Sure, the platform benefits from the differences in buying and selling prices. Don't forget that it doesn't charge fees for transfers. As for the price, you determine it, meaning how much the average cost is to buy each currency and how much profit you make when converting.

Indeed, my brother, you are correct, but there is a point during the conversion which is that Binance gives you a lower price than the spot price when selling and a higher price than the spot price when buying, meaning that the transaction results in a loss due to the price difference.
