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
Most ICO are scams.
