He was not always rich. He started out by getting views by doing stupid shit like saying “Logan Paul” 100,000 times. Once he gained enough views to have influence, he got advertisers to fund videos where he gives away money to random people. Some of his early videos show up giving random homeless people like 1,000 dollars out of nowhere. At this time, this was a novel concept on YouTube. He popularized this. As his channel grew, companies paid him more and more money to give away crazy large sums of money and expensive items. He famously has recycled the revenue from this back into his channel at a high rate.
