My question is why is the rate higher on one exchange than on another?
When it comes to price then it would really be that different on which it would be considering about the activity in between sellers and buyers on that particular platform on which this is the reason on why those numbers would be different but we do know that numbers couldnt really be just that too far off when it comes to that because it would really be that a arbitrage opportunity with those traders who would really be able to snipe out with those price differences on which it would really be just that right that you should really that know on what to do or just common sense but platform wouldnt really be allowing for it to last because arbitrage could really happen.This is why its better not to bother yourself with this.
Some points to remember at least- a bit off topic.
1. Dont make exchange as your main wallet of your assets, its not something a wallet that you could possess its private keys.
