For me personally, if they start with high price and unreasonable , I'm better to stay away rather than sorry.
But if you lucky enough, you may earn some profit for investing on random ICO
~Luck 99% , skill 1% , guts ? %
So you can participate in bounty campaigns to make some money with them. If you invest or join in bounty they will you paid the tokens after the token sale alone so working and making the alts would be fine option according to me.
Why i not suggesting the investment on token sale because they may cheat us and ran with the investment you gonna do.
