A study of digital currency cryptography for business marketing and finance security

A medium of exchange is an intermediary used in trade or business to avoid the inconveniences of a pure barter system. While many things could be used as a medium of exchange in an economy, fiat money including currency bills and coins is the most common and generally accepted as a unit of account which is deemed to represent a standard and store of value. In engaging in e-commerce, people may opt to send money through money remittance agents or through banks for a fee. The Age of the Internet has finally brought upon us a new phenomenon known as digital currency cryptography. No intermediaries. No service charges. No legal fees. No delays. With ease, people of any country can be able to send, receive and store value on their digital wallets.
