Fear - Losing their money - custodian services
Greed - Gambling
All products start with some kind of emotion, the stronger the emotion the more popular
You started LottoShi (a terrible catchy name to be honest) with greed to make a lot of money? That makes me not want to trust your site anymore because you are greedy and can run away with my money anyway.
Though he may have a point now.
A new idea. A new age. That's intelligence. Let's say Bitcoin.
But now you can't really go and introduce new ideas into new ideas, that's just being meta. You can still succeed -- let's call that blockchain marketing or simply marketing, since all business promotion now is really just shaded versions of marketing.
How did cryptokitties make its mark? How did OneCoin or even Bitconnect do? Almost nothing to do with blockchain, almost nothing to do with new ideas, almost nothing to do with intelligence, almost everything to do with emotion. Greed, fear. Maybe there's a point after all.
