Bitcoin is not a commodity, Bitcoin is not a security, Bitcoin is a currency.

It seems ChatGPT would also agree.

"Bitcoin is often referred to as a digital currency because it shares some characteristics of traditional currencies such as the US dollar, the euro, or the Japanese yen. However, Bitcoin is not backed by a government or a physical commodity like gold or silver, which are typically used to support traditional currencies.

Instead, Bitcoin is a decentralized digital asset that is based on a complex network of computers and algorithms. It operates on a blockchain technology that enables secure and transparent transactions without the need for a central authority to oversee them.

Like traditional currencies, Bitcoin can be used to purchase goods and services, can be traded on exchanges, and can be used as a store of value. It can also be converted into other currencies or used as a hedge against inflation."
