Currency covers ways of identifying and representing money, from national units to digital assets. The Indian rupee is a conventional currency, while Ethereum and Shiba Inu's SHIB are associated with cryptocurrency. These belong to different parts of the financial landscape: national currencies are issued under a country's monetary system, whereas cryptocurrencies use digital networks to record and transfer value. Currency symbols and asset names help distinguish them, and the collection also touches on related rate and payment-network topics.
