If you are getting into cryptocurrency, you will hear the word “wallet” constantly. But a crypto wallet does not actually “store” your coins the way a physical wallet holds cash. Here is what it really does — and how to choose the right type.
What a crypto wallet actually is
Your coins live on the blockchain, not in the wallet. A crypto wallet stores your private keys — the secret codes that prove ownership and let you authorise transactions. Whoever controls the private keys controls the funds. That is why the phrase “not your keys, not your coins” is repeated so often.
Hot wallets
A hot wallet is connected to the internet — think mobile apps, browser extensions like MetaMask, or the wallet built into an exchange. They are convenient and free, making them ideal for small amounts and everyday use. The trade-off is that being online makes them more exposed to hacks and phishing.
Cold wallets
A cold wallet keeps your private keys completely offline. The most common type is a hardware wallet (such as Ledger or Trezor) — a small physical device that signs transactions without exposing your keys to the internet. Cold wallets are the gold standard for securing larger or long-term holdings.
Custodial vs non-custodial
A custodial wallet (like the one on an exchange) means a company holds your keys for you — convenient, but you are trusting them. A non-custodial wallet means you alone hold the keys, giving you full control and full responsibility, including safeguarding your recovery phrase.
Which should you use?
Most people use a mix: a hot wallet or exchange account for small, active funds, and a cold hardware wallet for serious savings. Whatever you choose, never share your private keys or recovery phrase with anyone, and never enter them on a website.
Protect your recovery phrase
When you set up a non-custodial wallet you receive a 12–24 word recovery phrase. Write it down on paper, store it somewhere safe and offline, and never photograph or type it into a website. Anyone with that phrase can take your funds.
