What is a Bitcoin Wallet?
A Bitcoin wallet is a software or hardware tool designed to store the cryptographic keys for Bitcoin addresses, enabling users to send and receive BTC. Contrary to popular belief, Bitcoin wallets don’t store coins but manage access to them via private keys.
Types of Bitcoin Wallets
Desktop Wallets
- Installed on computers (e.g., Bitcoin Core, Electrum).
- Offer full control over keys but require sufficient storage for the blockchain.
Mobile Wallets

Hardware Wallets
- Physical devices (e.g., Trezor, Ledger).

Web Wallets
