Or at least will it die? In all these years, you will find that currency has actually increased in absolute terms, not just in developing and emerging economies where penetration of banking and finance is not yet complete, but also in the developed economies where the penetration of banking and finance has been far larger. Countries are printing more and more of currency.

Some others say, it will be a close call; at least currency will be replaced by Virtual Currency. The quest for anonymous and independent Digital Currency has been in the minds of researchers for quite some time.
