I suggest you checkout ICObench. It's a site that collates reviews about ICOs and rates them too. They're pretty useful.
I also think like you! Trusting the proposals will give you a good base in choosing the ICO for your investment. But there are always hidden risks. In my opinion, in addition to the suggestions, you need to rely on your knowledge, experience to analyze the project thoroughly. This will give you a good decision, the risk in the ICO investment will be reduced.
