The debate about digital disruption in financial services has escalated since Satoshi Nakamoto created Bitcoin back in 2008. The use of cash is plummeting in many developed countries. In the UK, it has declined some 15% over the last few years, and 35% only in 2020, since the trend has been accelerated by the pandemic. BigTechs such as Facebook have announced the launching of their own digital currency, storming into the payments space. Central and commercial banks perceive this move as a real threat, so they have reacted quickly. According to the Bank for International Settlements (BIS), the advantages and disadvantages of Central Bank Digital Currency (CBDC) were being researched by 86% of banking institutions globally.
