I think this is a trick to get attention. Because in order to have such a huge fortune (over $ 2 million), every transaction needs to be very careful and carefully checked, so that confusion is not possible. Therefore, I still think this is just a way to draw attention to crypto
Of course, with this kind of mistakes and as blockchain is transparent, sooner or later it will draw some attention. But I doubt that it was done by mistakes, this is very shady and the only reason that this individual did this is to hide something and colluding or conspiring with the miners with his illegal wealth here. Very intelligent move, but sorry everything is being seen in blockchain.
