I think it would be DOCADEMIC, since it signature campaign is managed by hilariousanco then only good poster are accepted. And I really like DOCADEMIC work model. Its platform is already used in 20 countries. They only sell MTC token to power their business operation and MTC holders can use it to buy products or service in healthcare providers in DOCADEMIC. I hope the ICO success, so many more people can have access to healthcare services.
