David Chaum made a significant contribution to cryptography and thus to the emergence of bitcoin. However, this guy already tried doing business before and failed even though he had pretty interesting and high quality tech behind it:
Chaum's DigiCash project came "within close range of achieving a global level of success." However, it ultimately failed to grow its user base to a sufficient size to support its operations. It may have been a combination of infighting among DigiCash developers and team members and a lack of adoption around the world that ultimately led to the downfall of the system
How can we he sure that this time he'll find enough funding and support, will secure strong partnerships and not fight over development matters with other people?
This project does not have enough supporters to become the next big thing yet.
