It's very funny how it's so scary to even invest in ICOs lately! It's either the whole thing is a joke or developers aren't responsive or just don't have the interest of investors at heart. 
The only thing to do is to wait for them to be listed on some exchanges... More and more often tokens cost less after the end of the ICO. Only in a few rare cases you have a profit buying during ICO
But some ICO tokens turn to shitcoins when the ICO ended. No trading history and no value.
Better to divert our time to trading as there are many coins now are getting ready for the 2018 pump.
Yeah it's risky nowadays to hold alts than to hold bitcoin but this is how the crypto world runs, full of risk and doubts and so the least we can do is to trust and have hope that we can profit.
