sending bitcoin over bluetooth between bitchat android and iphone. both have a native cashu ecash wallet built in. the ecash travels directly from phone to phone. the sender needs no internet. like instant and untraceable digital cash. it's going to be insane. work in progress with @npub1qjgc...lgjw , @npub1f742...rpa3, @npub1zqsu...cqrs , @npub1ce7d...3d7m , @npub1dvdc...d4rm et al.
