Why do you want this info, if I may ask? You know this type of information is very unreliable and constantly changing.. right? If someone
see a list like this on the internet somewhere, where they are dox'ed, they just sweep those coins, push it through a mixer and split it
into smaller cold storage to make it less attractive for hackers.

... The richest Bitcoin users, will not keep all their coins in one address,
because it attracts too much negative attention.

Cause I want to know how exchanges are moving users deposits? It might change I know, but some exchanges are publishing it officially, so why are you suggesting it's a top secret info.
Ah, I missed a crucial part of your question there... sorry. I now realize that you only want the rich list for exchanges. You should add
that to your thread title. At the rate at which these exchanges are being hacked, it might not be a good idea to publish this information
in public, even though most of these coins are stored in cold storage.

If you know how deep their pockets are, you might consider
kidnapping and ransom scenarios.
