Frequently asked questions.

How does Bitcoin security work?


Bitcoin security is easier than you might think — it’s all about keys.

To spend bitcoin, you need access to your private key. At Casa, we shield your bitcoin with multiple keys. If you lose a key from theft or disaster, we can use the others to help you recover your bitcoin. This redundancy and distributed security is superior to leaving your bitcoin with a custodian or just one hardware wallet. This way, you can HODL and chill.

How do I create a secure bitcoin wallet?

Security requires a balanced approach. You want to protect against evolving threats while preserving some access so you can safely recover your bitcoin. Sound recovery methods are important because eventually you will want to hand your bitcoin to someone else, whether you spend it or transfer control to your loved ones. As a Bitcoin security company, Casa helps you create protection that is right for you, and we have a variety of plans to meet your needs, including our Bitcoin inheritance plan.

Which bitcoin wallet is the safest?

There are a variety of ways to store your bitcoin’s private key with cold storage (offline) being the best option. If you protect your bitcoin with just one key on an Internet-connected device such as a phone or laptop, your bitcoin is susceptible to attacks.

At Casa, your bitcoin is protected with multiple keys, even stored on a different device in a different location. Most of these keys are secured in cold storage beginning with your hardware wallet of choice. Casa works with popular hardware wallets Trezor, Ledger, Coldcard, and Keystone.
