Although many people have understood the cryptocurrencies idea and has learnt much about it but I don't think crypto is the only thing that can make the world go digital.
Judging by the development of humanity, our world will not be able to become digital for a very long time. A global catastrophe is enough, and again we will deal only with the vital problems of survival, which has happened more than once. In addition, now the cash of the states, non-cash money and cryptocurrency will continue to develop in parallel and no one will crowd out.
