In terms of metaphors for #cashu nostr:npub1dx5q2el8nd4eh3eg9t2e25fd7zuqg7zxz6ldkc3uzgh66ss2yc6st288sj , this is what I’m thinking (out loud) for newbs.

In terms of privacy it’s like when you go to the atm to withdraw cash, the bank can see how much cash you withdrew (in this case lighting) but not where you are spending the cash (your cashu mint tokens). Should you need to put cash (mint tokens) back into your account, you can deposit cash back to your account via the atm (withdraw tokens to lightning and send out to lightning wallet).

So cashu has great privacy benefits even over and above lightning and is ideal for a community P2P system. I love it
