>A novel point they make is that some group (probably the creators of Bitcoin) control 25% of the money supply. I have not read the paper yet so cannot comment but I was under the impression 95% of Satoshi's coins have never moved since being mined.

From Table 7 on page 11 of the linked paper:

Entity ID | Accumulated Incoming BTC's | Number of Transactions

A | 2,886,650 | 246,012

B | 2,206,170 | 477,526 //Mt. Gox

Since there were 9 million in the address graph, I assume that the 25% remark refers to unidentified Entity A in this table. However, I did not see any claim in the paper that there was evidence that this unnamed entity was trying to hide this accumulation.

Does anyone know why this claim was made in the article?

Yup, because I misread the paper :-/ I thought it also stated that entity A had done large amounts of churning, which it hasn't. I'll fix that, thankyou...
