Frequently asked questions
What is a cold wallet?
A cold wallet is a crypto wallet that keeps its private keys offline — usually a hardware device — so it's far harder to hack than an online hot wallet.
What's the difference between a cold wallet and a hot wallet?
A cold wallet stays offline for maximum security, while a hot wallet is connected to the internet for convenient spending and trading but is more exposed to attacks.
Are cold wallets worth it?
For long-term or large holdings, yes — the offline security greatly reduces the risk of theft compared with leaving coins on an exchange or hot wallet.
