Money is often defined in terms of the three functions or services that it provides. Money serves as a medium of exchange, as a store of value, and as a unit of account. Money's most important function is as a medium of exchange to facilitate transactions. Without money, all transactions would have to be conducted by barter, which involves direct exchange of one good or service for another. In order to be a medium of exchange, money must hold its value over time; that is, it must be a store of value. If money could not be stored for some period of time and still remain valuable in exchange, it would not solve the double coincidence of wants problem and therefore would not be adopted as a medium of exchange. Money also functions as a unit of account, providing a common measure of the value of goods and services being exchanged. At the beginning of the cryptocurrency boom, Bitcoin seemed to be the unquestioned leader. Up until recently, Bitcoin accounted for the vast majority of the industry's market capitalization; then, in a span of just weeks, Ethereum, Ripple, and other currencies rushed to catch up. While Bitcoin is still in the lead, the rapid turnover in the industry has some analysts debating if cryptocurrencies are actually currencies. Some are predicting that even bigger changes could be ahead. Among them? The idea that cryptocurrencies could come to replace money entirely.
