Thank you for engaging my post. Yes, there have been some setbacks why Blockchain has not seen mass adoption in health sector. Part of the reasons is what I have discussed with @eliany. But with time, I believe health sector will also use this technology.

You know, research hasn't stopped. When Bitcoin was created, there was no much use cases of the Blockchain and cryptocurrency, but as time went by, many projects were being developed and we can see how it impacted so many aspect.

Thank you once again for visiting my post.

Kind regards!
