So I'd like to ask you honestly - how is it "fun" when you lose money? What makes it fun - the prediction of what's gonna happen next? The winnings make it fun? But no one can win 100% of the times, right? (except for the house)
I don't get how it could be fun to jump off a bridge with my feet tied to a rope but there are people who pay a lot of money to do that and I don't think they could explain it to me in a way that I could understand.
Gambling is of course different than bungee jumping but adrenaline is there, risk is there, plus the tantalizing expectation of a lucky win. The occasional small win keeps the excitement going. Just make sure to set the max budget and stick to it and you can have a lot of fun for $100. Don't make the rope too long or you'll smack you head into those rocks.
