Frequently asked questions.

How do I purchase bitcoin with Casa?

You can purchase up to $250,000 per year directly through your Casa App via our processing partner. For large purchases ($100,000 and up), our Client Advisors work directly to connect you with the right liquidity partner.

How does multi-signature technology work?

"Multisig” is short for "multi-signature," and it means that spending funds requires more than one approval signature.

We use battle-tested, open source, pay-to-script-hash multisig technology that has been live on Bitcoin since 2012, and today is protecting over 5 million BTC. For a full explanation of how Casa uses multisig, visit our
explainer page.

If something were to happen to Casa, are my funds still safe?

It’s our responsibility to help you prepare for all situations, even catastrophic scenarios. In the event that Casa is ever unreachable, your funds are safe and can be accessed using open source software. We’ve designed it this way so that you can always access your coins, no matter what. We provide all clients with step-by-step instructions to make this process simple and straightforward. We call these the Casa Sovereign Recovery Instructions, and even rehearse this process upfront with our Platinum and Diamond clients.

Is there a limit to how much bitcoin I can keep with a Casa membership?

Though there are no technical limits to the amount of bitcoin you can store with Casa, we recommend the following amounts for each membership level. Gold: $1,000 - $75,000. Platinum: $75,000 - $500,000. Diamond: over $200,000.

Who are Casa's investors?
