If your saying that you are not looking for an overly developed ICO then you are wrong  , to make the ICO as good as it can be , the team had to develop it as far as it can to become successful. For an advice in determining a good ICO , you must first read their whitepaper or go to their website to know more about their project and if a problem occurs tgey respond as soon as possible to solve the problems, they are also easy to interact or communicate with. If they have a SLACK ,that is the best way to communicate with them.
