I'm bullish AF for the bitkey and am fortunate to know a wizard that made the magic happen.
I think the custody model is a beautiful way to illustrate the capabilities of bitcoin with an easy to use setup/interface.
But it's technically nuanced enough of a product that the technically curious will ask "how does this do the things it does?".
This will help them come to find other signer and client software projects in the space. When they see it doesn't do the things they thought it totally could do, some will be motivated to "do it better" and the things get cooler.
Is this what nerd sniping is? I always hear it but never had it explained.
