Options, to put it simply, are like collecting rent over time. If you're the buyer, watching that candlestick like waiting for takeout, the time value chips away at your pocket every day; if you're the seller, it looks like collecting rent as a landlord on the surface, but secretly you're afraid the house will catch fire in the middle of the night—when the market goes crazy, all the rent you've collected before goes into covering losses, which isn't enough.

Recently, the "compound yield" from pledging and sharing security has been criticized as a scam, and I see it kind of like the seller's mindset: constantly treating time as a moat, thinking volatility won't come knocking. Anyway, I won't bother explaining anymore; if the market wants to be random, let it be. I only remember the last thing: don't get caught with a knife, especially when you think you're just collecting rent.
