"He who does not move does not feel his chains." Rosa Luxembourg’s phrase resonates strangely in the digital age. Digital currency today reveals invisible chains that many still do not perceive.

This tension reshapes our relationship to power, trust, and individual autonomy. The central question is no longer just about technology, but about what we accept to reveal in order to exist. This text explores the existential battle of monetary privacy: protecting human dignity when everything becomes traceable.
