So in the argument discussed in this topic, OP picking up a paper wallet worth 0.6btc, is this a theft scenario? because if we look at OP's story, he wants to return it to the real owner but he doesn't know how.
And I think it will be difficult to return it to the real owner because many opportunists will pretend that the paper wallet is theirs. Then for crypto enthusiasts, we know that Bitcoin is not fake money, because it can be converted into real money, not just touched physically.
No, I'm talking theoretically since I'm talking about the morality of something rather than this specific occasion. It was pretty much summed up that there was no theft, and some users speculated that this could've been a scam attempt, which it might have well been. However, I wanted to reference that this is actually a really difficult situation to be in, and personally I don't know what I would've done. Like I said above, I probably wouldn't have even checked if the wallet had any Bitcoin in it, which could've been a waste of my time trying to find a owner of a wallet that has nothing in it.
