Indeed this is an issue that bothers me since some years. We should indeed think about ways to "reanonymize" the cash (even) more.
- petre 8y agoExchange it with third parties the same way we change currency with family members to avoid fees.
- wolfgke 8y agoI already thought about that idea. I am not sure, though, whether this "randomizes" the banknotes sufficiently to avoid more advanced tracking algorithms, since the banknotes stay in your social circle.
