The largest individual youtuber in the world. He has several channels, the main ones are Mr.Beast and Mr.Beast philanthropy.
I think the main selling point of youtube is watching people do things you cannot, either due to time, expertise, or money. Mr.Beast kinda personifies that, as many of his videos cost over $1M to make and are original owing to nobody else being able to make them, ala 'I made a lazer dungeon, first person to reach the end wins $500k' .
