Of course, blockchainchain can be used in Healthcare. I've even seen several ICOs from this industry. I think such ICO will continue to appear. I participated in ICO WELL. WELL Token already received.
An ICO in the healthcare sector makes no sense to me. If there
was a really good project, they would simply approach a hospital or insurance company who, upon seeing how good this project is and how much money it could save them, would fund it. Why would they need a tradable token to put patient records on a blockchain, unless it's just to make them a quick buck before they disappear.
While I do agree with what you are saying, it is not reliable to assume corporations will instantly pick up blockchain just because it will save them money on paper.
It would be a great incentive though for blockchain to not only protect sensitive data, but to save the corporation's money.
there is your failing. if you cant get a healthcare provider to use it in the first place then its not a healthcare project. its just a empty ledger
if you dont think a institution will use it to protect data. your project is dead before you started.
