Is there an alternative way to attract investors beyond the technical aspects? I would like someone to answer this question and discuss the issue.
Not on current evidence, no.
The "technical aspects" are the only aspects of an altcoin clone that are objectively (or near offer) available to investors for informing their assessessment of the potential ROI.
However, to use the term "investment" in the context of swapping tokens of a clone of Bitcoin for bankable fiat is stretching the semantics of the term well beyond its breaking point. If the reality of the context were to be honestly acknowledged, then a far more accurately descriptive term would be "speculation".
(for Google translate: use your common sense, it's not "investment" but "speculation")
There is no point in trying to discuss
psychological matters (such as "appeal") on bitcointalk but I have rounded up some of my observations in a single post
a different perspective on cryptocurrency.
For background, I'm a cognitive scientist currently engaged in investigating the informational requirements of the typical tasks performed by an online collective intelligence and, for me, the technical aspects are more pertinently addressed elsewhere, including for example the psychology of money and the empirical work (open access) done by
Kathleen Vohs and collaborators, for one:
"No Match for Money: Even in Intimate Relationships and Collectivistic Cultures, Reminders of Money Weaken Sociomoral Responses,"
"Money Cues Increase Agency and Decrease Prosociality Among Children: Early Signs of Market-Mode Behaviors,"
"Money Priming Can Change People’s Thoughts, Feelings, Motivations, and Behaviors: An Update on 10 Years of Experiments," <- that's a
decadeand
Elinor Ostrom for another.
(Coincidentally, this reference
The Future of Management Is Teal turned up on HackerNews a few days ago, if you're interested in Teal in a broader context).
