This is interesting; in effect understanding this eases some distribution concerns I have. Correct me if I am not understanding this correctly, the Bitcoin economy is in
recession when the Fiat to XBT rate is increasing. IE the result is outflow of XBT - in effect a
trade deficit in XBT (the prevailing activity is speculation, and the effect is new market participants and the Bitcoin converts become euphoric - dollar extraction and saving are the economic activities)
Then as we switch (the crash/ correction we call it) to a trade surplus, increased outflow of XBT relative to Fiat, we enter a boom in the business cycle, the low demand for XBT is actually reflected as a higher demand for Fiat, which in turn is "sometimes" diverted into projects. (The prevailing activity is infrastructure development, and the effect is new market participants and the Bitcoin converts become bearish and worried about exchange rate - "imported resources are invested and shorting XBT are the economic activities)
In traditional forex pricing theory, if country A export goods to country B, country B must first buy country A's currency and then purchase country A's goods. So, a trade_surplus for country A will increase the demand for its currency, thus raise its currency's value and in turn discourage its export, thus reach a balance
But this is just a best guess, the power difference between those two forces could be magnitudes. In fact, the currency itself often becomes some investment target because they carry an interest rate, so the forex exchange rate are largely affected by the interest rate difference between currencies
Bitcoin itself is also an investment vehicle. Unlike other currencies that can give some interest return, holding bitcoin won't give you any return in bitcoin. But it will act as a benchmark for other currency's supply. If other currencies supply increased exponentially while bitcoin's supply is always fixed, just from supply and demand point of view, its forex exchange rate will rise exponentially
It is not bitcoin that worth so much, it is fiat money that worth so little
