The concept of money has been in circulation for almost 3,000 years, from its origins of bartering beans for cattle to modern day transactions via bitcoin. From the outset, money has worked on one simple principle. Trust. The trust that the value of the ‘money’ you receive and exchange retains and holds equal value elsewhere. This has evolved from trusting the number of cocoa beans required to exchange for a piece of beef to trusting the £5 note given to you by the supermarket holds the same value in the pizza takeaway around the corner.
