Hi Giulia Paris Thanks for reading. it differs from country to country. The difference in Estonia’s case is that they leapfrogged to digital when they were building the country. For many other countries, it would mean destroying some of the existing infrastructure and then creating a new one. That’s the key reason. However, for a country like India, it has to first provide basic electricity to its villages before it can even provide internet.
The cons of a completely digital economy is that you need strong infrastructure, IT security and backup. But, if you use the Blockchain, a backup is stored on every node on the blockchain
