Reply #17: It's not necessarily "when a lot of people" want a currency

[Art_from_Ark]

but rather when major holders move out of one or more currencies into one or more other currencies. "A lot of people" probably won't have much affect on currency markets if they are just buying foreign money for a trip or dabbling in the currency markets. It's really the big players who decide, the little guy just goes along for the ride.
