Does sports gambling follow the general gambling trends? Is U.S. gambling in general lower than in other countries? Might the cultural / religious norms around gambling be the difference? >Basically want to hear what is keeping young, tech savvy and well educated Americans (mostly quants but also similar fields) from earning money on sports betting? By earning money, do you mean by placing successful bets on sports outcomes? Or by creating websites that enable others to bet, and skim off the top? Sports betting seems like it subject to all sorts of potential cheating, like point shaving, doping your athletes/horses, etc.. Maybe crypto seems like it is harder to be cheated? Or maybe gambling seems zero-sum, while the ideal of crypto doesn't?
