I have seen many times that in local market BTC price are quite change from international market. Once the price of BTC in Indian market (Zebpay)used to be 2-3 lacks more than the price in bitfinnix. But todayBTC price in Indian price is 1 lack less than the price in bitfinnix , which is big ammount in terms of percentage.
The exchange always difference about price. A lot of people will use the difference between the international market to earn a certain amount of money.
They buy on this floor, sell on the other floor.
