This is worlds better than casinos, sports betting, or any other form of gambling, IMO.
People are entertained through watching or participating and some are making big dollars.
My kids watch his videos because the algorithm feeds it to them and from what I’ve seen, I’d rather they be watching MrB than ads for DraftKings where they might believe that some day in the future their free $500 will make them rich. Or worse yet: state lotteries selling a dream for $2 and making millions off the stupidity of those who don’t understand basic stats because the education the lottery is supposedly funding doesn’t do a very good job.
YMMV.
