Following the craze that cryptocurrencies has aroused since the beginning of 2021, Central Banks are thinking about creating their own digital currencies. In fear of being abandoned, central banks are focusing on the implementation of their own virtual currency. By the end of 2020, some 86% of central banks had launched work to assess the advantages and disadvantages of a central bank digital currency (CBDC).

On February 24, the Fed, the US central bank, published a document listing the prerequisites for launching a digital version of its own currency.

In January 2021, Europeans began to look at the creation of a "digital euro". "The need for a digital euro is a fundamental issue," said Fabio Panetta, a member of the ECB's Executive Board in an article published by Le Figaro in 2020.
Other initiatives have been undertaken in countries such as Switzerland, the Bahamas, Sweden, Japan, China, to name but a few.
