i'm just wondering how does it happen?
i know some of the exchange are just 10 usd lower than others but im wondering why all of them increases accordingly?
I mean if the price somewhere was wildly different don't you think someone would buy and sell on different exchanges to make up the difference ?
The only difference that ever happens is either short timed or very small to care about because of the transfer fees that keeps the profits lower.
There are hundreds of exchanges out there and I am sure there must be some exchanges that connected in a way that some exists in one country while the other exists in some other country and they are both owned by the same corporation but aside from that all the big ones are located differently and owned by different people and until the acquisitions start in crypto business it will stay that way.
