Several of these ICO's value their tokens at .3-5+ before any work has even started, it's insane. I would say if you can get in a pre-ico with a solid team / idea / product it might be worth it but other than that you may as well invest in an established alt.
the community itself is everything. no team can be successful without an active community that raises demand for the product. that's why projects with an anonymous team can be successful too.
