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? 
uncertain, depending on the money I have at the time and the possibility of profit that I can receive (through my own analysis), but for now on average I invest to a new ICO in the amount of $ 1000 - $ 3000, although for this year the profit earned is very small, which is around 10% -20% of the capital that i spend, unlike in 2017 where the profit that I can get is at least 50% of the capital that I spend.
