being an investor, you should know all the risk you took when you joined the ICO. Why would you sell for a loss after choosing to invest in such project?? you should at least wait for the price to recover up to the ICO price before selling. You should be aware that investing on ICO today wont give you huge profit just after the launch of the token and after hitting the exchange, give at least 6 - 8 moths for the token price to recover.

Take advantage of the lower price of tokens to gather up more and you'll gain more profit when the token price reach the ICO price.
