Yes i also think the whitepaper is worth the reading. Its a bit hard to understand in some part, a little technical, but its important to understand all the possibility of a project I think. Its not needed to read all but at least some part.
I don't read whitepaper, I'm only a trader who speculates on community activity. Also hearing that ehealth has 200 plus pages . I think someday I hope I find time to read it
