Re-explain

A cryptocurrency wallet is a digital tool that allows users to store, send, and receive cryptocurrencies. It doesn't actually store coins but manages private and public key pairs that control access to blockchain addresses.

Types:

Hot wallets: Connected to internet (mobile apps, web wallets)
Cold wallets: Offline storage (hardware wallets, paper wallets)
Custodial: Third party controls keys
Non-custodial: User controls private keys
