First of all, a very hyped ICO might be somewhat overpriced to begin with. Second of all I would try to look behind all the hype and focus on the core tech behind the coin/token and also the team behind it.
I also do that when i am investing in an ICO because that is the most important part of investing into ICOs projects. Do some checking first before putting any amount of your hard earned money so you will not experience any huge losses from investing. A good investor is always good in background checking before making a decision regarding in investing.
