Options for individual stocks

options have formulas and I don't understand how you can price these options. and still have speculators. the price for these options are 'irrational' for speculation purposes.
if you are bearish just do straight short. and long just buy the stock. the options are not worth it. and who would buy it.the premium is 10% for out of money options for calls. and depreciate in value

If that’s true then sell them, instead of buying. Many people never buy options and only sell them. Many people also trade combinations of options.
 
Because an options trader ignores that expiration stuff and is focused on a daily granularity. An option 3 months out or 3years out is really just 5.3 of one or half a dozen of the other. Options, are all just Greek to me.
