Dollar bulls may generally hold the view that it is sheer folly to bet in the long term against the U.S. economy, and by extension the U.S. dollar. Dollar bulls might not specifically know which currency the dollar will outperform, or they may take a bullish position against a specific currency. For example, dollar bulls could believe that the greenback will increase in value as long as it remains the world's dominant reserve currency, since it is backed by the economy of the United States and its government. Or a dollar bull could bet that the U.S. dollar (USD) would specifically outperform the euro (EUR).
