What is self-custody crypto in simple terms?

Self-custody means you keep your own crypto keys instead of letting an exchange hold them. Think of it like keeping cash in your own safe versus leaving it at a bank. You have full control, but you're also fully responsible for security.

Is self-custody safe?

Self-custody eliminates exchange counterparty risk but introduces personal responsibility risk. If you follow good practices — secure seed phrase backup, hardware wallet for large amounts, never share your keys — self-custody is the safest way to hold Bitcoin.

How is self-custody different from keeping crypto on an exchange?

On an exchange, the company holds your private keys and controls your funds. With self-custody, you hold the keys directly. The exchange can freeze your account or go bankrupt; with self-custody, only you can access your Bitcoin.

Can beginners do self-custody?

Yes. Modern hardware wallets like Ledger and Trezor make self-custody straightforward. The key steps are: buy a hardware wallet, write down your seed phrase on paper (never digitally), and transfer your Bitcoin from the exchange. Most people can set this up in under 30 minutes.

What are the risks of self-custody?

The main risk is losing your seed phrase — if you lose it and your wallet breaks, your funds are gone forever. Other risks include phishing attacks, malware on your computer, and physical theft of your hardware wallet. Proper backup and security practices mitigate all of these.

What Is Self-Custody Crypto?

Self-custody means you hold the private keys to your own cryptocurrency — no exchange, no bank, no third party can control your assets. It is the foundational principle of Bitcoin: be your own bank.

What Is Self-Custody?

Self-custody (also called self-sovereign custody or non-custodial holding) means storing your cryptocurrency using a wallet where only you control the private keys. Your private key is the cryptographic proof that you own your Bitcoin — whoever holds the key controls the funds.

When you keep Bitcoin on Coinbase or Binance, they hold the private keys on your behalf. This is custodial holding. If they get hacked, shut down, or freeze your account, your Bitcoin is at risk. Self-custody removes this counterparty risk entirely.

Self-custody options include hardware wallets (Ledger, Trezor, ColdCard), software wallets (Sparrow, BlueWallet, Electrum), and multisig setups that split key control across multiple devices for added security.

Why Self-Custody Matters

Self-custody eliminates counterparty risk: your funds can't be frozen, seized, or lost by a third party. You get complete privacy with no KYC requirements for receiving or holding Bitcoin. You gain censorship resistance because no one can prevent you from transacting.

The FTX collapse of 2022 is the most prominent example of why self-custody matters. Over $8 billion in customer funds were lost because users trusted a centralized exchange with their private keys. Self-custody would have prevented every single loss.

The traditional tradeoff with self-custody is that you lose access to exchange features like trading, lending, and yield. To trade on a centralized exchange, you typically have to deposit (give up custody of) your Bitcoin first.
