I think Botswana is just trying their best to maintain a fraud free atmosphere in the country but if they think crypto poses a threat to their financial security then they've made a huge mistake.
Lets take a look at El Salvador they embraced bitcoin and even made it a legal tender,that is it can be used for payments in exchange of goods and services and this has brought the country to a very far distance bringing about economic development and financial development in the country.
The central bank should think carefully before taking actions because they claim that crypto is being used for anonymous transactions contributing to money laundering forgetting that these transactions can be traced.
Moreover,paper money has contributed greatly to money laundering because the exchange can't be traced enabling the thiefs loot as much as they can and get away with it.
