Sports betting is a disastrous business. when you lose large sums (and you lose), you want to win back, which leads to even bigger losses. Remember, people are playing, not numbers. and no casino and no bookmaker will work in the negative.
as for acquaintances, there is one such, we studied together at the university at the university. he lost so much that his family did not want to communicate, immediately covered the debts, and then realized that it was easier not to communicate with him. that's such a terrible story((
