I really would like to know if Vitalik Buterin has invested here in eHealth too

Would be really amazing!
HA! everybody would like that , but don't hold your breath. even if he was, it wouldn't be public.
if we would hear something like that, the whole ann thread would literally explode

Why wouldn't it be public? He already invested in sens, everybody knows he's into healthcare and fighting aging and stuff.
why shouldnt it be public, this would be very good advertisement for ehealth and puhs the price of the token really hard and vitalik would also profit from the rise of the price
