Mr beast is a content creator.

He spends money on his videos, because people will watch them.

He has studyed the YouTube algorithm and had learned to use it to his advantage.

If you notice his videos can be watching a year from now and still be relevant.

This is his goal. Continuous watch time.

Is he a show off? I don't think so. He can do whatever he wants with his money. It's probably a tax write-off!

Is he kind an generous? Probably more likely. He does help a lot of people with his videos.
