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.
investing in established alt is casino style gambling the premine that the issuers sell is the systematic loss you win only if others lose good luck with that.
good team good product i can show that, but then there are also compeletely anonymous systems that people like more
