I don't mean to act harsh, but if you have to ask something as primitive as this... you probably shouldn't be doing options on it. But... maybe this was sarcasm. Still trying to figure that out. In any case, I'm certainly glad I didn't purchase the underly.
Options trading has never enticed me much. Even though they are considerably cheap and easy on the pocket, they lose out the value much faster when compared to other trading instruments. Of what I’ve studied, it falls down by some percentages each day no matter the movement. I do know about brokers who offer the chance to trade on low commissions but then there are full service brokers too who seek high fees. Now that you seem to be trading with Coinbase, do you mind sharing the commission they seek.
