In the past few days of analyzing options positions, I increasingly feel that time value is quite "realistic": buyers spend money to buy possibilities, but time is deducting points every day; sellers collect certainty, but once there is a big fluctuation (especially around upgrades/hard forks when everyone is guessing whether to migrate or not), they might lose all the gains they previously made. To put it simply, who time value eats depends on whether you can withstand the "waiting."

I now treat it more as practice: for buyers, consider it as paying tuition, and think in advance about how much you could lose at worst; for sellers, see it as earning interest, but keep the position light, set stop-losses in advance, otherwise, if the chain suddenly acts up, the first to panic will definitely be yourself.
