Frequently asked questions.

Why is it risky to leave your bitcoin with a custodian?

+

Not your keys, not your problem, right? More like: not your keys, not your bitcoin.

Bitcoin custody is different from custodying other assets. When you allow someone else to custody your bitcoin, the same threats that face you as an individual still face those entities, but you no longer have control over steps you take to stop them. Custodial services actually carry their own unique threats to your bitcoin:

Internal attacks within the custodial organization
External attacks incentivized by the custodian holding funds of several people
Organizational bankruptcy and legal action
Collusion against you by the custodian


That’s just the tip of the iceberg, and if it still feels safer, it’s because ignorance is bliss.

What’s the difference between custodial and non-custodial wallets?

+
Due to the sheer amount of threats to one’s bitcoin, many bitcoin holders will opt for a custodial wallet—one where someone else owns the associated private keys—in an effort to shoulder less risk. If a custodial solution (e.g., an exchange, family office, wealth fund, lender, etc.) holds your bitcoin, it’s their responsibility to secure it.

Unlike custodial bitcoin wallets, a non-custodial bitcoin wallet is one in which you own the associated private keys. By using a non-custodial bitcoin wallet, you gain the freedom to do as you wish with your bitcoin while simultaneously taking on the responsibility of securing it. This is why non-custodial wallets are often called self-custody.

Although it may seem daunting at first, self-custody eliminates third-party risk and ensures that only you have access to your funds. With the right tools, self-custody becomes every bit as convenient as a custodial service, yet significantly more secure. At Casa, we believe self-custody is the best type of Bitcoin custody.
