A cashless society is a controlled society. I think your country is used as a preliminary test for the coming global changes. I'm a huge BTC fan but going cashless is just another step to total government control. Of course they will say it's all for your own good, money carry bacteria and viruses 
In my opinion, the free circulation of fiat currency in cash is very important for bitcoin holders. If bitcoin is not legal tender in the country, then the question arises - how to exchange bitcoin for fiat money?
One of the most popular options is the direct exchange of cryptocurrency for cash fiat currency. However, how to carry out this exchange, in a situation where the circulation of cash currency in the country is limited?
Also a popular exchange option is one in which the client transfers bitcoins to the exchange office, and the exchange office deposits cash into the client's personal bank account (via an ATM).
However, this also requires the free circulation of currency in the country.
