Dogecoin millionaire

I went down the rabbit hole of watching these youtubes of the dogecoin millionaires who were in poverty and somehow managed to put a few grand into it and it exploded making them millionaires. They appear to be geniuses and you listen to them. Until you find out after every other prediction they make is wrong it was PURELY luck and they arent these geniuses that you think.

This got me reading about this kind of stuff and apparently experts are often wrong and there has been studies suggesting people with very limited knowledge can often predict things better than an expert in that field. And for some reason the experts are not seemingly held accountable for being wrong over and over.
