I often find price differences at each exchange. I think this is one of the coin exchange strategies to make a profit too. Where can they benefit if they do not take the difference in coin prices? Because I think, just relying on WD's costs won't make them profitable.
It could also be like that because the team from the Bursa side also wants to make a profit.
But maybe it is more appropriate that when cryptocurrency is already on the market it cannot be predicted and the price is always up and down because the difference in the owner of the coin is not centralized.
