Billion $ idea "The doomsday zap".

Usecase:

You have information that can bring down the worlds governments this information is encrypted. You have to send 10,000 sats every 24 hours from a certain address to a certain address otherwise it is decrypted and posted on Nostr.

Not only can the governments not kill but you can ask for a per diem from them.

The decrypt method is destroyed with the following simple formula "your age + X years" whatever gets you to 95% of your useful life span is X.
