If the icos are valid, and based on real projects, that's very good I think. That means , we have opportunities to take part on one or all of those projects.
The current issue is, most of icos are fake projects, just want to stealth investors fund.
We know, It is very easy to create cryptocurrency token.
Then the fraudsters make a nice website, and put a little sweet promise there. Then, they sell those nonsense.
That is the issue. We must be careful. Never invest on any fake projects
