What would you do if you managed to come across someone else's private key and it's worth an amount that most people would 'prefer not to lose', assuming you have no [idea who it belongs] to or [location clues]? Eg. Sweeping through common books' text for BIP39-based keys.
I suppose you could send a dollar's worth to a different address and hopefully they'd get the hint.
If that really happened, I think that day is the most unlucky day for the owner of the key.
No one wants to even deliberately to remove it right?.
If I find it, of course it will do various ways to find the owner.
If I still can't find it I'll just keep the key.
Just secure it and do nothing to the funds stored there.
I assume the owner must still have a copy of the access key.
And if he realizes he has lost the key, he will definitely back up or move the funds in it.
I just think if we lose the private key, we will immediately back up or move funds there.
If someone misuses the private key, of course we will be very annoyed and curse the person who took our money, right?.
