CHAPTER 3
WHAT IS
CRYPTOCURRENCY?
hen most people think of money, they
Wusually imagine coins or paper bills. This
form of money is physical. It exists in the real
world. For example, suppose a woman walks into
a store and wants a bottle of water. She gives
money to the clerk, and the clerk gives her the
drink. That is how transactions have worked for
thousands of years.
People have been using coins since at least
600 BCE.
