A relatively untapped market is how do we provide people to exchange physical notes for bitcoin in most private way. paper wallets are by far the most frictionless, better than opendimes for this usecase.
Someone should make a mobile wallet that verifiably sweeps paper wallets upon scanning a bar code. A frictionless cash/btc cash market could emerge. These btc paper wallets could truly be cash like exchangeable. nostr:npub1qny3tkh0acurzla8x3zy4nhrjz5zd8l9sy9jys09umwng00manysew95gx, nostr:npub1rtlqca8r6auyaw5n5h3l5422dm4sry5dzfee4696fqe8s6qgudks7djtfs

The instasweep ensures the paper wallet is dead. If the new owner of btc wants to resell/spend, go home & print a paperwallet to resell btc. rinse & repeat.
that is if they don't want to have own mobile phone part of transaction, of course they could just sell on phone but that isn't the point here. needs to mimic cash like as best as possible for some.
