Frequently asked questions
Why choose Bitcoin-only?
Bitcoin-only firmware keeps the experience focused and reduces complexity. It is built for people who want a dedicated bitcoin device rather than an all-in-one crypto wallet.
Is a hardware wallet better than leaving bitcoin on an exchange?
A hardware wallet helps you control your keys. That reduces counterparty risk because you are not relying on an exchange to custody your bitcoin.
What do I need to keep safe?
Your backup words matter more than the device. Store the backup offline and never photograph it or type it into a website or app.
Important notes
- Never share your backup words with anyone
- Do not store backups digitally
- Verify all receive addresses on the device screen before approving
