For millennia gold has been used as money, a store of value. However gold is a better money then a currency because it better keeps its purchase power with time. In fact if 50 years ago you could completely dress yourself with 100 grams of gold then today you still dress yourself with 100 grams of gold which is not the case with any currency. Effectively if 50 years ago you could dress yourself with 50$ today it is not enough because on inflation
It is a very safe way to store your money, because gold doesn’t run the risk of inflation and you can also get profits when gold grows up.
