That's a joke dude, some trusted ico can still run their icos even the market are in the bearish momentum. That depends on how good the developer is. So many icos have hold their project caused by they have no enough skill to develop the product. Even if they have been doing it and as the result they are still become a scam project right now. There is not guarantee if hold the project means such project will deliver a fully working product. That's just a trick for them because they didn't wanna sell their native coins at the bottom.
don't generalize everything mate because not all are the same,it seems that you are once a victim?thats why pure bitterness is what you have about ICO mate? 
yeah tons of them are scammers and there is no doubt about that but always remember that there are some good one that has no enough Budget so they are still seeking for investors and development to attract investors.
and remember that we have seen some of this,and Bear is the root of most reasons so just let them do the things and wait for the market to help them boost their project.
