Cryptocurrency

Cryptography was born out of the need for secure communication. It has evolved in the digital era with elements of mathematical theory and computer science to become a way to secure communications, information and money online. 

A cryptocurrency (or crypto currency) is a digital asset designed to work as a medium of exchange that uses cryptography to secure its transactions, to control the creation of additional units, and to verify the transfer of assets. Cryptocurrencies are classified as a subset of digital currencies and are also classified as a subset of alternative currencies and virtual currencies.

Today cryptocurrencies have become a global phenomenon known to most people. While still somehow geeky and not understood by most people, banks, governments and many companies are aware of its importance.

The first cryptocurrency was bitcoin, which was created in 2009 and is still the best known. There has been a proliferation of cryptocurrencies in the past decade and there are now more than 1,000 available on the internet.
