I don't really think that ICOs who failed their financial goal will necessary fail. The hard cap sometimes is just a security measure for investors, but that does not mean it is their actual funding goal. Actually if they did reach their minimum cap, that may be enough for a good development. Each ICO and company are very different and you should not rely on only one metric. Good investment decisions come from having a good knowledge of the companies / tokens you decide to buy in.
Yep if the team has a good idea of how much is needed they will put that amount on the min cap I guess.
