but the price of bitcoin has raised coordinately in the Indian exchanges up to 800 USD for 1 BTC which is very frustrating for the buyers
Why is it frustrating for them? Because they have to pay a massive premium over the USD based market price? If that's what you mean, then I can understand that, but it just shows that the demand far exceeds the actual supply on Indian exchanges. When that is the case, and by doing some quick research, it also shows that this is the case, then people are willing to pay more just to get themselves some coins. This will change when people will use this premium as a motivation to withdraw some coins from western exchanges, and sell them at Indian exchanges.
i mean it is good to see that the demand exceeds the supply on theses exchanges but at the same time for someone who is willing to buy 1 bitcoin he is obliged to purchase it with 100 USD difference from the average price in the other exchanges
