$BTC Bitcoin is the first and most well-known cryptocurrency, created in 2009 by an unknown person (or group) using the name Satoshi Nakamoto.

It’s a digital currency, which means there's no physical coin—it's all online.

Bitcoin runs on blockchain technology, which is like a public ledger that records every transaction.

It's decentralized, meaning no single bank or government controls it.

People can use BTC to buy things, invest, or send money across borders.

Transactions are verified by a process called mining, where powerful computers solve complex math problems.

BTC has a limited supply only 21 million will ever exist which helps drive its value.

Its price is very volatile, so it can rise or drop quickly.

Many see Bitcoin as digital gold used more as a store of value than for daily spending.

It’s changing how we think about money and finance.
