I’ve been really interested in fungibility lately and it’s importance when it comes to any currency, especially a digital currency. And to me from my limited knowledge of the subject it seems that Monero is far more fungible than even cash is.
Every piece of paper money has a unique serial number and in many cases cash can be “dirty” and associated with crime. Hence the billion dollar money laundering industry.
Monero seems to be one of the only (if not THE only) easily transferable truly fungible means of exchange.
