I only recently realized that options, to put it simply, are a tug-of-war with time: the buyer is constantly being eaten away by time value, and even when the market is stagnant, they're losing money; the seller seems to be "making easy money," but in reality, they're betting on no surprises, and once volatility actually hits, they have to scramble to cover their margin. The funniest part is that many people only focus on the direction, but in the end, they lose to "not moving."

By the way, I was a bit slow to realize that the economic collapse of blockchain games is similar: inflation + studio output flooding, when the coin price drops, it spirals downward... It's somewhat like the options buyer, where time (selling pressure) keeps eating at you, but you still think you're just playing a game. Anyway, now whenever I see the words "guaranteed profit," I tighten my wallet first.
