The term "gold bug" is often used to describe someone who is obsessed with gold as an investment or a store of value. However, there are other terms that can be used to refer to such a person. For instance, they may be called a bullionist, which refers to someone who advocates for the use of metallic currencies like gold and silver. Alternatively, they may be referred to as a gold enthusiast or a precious metal aficionado. Collectively, these terms capture the idea of someone who has a particular affinity for gold and sees it as an important part of their financial portfolio.
