But it is an interesting way to scam. Create said address, send funds to it, keep selling the private key.
One problem: the buyer can sell it too

If the person who created this and sent the funds to it sold it 100 times between $500 and $1000 they have made a lot of money.
Second problem: the buyer won't understand how to use this private key, and thus can't easily verify it belongs to that address. Considering OP's history on this forum, I don't think he created this on his own. Which means that whoever created it is spread it already. This address is mentioned
on Reddit in a 2 years old post, but it doesn't add anything. I'm curious what's the story behind this.
