Cryptocurrency Basics

A Bitcoin address is a string of letters and numbers used to receive BTC, not a private key. Here’s how to spot common formats and avoid mistakes.

Where is bitcoin? Not in your phone or wallet app. Bitcoin exists as records on the blockchain, and your key gives you control over it.

0.46 bitcoin means a BTC amount, not a fixed dollar value. Learn the unit, how it can be divided, and the mistakes beginners make.

Bitcoin utility means using Bitcoin for transfer, savings, and open settlement. It has real use, but it is not a catch-all payment tool.

Bitcoin is not a stablecoin. Its price floats with market demand, while stablecoins are built to track a reference asset.

The maximum number of bitcoins is 21 million. That cap is built into Bitcoin’s rules, though active circulating supply can be lower.

Why is Bitcoin so expensive? Its price comes from fixed supply, market belief, security, transfer utility, and long-term demand.

This guide to bitcoin explains what BTC is, how it works, how to buy and store it, and what beginners should watch out for.
