Biscoint helps you find the best price to buy and sell Bitcoin in your country's exchanges.
It takes into account the market information supplied by exchanges in real time, the fee rate each one of them charges, and the amount you wish to buy - how much money you want to spend, or how many bitcoins you want to get.
From that Biscoint builds a price ranking - tailored to the amount you supplied.
It also calculates an index called Dollar Bitcoin, which helps you evaluate if Bitcoin in your country is cheap or expensive in comparison with Bitcoin in dollar terms.
