Bitcoin is neither legal nor illegal in Pakistan.In Asian countries,bitcoin is illegal in China.Bitcoin is neutral in India and illegal in Bangladesh.If you are from Pakistan,you can inverse in bitcoin and cryptocurrency.You no need to worry,since bitcoin is not illegal in Pakistan.May be in future,pakistan government will take some decision about cryptocurrency.
Maybe we can consider them in the gray area but it doesn't look good for Pakistan crypto enthusiast because similar to India, the Pakistan Central Bank has issue a memorandum regarding a ban on dealings with cryptocurrencies. And even their local trading exchanges
Urdubit, have close already. So that prohibition is very quick, so the status of bitcoin and crypto is in limbo but it really does have a bleak future in Pakistan.
