I have read at past that India was going to ban crypto and make it illegal to hold bitcoins. It's great if something has changed in a very positive way in India in crypto world because India is a very poor country and I have no idea why the government wanted to lock one great way of earning of money for people, at least they do nothing that may harm someone, so, logically there is no problem.
However, there is always little higher price difference in USD and INR. Even I have observed that for all the coins including bitcoin the price is little higher as compared to USD-INR-Fiat pair.
When crypto is traded into local currencies, there are additional fees of exchange added, i.e. when you convert Bitcoin into INR, at first there is done Bitcoin - USD conversion and then USD - INR convert, that results in more fees.
WazirX is acquired by Binance, right? I remember when their coin reached very high price.
