This is what I see at IB a few instants ago. Option price is being settled by .80. So if you sell now you get a profit of .30.
With so little time for expiration there is no time decay value. The price of the option will be closer and closer to (expiration strike) - (underlying price), which right now is 3.5 - 2.78 = 0.72.
If you think it will continue to tank at least 0.08 down more you can wait. Otherwise sell it.
