Bitcoin wallets are software or hardware that manage your Bitcoin private keys. Understanding wallets is essential for safe Bitcoin usage.
A Bitcoin wallet doesn't actually store Bitcoin - it stores the private keys that control Bitcoin addresses on the blockchain.
Hot wallets are connected to the internet (mobile apps, desktop software, web wallets). They're convenient but less secure.
Cold wallets are offline (hardware wallets, paper wallets). They're more secure but less convenient for frequent transactions.
Custodial wallets are controlled by a third party (exchanges, banks). You don't control the private keys.
Non-custodial wallets give you full control of your private keys. This is true Bitcoin ownership.
Popular wallet types include mobile wallets (BlueWallet, Electrum), hardware wallets (Ledger, Trezor), and full nodes (Bitcoin Core).
