AIDOC is also a medical blockchain but is not included in you list, there are too many projects in this field, hard to identify which one is better.
Yes, I know even peeratlas on NEO blockchain but he does not either. There, they create a medical encyclopedia on blockchain
By the way, I noticed that all projects on blockchain neo are successful. It is not ruled out that neo will shortly replace ethereum
I agree it is not out of the realm of possibility, but I don't think it will be for some time given the amount of ERC20 tokens out there.
I have invested in Medibloc and plan on also investing in Medicalchain. They both offer the same thing, but go at it in different manners. I will see which one comes out on top while likely making a mint on both investments.
