Bitcoin (BTC) is the world's first and most famous digital currency. It was created in 2009 by an unknown person or group using the name Satoshi Nakamoto.
Unlike regular money, Bitcoin is not controlled by any government or bank. It runs on a technology called blockchain, which is a public ledger that records every transaction. This makes Bitcoin secure and transparent.
Key features of Bitcoin:
· Decentralized: No single person or institution controls it.
· Limited supply: Only 21 million Bitcoins will ever exist.
· Global: You can send Bitcoin anywhere in the world quickly.
· Pseudonymous: You don't need to use your real name.
Why do people use Bitcoin?
Some use it as an investment, hoping its value will rise. Others use it to buy goods and services online. In some countries, people use Bitcoin to protect their savings when local currencies lose value.
Risks of Bitcoin:
· Its price is very volatile (goes up and down sharply).
· It's not widely accepted by shops yet.
· If you lose your private key, you lose your Bitcoin forever.
In short, Bitcoin started the digital currency revolution. While it has risks, it remains the most trusted and valuable cryptocurrency in the world.
