It's a good point. He might have ruined his "brand" in some ways, but he always kept some people believing he's some sort of super genius, the kind of people that think intelligence is directly proportional to your net worth.

He does some super cringe shit trying to pretend he's a genius online and most don't fall for it, but as long as some wealthy people do, he'll continue to have his brand.

Also his stocks have made some people rich, are usually way overvalued, so even people that hate the fuck usually know not to bet against his stocks. He is pretty good at blatantly manipulating the fuck out of the market no matter what the news cycle is, and he never suffers consequences.
