There are few factors which you should consider before investing in an ICO like:
Motive of the ico: Why are they doing this? If its simply to provide a return on an investment, then buyer beware.
Experience of the Team: What has the team executed on in the past, together? It should first and foremost be technology related.
Capital Structure of money: How much crypto are they offering to the public? Gauging demand for a crypto is key
Raising the adequate amount money during their ICO: This connects directly to the point above. If they raise too much money during the ICO, theyre going to have to clear loads of flippers. These flippers are those that purchase tokens during the ICO and as soon as the team lists the token on the first exchange.
