Most countries just sit on billions of d ollarspoundseuroswhatever of other countries currency . You can exchange your currency at a fixed rate with the government and they ' ll give you some of that money from that pile . However , the deal is usually crap compared to other banks within the country , as the deal is only there to make that country ' s currency have a minimum to how much it ' s worth in case all the banks exchange rates fall too low . When China devalued their currency , they simply lowered the fixed exchange rate . If any of this is wrong , please correct me as I ' m having a hard time wrapping my head around the concept <| sep |> The one down the hall ? <| sep |> You ' re god damn right <| sep |> She thought I was a pizza crap .
