Bitcoin Is Kosher Bitcoin serves as a tool to overcome the ethical barriers in lending, aligning with Jewish principles. In this context, “kosher” goes beyond its traditional use for food and denotes an action consistent with Jewish ethics. Bitcoin is kosher because, as disinflationary hard money, it removes the economic incentive to charge interest. A concept so abhorrent that it has become a religious law not to do so. Bitcoin has the properties to serve as a monetary base layer for a financial system consistent with Jewish ethics.
