Cryptocurrencies are a current topic among financial institutions, but also among individuals looking for easy money and earnings. There are more and more people who believe in their potential, not only as a means of investment but as a driver of change and a new world revolution. The relationship between cryptocurrencies and traditional currencies is an area that still needs to be explored by the academic community, but there are certainly significant differences between the two systems. Innovative cryptocurrency technologies have enabled individuals around the world to store and transfer monetary units without the need for a central authority. Cryptocurrencies can bring change to the world of finance and many other sectors, and it is up to us to decide how we will deal with them, whether we will provide an opportunity for innovation or continue to rely on parasitic third-party intermediaries.
