Good link - that's the real time stats for the richest in bitcoin.

It's pretty crazy to think that there are 1,000+ addresses that have over 10 million USD worth of bitcoin in them, I'm assuming that they would mostly be cold storage for companies and exchanges.

What would be an interesting stat, would be how many rich addresses are owned by a single person, not a company or an exchange. It would be interesting to see some of that information... Couldn't imagine more than 600 addresses of the 1,300 addresses being owned by a single person.
