It's called being an "on risk" currency. Canadian and Aussie dollars are the same. Basically follow the highs and lows of the market indexes.
It's actually considered a useful thing. Holding your assets in an on risk currency whilst earning income in a base currency like Euros or US$ in the bad times.
Imagine how awesome this would be for you if your assets were all bitcoin and every time you got paid in US$ at work, it was converted to bitcoin each time. Your income would be nearly double what it was last year... in the same moment everyone else's buying power has gone down.
