If its not illegal can you show some proof of where it says its Legal in Pakistan ?
Can you show me some proof where it is called illegal some SRO or some ruling by state bank you can't because there is none.
And for your info urdubit.com the first pak bitcoin exchange is working in Pakistan and FBR has issued them the instructions that you must report your earnings and profits of your customers so that capital gain tax can be recovered from them on their profits.
How FBR can demand tax on something which you say is illegal.so surely it's not illegal in the eyes of FBR.
However There is more clarity required in Pakistan that will it be accepted as a currency or only a commodity.
I think for a long time it will be stated as a commodity only bcz there is capital gain tax on commodity and there is no tax on currency.
