Each market platform has its own price, we match buyers and sellers. The price of a crypto is in fact the price of the last sale that took place on the platform.
We have no control over what price our customers will want to buy or sell at. As soon as a seller and a buyer meet at the same price, the exchange takes place. This is why there are price differences between the platforms.
You can see the buy orders (in green) and sell orders (in red). The best buy and sell price is always at the top of the list.
