Bitcoin Wallet Basics
Bitcoin (BTC) is a decentralized digital currency where transactions are recorded on a public distributed ledger called the blockchain. To use Bitcoin, you need a digital wallet to store and manage your BTC. Each wallet contains one or more unique Bitcoin addresses for sending and receiving funds.
Wallets fall into two main categories:
- Hot wallets: Connected to the internet for convenient trading (lower security)
- Cold wallets: Offline storage with enhanced security (less convenient for frequent transactions)
Understanding how to safely generate and use receiving addresses is essential regardless of wallet type.
What Is a Bitcoin Receiving Address?
A Bitcoin receiving address is a unique alphanumeric string that allows others to send BTC to your wallet. Think of it like a bank account number, but with these key differences:
- Composed of letters and numbers (case-sensitive)
Multiple format options:
- P2PKH (Legacy): Starts with "1"
- P2SH (SegWit): Starts with "3"
- Bech32 (Native SegWit): Starts with "bc1"
Different formats may affect transaction fees and compatibility. Modern wallets typically support all formats.
