I think perhaps two projects that we're going to connect to the Healthcare System. I don't know what happened with them, but obviously they're dipping into a business that has a high amount of Regulation. Bitcoin is not much popular in healthcare business yet.
Nothing more regulated than financial industry and this we see successful today already. Full decentralized application like Bitcoin cannot be closed down by even US government
look to bitlicense:
https://en.wikipedia.org/wiki/BitLicenseGovernment make very difficult to start company in New York City but does this stop bitcoin companies? You know answer!
Same thing to healthcare. I not afraid of regulation
if application decentralized. Sad to say but I see many centralized healthcare ICOs like Patientory and Bowhead.
Look to
MedCredits (MEDX)...look like they will make 100% decentralized and will not be shut down ever

It's a tough nut to crack, and I would say that any project that even got to the first level of approval through the healthcare industry would not become a live functioning project, for at least a couple years until all of the regulation and systemizing was worked out.
