Bitcoin (BTC): The First Cryptocurrency
Bitcoin (BTC) is the world’s first and most popular cryptocurrency. It was created in 2009 by an unknown person or group using the name Satoshi Nakamoto. Bitcoin allows people to send and receive money over the internet without using banks or other financial institutions.
What is Bitcoin?
Bitcoin is a digital currency, which means it exists only online. Unlike traditional money such as dollars or taka, Bitcoin is not controlled by any government or central bank. Instead, it works on a technology called Blockchain, which records all transactions in a public and secure digital ledger.
How Bitcoin Works
When someone sends Bitcoin to another person, the transaction is verified by computers around the world. These computers are run by people called miners. Miners solve complex mathematical problems to confirm transactions and add them to the blockchain. As a reward, they receive new Bitcoin.
Advantages of Bitcoin
Decentralized – No single authority controls it.
Fast global transfers – You can send Bitcoin anywhere in the world.
Limited supply – Only 21 million Bitcoins will ever exist.
