If he wins the Nobel prize in economics, he would be in the same club as Paul Krugman.

If you expand to the grand Nobel prize club of all different categories, you get an even worse list:
Yasser Arafat
Barack Obama
Al Gore
European Union

Obviously the Nobel prize has lost all its credibility.

But Milton Friedman won the economics prize in 1976 so giving it to Satoshi could be move to save the destroyed brand of the Nobel prizes.
