From my understanding of Implied volatility (IV), high IV means the stock price will fluctuate in a wider price range. This is compared to low IV where the stock price will fluctuate in a tighter price range. Therefore, one would think if you are a option buyer, you would favour option that have a high IV so as to increase the probability of your chosen strike price being hit. Likewise, if you are a option seller, you would favour options that have a low IV so as to decrease the probability of the strike price being hit. However, it seems that the options buyers prefer options with a low IV and options seller prefer options with a high IV. Most grateful someone can explain this logic to me.
