Its basically the market correcting itself. If the price on one exchange goes up then the overall value goes up. And people usually have funds on both sites, so they usually trade on that, and drive the price up as a result of trading. However there are differences in the prices like Stamp and Finex always have a difference of couple of dollars.
well im just wondering because everytime i try to buy bitcoin, the price is going down
then everytime i sell bitcoin, the price goes up
i don't know if im just unlucky
does anyone here has the same experience as mine?
