.... right. They did not make money on Bitcoin or get scammed by a different cryptocurrency....
We can check with them if they got scammed by a Nigerian prince while we're at it. If you think you're making some sort of point.
Maybe we should check if they got scammed because their computer had a bunch of viruses.
Or if they were selling something online and the buyer sent them a confirmation code.
There are lots of things they didn't do.
