Quick guide: cold wallets and hot wallets
Cold wallets can also send transactions: sign the transaction on an offline device, then pass it to an internet-connected device to broadcast.
Your assets are always recorded on the blockchain; the wallet only safeguards the private keys used to access them.
Store assets you won’t touch for a long time in a cold wallet, and keep only a small amount for everyday use in a hot wallet.
Many people put $BTC they plan to hold long-term in a cold wallet and keep the funds they need for everyday use in a hot wallet.
