Investing now in ICO have a higher risk than before and for me 2018 is the year of scam ICO so if you don't want to get scammed better to stay away for now and if you really want their project just wait for the token to get listed.  You just need to look at the ICOs carefully before you join in their ICOs. You should have a criteria in joining the ICOs because if you do not know how to look for the good one, even if the ICO is done and not yet giving their coin it is a scam. So be carefully in joining the ICOs.  I think the ICO project will be great again.
