The market is of course very unstable and it is difficult to invest and make a profit ! But there are excellent projects that are kept and it's nice to invest in them !
i think there are too many ICOs nowadays and very hard to invest in a really good ICO, moreover the market is very unstable so investing in ICOs now wont be a good idea, however, there are many ICOs using delaying their ICOs ending day to get more investment, we may have profit if we invest as long as we dare to acept the risk to loss our money.
