Simple arbitrage question. I mean every newbie out there asked the same question one day or another. Unfortunately the difference caused by the fact that those exchanges have their own markets, their own people who sell and who buy which means these are different people reacting to market however the difference is there constantly because of the different volumes reacting different.

It is never too much because arbitrage people make sure to take advantage of any big amount and close that gap eventually but for regular people it is just regular buy/sell amounts being different in there for a while and never above the % fee they take.
