OTM options are all extrinsic-value. They are cheap in dollars and expensive in probability: most expire worthless. That is why they attract buyers hoping for a big move and sellers collecting premium.
The further out of the money, the lower the delta and the faster the option loses value as expiration approaches without a move.
Example: stock at $40. A $45 call priced at $0.30 needs the stock to rise more than 12% to $45.30 by expiration just to break even.
