This particular version is probably more realistic and reflective of current status for gold which is that is considered less tradable then FIAT or even Treasury debt I think. Traditionally gold should be at the base here, when all other prices become unstable the gold would stay most immune to any scare or disruption in the economy. The reason I'll always disagree gold is similar to BTC is that BTC is far more reliant on trade done, it requires that circulation to a greater extent and so I think its further up in the triangle in terms of risk and expansion, etc.
On the plus side that means BTC is very likely to gain value much quicker then gold ever will so long as it remains valid and useful.
