You hit the nail on the head.

"Think of the day when you will be paid by someone to use your medical records for research. That is going to be done in some form of an alt-coin."

Doc.com ($MTC) already has a working app on smartphones that provides free basic medical care to users throughout the world. The service is mostly in Latin America (other than Brazil) right now, but people in Florida and Spain also have access to the service. Doc.com is rolling out its own blockchain later this year. It will be an ethereum fork and anonymized medical information of users of the service will be loaded onto it. The data will be sold to researchers and others for the new Doc coin that will be issued in exchange for the current MTC token, which is an ERC-20 token. Users of the free medical services will be given Doc coins in exchange for their data. The service will have its own crypto ecosystem and the value of the coin will be tied to the data.

Doc.com also offers Doc Emotions in the jurisdictions I mentioned, which gives users access to free basic psychological services. Eventually, Doc.com will roll out Doc Pets, to provide free basic veterinary services to pet owners.

MTC is John McAfee's favorite token.
