The definition of cashless is a condition in which people transact without using cash, but with electronic money or card payment instruments. A cashless society will definitely happen because its phenomenon is relevant to the rapid development of technology. Although both are technologically similar to e-money, but bitcoin and crypto are decentralized and not de yure recognized in many countries. The laws of a country are the biggest enemy of bitcoin development in the whole world. My optimistic prediction is that the world in the next 1-2 decades will be filled with CBDC as the most relevant form of cryptocurrency and can consolidate the interests of the state and crypto users. Regarding the adoption of bitcoin, a country will never be able to follow the decentralized standardization of bitcoin, even if bitcoin is adopted in a country only as an alternative payment (adding to), not a substitute.

The sovereignty of a country is reflected in the socio-economic conditions, politics and defense and security. For the government, state sovereignty is absolute (fixed price) and the full adoption of bitcoin is contrary to the concept of haste. So that the government version of the cashless society is different from the cashless society which is indinently embodied by the bitcoin community.
