No, they won't die, because of the falling market. When the market will turn green everything will recover. Low market volume = low prices = lack of investors. Green market = bull run = higher prices = a lot of investors = ICOs that are reaching hard caps.

This will depends on the developer if they want to take a risk to give the token and list on exchanges immediately or wait until a bullish market. Some project will not mind the market and they will distribute after the crowd sale and get listed on exchange as a result the price hit the bottom and the investors will get angry to the team.
