It would crash before you could sell it. Guarantee major market makers are watching these wallets specifically, and autonomously.

So if someone figures out how to do it, they then effectively have a button that destroys a massive amount of wealth worldwide owned by a pretty specific group of people? That's fascinating, with billions of dollars at stake people would absolutely kill for that, not to mention the governments that use crypto on a macro scale for avoiding sanctions etc. Would probably make a really good thriller.

My theory: The wealth would probably effectively transfer to holders of other currencies. You aren’t really destroying wealth by destroying currency; the supply of stuff is still available. Just now the demand for it from crypto-holders is gone, so it’d get cheaper for USD-holders.
