Cryptocurrencies like Bitcoin and Ethereum are not directly or formally linked to gold. Cryptocurrencies are based on decentralized technology and blockchain, while gold is a precious metal that is traditionally associated with monetary value and government reserves. However, there are similarities in the way both are viewed as inflation hedges or value preservers, especially in times of economic crisis.
However, some cryptocurrency projects are trying to offer gold-backed cryptocurrencies, where the value of the currency is directly linked to the price of gold, such as Tether Gold (XAUT) and Paxos Gold (PAXG). These cryptocurrencies represent digital assets backed by reserves of real gold, giving them a value tied to the precious metal.
In general, there is no regulatory or economic relationship between cryptocurrencies and gold, but rather each depends on different economic and market factors
