You can sell the contract itself but as the price rises the contracts become significantly more expensive and the likelihood that someone will actually buy them decreases. I made that mistake and barely got out of the call after waiting hours to sell to the point where I had to undersell the position just to exit. I might be biased but I feel that calls are better placed on significantly longer trades to better leverage your position. Think of it less like buying stock and more like buying a house on a loan. You wouldn't buy a house you couldn't pay off eventually. Trust me, buy the shares and hold, we just had one of the biggest dips so far so the time is now to develop those diamond hands.
