Bitkey has made Bitcoin hot. Not because of the tech. Because it’s beautiful, simple, and my wife actually wants it.

I always wanted to get a @Bitkey but never got around to do it so when @JoelBomgar sent me the sats to buy one I couldn't say no. Here's my honest review: The setup was extremely easy, took less than 5 minutes to go from opening the box to receiving my first sats, it's definitely the easiest hardware wallet out there. The UI is world class, I could give this to my mother and she would have no problem setting it up. The lack of a seed can be disorienting at first, but it made me question how much security we actually gain by forcing people to secure both a hardware device and a piece of paper containing 12 words. Probably not much. Yes, there's a level of trust that you need to place in the bitkey team, but as we have seen from the colcard saga unless you build the wallet AND the software yourself, there's always some trust somewhere. In short, bitkey should probably be the first step in your self-custody journey.
