Any invest in ICO take risk, especially if this doesn´t supported or not have time at the market. I meet people who invested more than 5 BTC in new ICO project and loss their investments, I know is a difficult to talk about it, because it´s about our own investment. This day i look for good new ICOs projects (previous analysis of each one) and decided to invest in these, I would like to have a reference about how much money normally your invest in a new project? 
we know that ICO is an investment with a high level of risk and take many time to get profit, so my advice is do not invest all of the money you have maybe only 30-40%. this is to ensure if in the future the ICO can not generate profits you will not be stressed because of thinking about bill fees
