Most of the time there difference of price exists so do you withdraw bitcoins from one exchange and sell at higher rate exchange?
Yes I am using multiple exchange, depending on you in which of them your gonna use, of course you must search it first before you trade in that platform. And I don't see any wrong with it as long as it gives you benefits and profit.
Correct and using multiple exchange site your risk will be lessen and also profit will maximize. I think that is the way of thinking of more traders.
Just be careful on engaging in exchange site because there are many sites are scam specially for newbie they should search first before they act.
That's true, its not because it is an exchange sites it means its a good platform already, Of course its not like that anyway.
But doing trade in multiple exchange is nice idea actually.
