Hunter Horsley, the co-founder and CEO of cryptocurrency asset management company Bitwise, said that the term "digital gold" limits the coverage of Bitcoin as an investment asset. Although the image of "digital gold" is helpful for Bitcoin, it has many qualities that are superior to gold. It is time to get rid of this concept. Bitcoin has had many visions in history, such as peer-to-peer electronic cash, independent sovereign currency, and cryptocurrency, conveying people's different expectations of Bitcoin.
