Did a little circular Bitcoin medium of exchange experiment for back to school supplies.
Bought $200 of Target gift cards which cost 691,870 Sats and gave 3.2% back (22,092 Sats) using nostr:npub18tcc00lqpysdsurg567dllzg7jeyr5wcyk2v6w23rx3s3ygyze2qv32nxx
Immediately bought $200 on nostr:npub1xkere5pd94672h8w8r77uf4ustcazhfujkqgqzcykrdzakm4zl4qeud0en for 679,735 Sats (River has 1.2% fee).
679,735 + 22,092 = 701,827 Sats - 691,870 means +9,957 net additional Sats for me.
Network/gas fees included in the figures above, but it was all done over Lightning ⚡️
