Switzerland has been manipulating their currency for almost a decade now. The central bank has been consistently selling reserves to keep their currency low.

The USD is the world's reserve currency because we have a balance of being the largest economy with a fair rule of law, lots of real estate, 50 competing states, natural resources, and the manufacturing expertise that means if anything goes super wrong we're the best place to be.

Luxembourg and Switzerland also have a history of being tax havens.
