Bitkey vs GrossUp

Bitkey is the safe, simple, and secure way to own and manage your bitcoin. It's a mobile app, hardware device, and a set of recovery tools all in one wallet. Bitkey is a 2-of-3 multi-signature wallet which means there are three private keys protecting your bitcoin. You always need two out of three keys to sign a transaction, giving you extra protection. If you hold bitcoin with an exchange, you don't control it. With Bitkey, you hold the private keys and control your money. Recovery Bitkey recovery tools help you recover your bitcoin if you lose your phone, hardware, or both, without needing a seed phrase. Device verification Verification on your Bitkey device provides an additional layer of security for confirming transfers and critical settings. Privacy Keep your balance and transactions private, with protections to ensure that everyone else — from onlookers to our servers — stays in the dark. Inheritance Put an inheritance plan in place for your bitcoin, with a process that’s simple to set up and secure by design.
