But as far as I know, it's impossible to know any data "by owner", we can only do guesstimating on "by address" and then speculate about who owns what.
There will never be a way to properly know any of this, what do we know is that the distribution is super unbalanced, but as time goes by and whales start getting scared, they will sell and those coins will go to more hands.
Just read the first few hundred posts of this thread about the methodology first, and if discussion from that basis is uninteresting, continue in one of the myriad of other threads dedicated to other methodologies!
