The price is based on supply and demand. We had this case with India and China too before they close their exchanges. If for example India had a high demand for bitcoin then you will see a 5-10% higher price compared to International price in the other exchanges. It's totally normal, If you could manage to register there and somehow sell your coins then you could actually make this profitable for you.
I have known a person whos making profit from this strategy before,but today it wasn't available since this two countries closed their exchanges already and no one can register again,bad for me because the moment I supposed to enter is that same time closure happens
