The problem with most new ICOs is a lack of a real-world product. They all give you the same blurb about being decentalized and how they are revolutionary and going to change the world, yet they do not have a useful product, and if they do, there's no legitimate business plan on how they will take over the world. Most don't even allocate a proper marketing budget outside of marketing to raise money for the ICO.
Do not let yourself become emotionally attached to any coin you have, or any ICO you are thinking of getting into. I will not write about which recent ICOs I think were not worth it, since I'm sure we can guess as a collective group of smart readers. That being said, if a company adjusts the rules of the ICO abruptly and soon before the ICO, maybe it is a sign to take another look and decide if you still want to buy the coin.
