If you invest in cryptocurrency then you must be prepared for the risk (the price go down), especially if you invest in ICO, because for now there are only a few ICO is successful and the price can immediately increase very high, so instead of investing in ICO then you better invest in cryptocurrency that is in the top 100 on coinmarketcap, because the price will definitely increase and of course the risk is less than you invest in ICO, so you will definitely make a profit.
