I'm mildly nervous about supporting eCash on Alexandria, as I worry that less-informed users will get rugged and think it was our app.

Nobody seems to know that eCash isn't Lightning, and therefore is decoupled from Bitcoin. It's tokens/coupons/IOUs issued by someone with a Lightning node.

We also want to serve people with very little money. What if they earn what is to them quite a few sats, and then watch it just disappear?
