A guaranteed result is boring. No, it’s great, it’s good, but everyone likes that when they’re buying, say, a chair. I want a blue chair of a specific size for my living room.

Even all these promo codes like this one https://washingtonbeerblog.com/csgoroll-promo-code-gamble-csgo-for-beer-lovers-3-free-cases-10-deposit-bonus/ are based on the same thing. You don’t know what you’re going to get yet, everything is unpredictable, and that’s what attracts people.
