Payment option: Cashu

[taoeffect]

Problem

We don't support Bitcoin yet.

Solution

Cashu is an interesting potential solution. It is custodial in the sense that you have to trust that the mint that you sign up with doesn't run away with your bitcoin. So it's mainly good for small payments. However, it offers better privacy than Lightning even, and can be used completely offline (once you get the "ecash"). It does require first sending a lightning payment to a mint to mint your ecash. To send payments across mints it requires some swapping through lightning (and an internet connection) to work.
