Yea the denominations are pretty big. They have to be because it's main net. It would be cool to see something like this with smaller denominations (in sats) as eCash or Lightning somehow.
Lots of experimentation with #cashu created by nostr:npub12rv5lskctqxxs2c8rf2zlzc7xx3qpvzs3w4etgemauy9thegr43sf485vg. This project is an experiment, too.
