I don't know much about Nepal and I think it would be better if you attached some link that can help us be educated. Nevertheless, I've made my own research and it says that the Nepal Rastra Bank has accepted Bitcoin as ILLEGAL form of financial tender. The article was updated year 2019 and I've no idea of its state in this year 2020. Maybe, just like in India or China, they are used in trading or exchange as what you have said that is from their finance minister. If this is indeed the case, then it is great. If countries such as Nepal that has a strong stand on banning crypto and then accepting it a little while can be a good signal for other countries to follow.
