Notes on the Bitkey:

- Easiest setup experience of any wallet I've used

- Hardware feels really solid, nice build quality

- 2/3 multisig with no seed phrase

- Mobile app and server key can authorise small transactions (dollar amount is user configurable)

- Mobile app and hardware device is required to authorise larger transactions

- Email is required during setup to facilitate recovery if mobile phone / hardware device is lost

- Phone number is optional (from memory)

- Can integrate Cash App / Coinbase for direct purchases to the wallet

- Block can see your transaction data

The app / hardware device is still in beta, however the simplicity of the setup process is near perfect.

While most of us will still prefer a Coldcard, Passport or Jade, those devices aren't for everyone.

I suspect Block will advertise via Cash App and sell a ridiculous amount of these devices, which is great for self-custody but comes at the expense of privacy.

Most importantly, this is not a wallet for your KYC-free corn.
