Bitcoin is the world’s first and most popular cryptocurrency (digital or virtual currency). Launched in 2009 by an anonymous person or group using the pseudonym Satoshi Nakamoto, it operates without the control of any central bank, government, or middleman (like PayPal or Visa).
Key Features of Bitcoin
1. Decentralization
Bitcoin works on a peer-to-peer network. Transactions are made directly between users, and the network is run by thousands of computers worldwide rather than a single company or government.
2. Blockchain Technology
Every single Bitcoin transaction is recorded on a public ledger called the blockchain. This ledger is completely transparent and immutable (meaning it cannot be altered or faked).
3. Limited Supply ($BTC is Scarce)
There will only ever be 21 million Bitcoins created. This fixed supply makes it similar to "digital gold," because, unlike traditional money (USD, BDT), governments cannot just print more of it, which protects it from inflation.
4. Halving Events
Approximately every four years, an event called the "Halving" occurs, which cuts the reward for mining new Bitcoins in half. This reduces the rate at which new $BTC enters circulation, increasing its scarcity.
How Does It Work?
Mining: New Bitcoins are generated through a process called "mining." Powerful computers solve complex mathematical puzzles to verify transactions and secure the network.
Wallets: To store and use Bitcoin, you need a digital wallet (like a mobile app, software, or hardware device). Every wallet has a public address (like a bank account number) and a private key (like a password).
What is it Used For?
Digital Gold / Investment: Many people buy and hold $BTC as a long-term investment, hoping its value will increase over time.
Global Money Transfer: It allows anyone to send money anywhere in the world quickly, securely, and with relatively low fees.
