Throughout history, large human populations have used different elements as currency, money itself is a recurrent and controversial topic and precisely this statement makes the so-called digital currency the object of criticism, positive and negative but with a significant weight that lies in the uncertainty of whether it is possible to succeed in this business or it is simply another trick of the powerful international platforms.
Digital currencies or cryptocurrencies are a consequence of the digital era and the impetuous development of information and communication technologies (ICT). They probably emerged around 2008, at least the most famous of them, the bitcoin, although there were other experiences before that. Since then, in the last 10 years or so, more than 3,000 have appeared. Global investors are paying more and more attention to it. Large stores, virtual and physical, already accept them as a means of payment.

Google shows more than 11,000,000 references on cryptocurrencies and more than 238,000,000 on blockchain, the main technology that supports them. The vast majority of these publications focus on a technological point of view, however, more economic and financial analysis is needed, since cryptocurrencies are, after all, products with these characteristics.
