What a currency's DNA actually describes

Every currency in CentDNA carries six numbers: liquidity, stability, global usage, accessibility, FX diversification and regional exposure. None of them is a price, a rate or a forecast. They describe what a currency *is* structurally — how deep its market runs, how far outside its home region it settles, how easily an ordinary holder can obtain it.

The dollar is the clearest illustration. It scores 95 on liquidity, 94 on global usage and 91 on accessibility: the deepest market, the widest reach, the easiest to hold. Then it scores 38 on FX diversification, and that number is doing more work than the other four combined.

Here is why. Diversification is not an absolute property, it is a relationship. A currency diversifies you to the extent that it behaves differently from what you already hold — and the overwhelming majority of people reading this already hold dollars, directly or through everything priced in them. More dollars is not diversification. It is concentration with extra steps.

The yen sits at the other end of that particular axis. It scores lower than the dollar on liquidity, on global usage and on accessibility. Structurally it is a narrower instrument in almost every respect. But its diversification figure is roughly double the dollar's, because it has a long history of moving in the opposite direction under stress. That is the entire argument for holding it, and it is invisible if you only read the first three numbers.

This is why CentDNA scores a profile rather than ranking currencies. There is no best currency on these six axes. There is only a currency that fits what a particular person is trying to do, and the six numbers are how the engine works out which.
