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? 
I usually invest in new projects between 1 and 2 eth. but for a few months I haven't even bought a token in ico, the reason is because I see it difficult to make a profit from this investment. a lot of ico were successful but were destroyed when their coins entered the market.
but maybe next year I will try to invest again considering that many quality projects are starting ico next year.
