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 seems that it does not just happen in your country in india. likealy asian market such Indonesia, china, korea also have a price that is quite different from the market price that should be. a definite possibility is the presence of certain parties who lead the market so that the original price is different from the global exchange. they take the opportunity from a global purchase with fiat because the fee will definitely make the user think twice in arbitrage.
