My previous misunderstanding about options was: the buyer is just spending a little money to take a gamble, losing means admitting defeat, winning doubles, pretty exciting. Now I understand, to put it simply, the time value is "deducting your salary" every day, even if you're the buyer and do nothing, you will gradually become unprofitable unless the market moves fast enough; the seller looks like collecting rent, but actually they are exchanging tail risk for a little bit of time premium, and when a black swan hits, they just take the hit... I, with social anxiety, only dare to try small positions, don’t let me play the "steady profit" persona. Recently, before and after the main public chain upgrade/maintenance, the group has been guessing whether projects should migrate, I just want to say: if you're the buyer waiting for news, you'll be eaten by time first; if you're the seller laughing too early, you might also be countered when the news explodes. That's all for now.
