Bitcoin (BTC) is the first and most well-known cryptocurrency.

Here is a quick overview of what it is and how it works:

1. What is Bitcoin?

Digital Currency: It is a form of digital money that exists only electronically. There is no physical version.

Decentralized: It operates without a central authority like a bank or government. This is its key feature.Created by Satoshi Nakamoto: It was invented in 2008 by an unknown person or group using the pseudonym Satoshi Nakamoto, and its open-source implementation was released in 2009.Finite Supply: There will only ever be a maximum of 21 million Bitcoins created.

2. How Does Bitcoin Work?

Bitcoin is built on a technology called Blockchain:

Public Ledger: The blockchain is a vast, open, and distributed digital ledger that records every Bitcoin transaction ever made. It is shared across a network of computers around the world.

Blocks and Chains: Transactions are grouped into "blocks," and once verified, these blocks are added to the end of the "chain" in a linear, Once a block is added, it is permanent and cannot be altered.

Mining: New transactions are verified and new blocks are added to the blockchain through a process called "mining." Miners (individuals or companies with powerful computers) compete to solve complex mathematical problems (known as "proof-of-work"). The first miner to solve the puzzle gets to add the next block and is rewarded with newly created Bitcoin and transaction fees.

Peer-to-Peer: Transactions happen directly between the sender and receiver without the need for an intermediary like a bank.

3. Usage and Investment

Medium of Exchange: It can be used to send money worldwide or buy goods and services from vendors that accept it.

Investment/Trading: It is a highly volatile asset, and many people buy and sell it on crypto exchanges hoping to profit from its price fluctuations.
