Bitcoin Basics

Bitcoin is the world's first decentralized digital currency. Created in 2009 by Satoshi Nakamoto, it allows people to send and receive money over the internet without needing a bank or payment processor.

Unlike traditional currencies controlled by governments, Bitcoin is secured by a global network of computers (miners) who verify transactions and maintain the blockchain ledger.

Bitcoin runs on a technology called blockchain — a public, distributed ledger that records every transaction. When you send Bitcoin, your transaction is broadcast to the network and grouped with others into a "block."

Miners compete to solve complex mathematical puzzles to add the next block to the blockchain. The first miner to solve the puzzle gets to add the block and receives newly minted Bitcoin as a reward. This process is called "proof of work."

Mining is the backbone of Bitcoin's security. Miners validate transactions, prevent double-spending, and make it extremely difficult (and expensive) for anyone to tamper with the blockchain.

Without miners, Bitcoin couldn't function. That's why miners are rewarded with new Bitcoin — they're providing an essential service to the network.

Bitcoin's value comes from its unique properties: it's scarce (fixed supply), portable (send anywhere instantly), divisible (up to 8 decimal places), durable (digital), and censorship-resistant (no one can block your transactions).

As more people recognize these properties and adopt Bitcoin, demand increases — and so does the price. For miners, this creates an opportunity to earn Bitcoin while it's being minted and potentially benefit from long-term appreciation.
