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.
It depends on the supply and demand on each exchange. Different exchanges has different coin prices. Maybe in Zebpay, there are few traders who are buying Bitcoin but has a huge supply compared to other exchange sites. Try to compare the prices with other exchange.
