This is like off-topic for now, but I've noticed there are two kinds of betters:
- Those who bet on the outcome that determines who wins and who loses
- Those who bet on the other betters being stupider/brainwasheder/malinformeder then I
- Yes, the latter "invest" in "derivatives" which basically are bets on the rise or decline in values of other bets: futures, options, and so forth.
