Could be in any context. I do it a little on UFC fights but that’s a relatively low amount and I can afford I to lose any time I do. It seems like it’s becoming a really wide spread problem though, at least in the US. At the same time I don’t see why it should be illegal. Granted I also don’t think any drug should be illegal.
There are many types of fantasy sport that are not just fantasy football. Also, it depends where the cash prize comes from, is it from people putting money into a pot? Or is it from the league itself as part of marketing and players only stand to benefit and don’t stand to lose?
Another part of fantasy sport is that I think generally speaking, I don’t think it has a focus on winning the prize, it’s a focus on the entertainment value of the fantasy sport itself. Whereas the entertainment value of gambling is directly tied to winning.
