital ledger where all transactions are recorded.

It uses proof-of-work (PoW), where miners solve complex math problems to validate transactions and earn new bitcoins.

The total supply is limited to 21 million bitcoins, making it deflationary (value can go up as supply stays fixed).

Why Is Bitcoin Important?

Freedom: Send money anywhere without banks.

Security: Hard to hack due to its decentralized nature.

Store of Value: Often called "digital gold" because many people buy and hold it as an investment.

Fun Fact:

The first real-world Bitcoin transaction was in 2010, when someone bought two pizzas for 10,000 BTC. Today, that would be worth millions of dollars!
