Bitcoin Guide
Bitcoin is the first decentralized cryptocurrency. It runs on a public ledger called the blockchain, is secured by proof-of-work mining, and has a fixed supply of 21 million coins. This guide explains how it works, what drives its price, and how to get started.
What Is Bitcoin?
Bitcoin is a digital currency that operates without a central bank or single administrator. Transactions are verified by network nodes through cryptography and recorded on a public, distributed ledger called the blockchain. It was created in 2009 by an anonymous person or group known as Satoshi Nakamoto.
How Does Bitcoin Work?
Bitcoin uses a proof-of-work consensus mechanism. Miners compete to solve complex mathematical puzzles to validate transactions and add new blocks to the blockchain. Each block contains a set of transactions and a reference to the previous block, forming an unbreakable chain.
What Drives Bitcoin's Price?
- Supply and demand — The fixed 21 million supply cap creates scarcity. Demand increases when more investors, institutions, or countries adopt it.
- Regulatory news — Government decisions on regulation, bans, or adoption move the price significantly.
- Macro conditions — Interest rates, inflation expectations, and dollar strength affect Bitcoin as a risk asset and inflation hedge.
- Institutional adoption — ETF approvals, corporate treasury allocations, and payment integrations drive large-scale demand.
- Market sentiment — Social media trends, fear and greed indices, and on-chain metrics influence short-term price swings.
How to Get Started
- Choose a reputable exchange or self-custody wallet.
- Verify your identity (KYC) on the platform.
- Fund your account with fiat currency.
- Buy a small amount to start — you do not need to buy a whole Bitcoin.
- Store your Bitcoin securely — consider a hardware wallet for larger amounts.
Key Risks
- Price volatility — Bitcoin can swing 10–30% in a single day.
- Regulatory risk — Governments can restrict or ban cryptocurrency trading.
- Security risk — Exchanges can be hacked; self-custody requires technical care.
- No consumer protection — Transactions are irreversible and there is no FDIC insurance.
