In my opinion this is not the right time to invest in ico because there are many scam project in forum now.So stay away from investing ico for few months.When the market overcome then invest in good ice.You have to check their website, roadmap, team activity etc before investing in ice.
Investing ICO is not good because we don't know how much % team is serious about the project. So after completion of ICO, once they list in the exchange we can start buying them we might get cheap compared to ICO price.
