I think the biggest hurdle is the perception that starting a cryptocurrency/blockchain business which becomes quickly profitable/valuable is unfair to others because of the founders stake. When in reality, the founders are the ones taking the biggest risk, developing innovation, and doing the vast majority of the work. We don't see this in other highly-successful traditional businesses as it is done behind the scenes. But with blockchain and cryptocurrencies, it is more transparent, therefore it is open to more criticisms.
