How Does a Change in the Strike Price Affect a Call Option’s Premium?

For a crypto call option, a lower strike price will result in a higher premium, all other factors being equal. A lower strike price means the option is either deeper in-the-money or closer to being in-the-money, increasing its intrinsic or time value.

The option provides a greater potential for profit since the purchase price is lower. This increased value and probability of being profitable translates directly into a higher price for the contract.
