Credit Suisse got it wrong (Score 1)

The premise of the Credit Suisse article is wrong. A bitcoin "address" does not mean a "person". Some addresses are pools held by exchanges or funds for a great many people. (Just like stock held in street name ... so you'd think these wall st guys would get it.) Some individual people have many addresses. So addresses to people is not 1:1. It can be many:1 or 1:many, and you can only learn a limited amount about concentration from the blockchain.
