Legendary entrepreneur and Twitter founder Jack Dorsey is back on the topic of Bitcoin, but instead of talking abstractly about the future of the internet, he makes a very practical claim: “Bitcoin is money,” and later added, “Bitcoin is not a cryptocurrency.”
Interestingly, this is the same idea that is also actively promoted by Adam Back, who is mentioned in the Bitcoin white paper.
Dorsey has long argued that Bitcoin should function as an everyday currency, not an asset for gambling or speculation. He argues that frictions created by regulators and payment rails have distorted Satoshi's original design, and advocates tax exemption for small-value payments.
Bitcoin is not a cryptocurrency

His ecosystem of Square, Cash App, and Lightning is presented as an infrastructure layer on which it can be extended. Feedback from small businesses shows that the message isn't getting through completely.
As he declares Bitcoin is money, sellers are running a zero-fee trial at the farmer market through Square. Dorsey expects these fees to be completely eliminated by 2026, turning BTC payments into a direct peer-to-peer flow. For merchants competing for Mastercard and Visa margins measured in basis points, switching to Bitcoin could be life-changing.
Can Jack Dorsey become Satoshi Nakamoto?
Meanwhile, the internet is reviving an old theory that Dorsey himself is Satoshi Nakamoto.
Once again, proponents of this myth point to a crypto memo published by the entrepreneur in 2003, overlapping timing in early Bitcoin files, an old Twitter profile that included the word “sailor,” the code included a nautical proverb, and even traces of Satoshi's IRC login associated with California, where Dorsey lived.
Some highlight that several important Bitcoin events coincide with dates related to Dorsey or his family. Despite not buying into such speculation, Dorsey continues to support Bitcoin as if it were the very definition of money rather than an investment class.
