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? 
Due to the current market situation, it stopped investing at all. Last year, the projects still somehow developed and made efforts to promote their ideas. Now the situation is such that even with the purchase on the pre-sale under -80, investors do not always go even to 0!
