Understanding Cryptocurrency Wallets
A crypto wallet is a digital tool for storing, sending, and receiving cryptocurrencies. It operates via:
- Public Key: Wallet address (shared for transactions).
- Private Key: Secret code granting fund access (never share).
Types of Crypto Wallets
| Type | Description | Examples |
|---------------|--------------------------------------|------------------------|
| Hot Wallets | Internet-connected for quick access | Exodus, MetaMask |
| Cold Wallets | Offline storage for security | Ledger Nano S, Trezor |
| Custodial | Managed by third parties (e.g., exchanges) | Binance, Coinbase |
| Non-Custodial | User-controlled private keys | Trust Wallet, Electrum |
