GP* articles on Financial Cryptography

I am enjoying the series of articles on business growth and fraud at the Financial Cryptography web site.
The overall theme is that, whatever level of technical perfection you achieve in a money-handling system,
things really only get interesting once the business takes off — at which point an equilibrium is reached based both on what you implemented and on how much it’s worth attacking.
The first article started the series a bit slow and abstract; for me, I like details.
The latest installment, the most concrete so far, is a case study regarding e-Gold, with some bonus comments regarding WebMoney. Note that even without technical flaws, your business is still affected by attacks on the whole business ecology (much of it out of your direct control): partners, customers, complementary businesses, reputation mongers.
