Reserve Bank governor Shaktikanta Das on Friday reiterated his call for an outright ban on cryptocurrencies, saying these are “nothing but gambling” and their perceived “value is nothing but make-believe.'' To further its opposition to such currencies and also to take a lead over other central banks, the RBI recently launched its own digital currency (central bank digital currency), in the form of e–rupee on a pilot mode, first for the wholesale in late last October and a month later for retail customers.
