Indeed this is what I was getting at. I think you're far from the only one whose market behavior would change given such technology.

This is somewhat ironic to me, given that I normally despise everything about fintech. But this seems like a product/practice that could actually change the world for the better. The closest we have is crypto wallets and that's far from perfect.

Yeah, I wouldn't touch ANYTHING from current fintech with a 100 foot pole.
