I see investment as a stable low risk term. I love block chain technology and think that if implimented properly could produce a great efficiency gains and cost reduction. Even with my bias to the technology and my liking of private transactions, all altcoins are illiquid and unstable. They would be better speculation tools, but their lack of liquidity means that when the bubble bursts you could be very rich or very poor.
I like to think that investment as separate from speculation so no I don't currently see any altcoin as an investment opportunity.
Something I admire about recent ICO models is that they are more of a survival of the fittest, since we've dropped from ATH, investors and early backers are backed to a wall, and would only result to DD; thereby investing in only projects that matter. But amidst this structure, HiNounou has refused incentive based token sale event and refuses early adoption bonuses. It's really a good thing to help democratize the token sale, and no single investor will be able to hoard so much tokens only to dump upon listing. More projects should consider removing bonuses if they must sustain their projects long-term.
