I believe that the key to a successful campaign is to win the heart of the prospective clients. From the day OWNDATA announced( 01/09/2018) its coming till this day of my reply informative material can now be seen on their website and whitepaper
https://owndata.network/. I respectfully suggest that OWNDATA team promote again to the public and this community making us aware of their platform, roadmap, timeline, etc. When private data is involved most data owner are skeptical about the security and privacy- assurance is needed to convince the public and this community that Data from sellers would be secured from being injected with mailicious content and safe in the storage of OWNDATA wallets towards the buyers/clients and vice versa. As per my evaluation this project has a potential it only needs additional development and good promotion. Thumbs up !
