There is a common pitfall in options trading: many people want to act as sellers to "collect rent," but end up continuously subsidizing the market.

Where does the problem lie? Most traders only look at the implied volatility (IV) relative to historical levels to make decisions, but that's not enough. True experts go further—by calculating the post-event volatility premium to determine whether options are truly cheap.

In other words, when you see IV at a high level and think an opportunity has arrived to sell, the market may have already priced in more aggressive volatility expectations. When major assets like $BTC, $ETH experience volatility beyond expectations, the pain begins for your account.

Therefore, in options trading, you should not only pay attention to the absolute level of implied volatility but also understand the logic behind volatility premiums—only then can you avoid the trap of seemingly stable returns that secretly hide huge risks.
