just invest in ethereum and forget it in next few years thats all i can say to you.ICOs are too risky if you wanna gamble go ahead invest in ICO it can double triple your money and also you can lose %90 of it in a month.
ICO is too risky for people who don't do a well research before investing. Anyway, I think everything in here is a risk its a matter of believing to something. ICO compared to other strategy is still profitable of course if the project do succeed, the problem is because of too many scam projects outnumbering the good ones. Right now my bet is on OPP and MENLO.
