Bitcoin is a type of digital currency, also known as a cryptocurrency. It was invented in 2009 by an unknown person or group using the pseudonym Satoshi Nakamoto. Here’s a simple breakdown of what it is:
🔹 Key Features of Bitcoin:
Decentralized: No government or bank controls it. It's run by a network of computers around the world.
Limited Supply: Only 21 million bitcoins will ever exist, which makes it scarce like gold.
Blockchain Technology: All transactions are recorded on a public, digital ledger called the blockchain.
Pseudonymous: Users don't need to reveal their identities; they use digital addresses.
Divisible: You can use fractions of a bitcoin. The smallest unit is a satoshi (0.00000001 BTC).
🔹 How People Use Bitcoin:
As a store of value, like gold.
To send money across borders without banks.
As an investment, hoping its price will rise.
For payments, at places that accept it.
