What is Bitcoin?

Bitcoin is the world's first decentralized cryptocurrency, created in 2009 by the pseudonymous Satoshi Nakamoto. Here's everything you need to know.

Bitcoin (BTC) is the world's first and most valuable cryptocurrency. Created in 2009 by the pseudonymous Satoshi Nakamoto, Bitcoin introduced the concept of a peer-to-peer electronic cash system that operates without banks or governments. Today, it is widely regarded as digital gold and a store of value.

Key Takeaways

  • Bitcoin is a decentralized digital currency with a fixed supply of 21 million coins.
  • It uses blockchain technology to record all transactions transparently and immutably.
  • Bitcoin can be bought, sold, and stored on exchanges like Tirixax or in personal wallets.

How Does Bitcoin Work?

Bitcoin operates on a distributed ledger called the blockchain. Every transaction is broadcast to a network of nodes, verified by miners using proof-of-work, and permanently recorded in a block. This process ensures that no single entity controls the network and that transactions cannot be reversed or altered.

Bitcoin Mining

Mining is the process by which new Bitcoin transactions are verified and added to the blockchain. Miners compete to solve complex mathematical puzzles, and the winner earns newly created Bitcoin as a reward. This process also secures the network against attacks. The Bitcoin halving event, which occurs every four years, cuts the mining reward in half, reducing the rate of new supply.

Bitcoin's Fixed Supply

One of Bitcoin's most important properties is its fixed supply of 21 million coins. Unlike fiat currencies that can be printed indefinitely, Bitcoin's scarcity is enforced by code. As of 2025, over 19.5 million BTC have already been mined, leaving fewer than 1.5 million left to be issued.

How to Buy Bitcoin

  • Create an account on a crypto exchange like Tirixax.
  • Complete identity verification (KYC).
  • Deposit funds via bank transfer or card.
  • Search for BTC/USDT and place a buy order.
  • Store your Bitcoin in a secure wallet.

Closing Thoughts

Bitcoin remains the cornerstone of the entire cryptocurrency ecosystem. Whether you're a long-term investor or a curious newcomer, understanding Bitcoin is the essential first step in your crypto journey. Its combination of scarcity, security, and decentralization makes it unlike any asset that has come before.
