Is adage that money has no color is now obsolete?

The currencies gathered these personalities over the last 2,000 years since the first official use of paper money in China. Money was created as a medium of exchange since barter system could not satiate the needs of human beings and since then the medium of exchange that was created to buy-sell assets itself became an asset and people are now buying and selling currencies to make money out of it. This currency trading and speculation gave rise to the currency as a different asset class which was not the case thousands of years ago. It is through the evolution of world financial exchange system that trading in currencies and making money from thereon evolved, which eventually gave character and personality to the currencies. Let us understand this evolution process and where Nepali currency fits in this development.
