Why BTC price is so low at Bittrex. Sometimes I see 400 - 500 $ difference between Bittrex and other exchanges. Arbitrage will be something but BTC is too slow this days that is why they make money on such a price difference.
Going back before seeing on the price of bitcoin on each exchanges does really vary on small spreads but now same as you said their difference is almost $400+ specially on bittrex when I do tried out to check the prices recently on bitcoin to those exchanges.I might think that I can do make money on doing arbitrage trading since spreads or gaps is too decent to make money but I'm not still sure to do such thing.
