Are you guys looking for the best rates in the market when deciding to buy/sell Bitcoin or you're bond with the certain exchanges where you have an account?
If you do mean on buy/sell btc then i do only hang up with a single exchange rather than on multiple ones yet as mentioned earlier if you do pertain with arbitrage then it isnt really worth the time yet
prices on exchange doesnt really differ that much when it comes to gaps/spread between prices.So its not really worth to try or think of. When it comes to best rates then you should not
stress out yourself to this one.
As others have said, arbitraging is really not advisable considering the fees (trading, withdrawal) involved. If you account those fees, you will come up with very minimal profit if not zero. Unless, you find an altcoin other than bitcoin to trade. Because there are some good finds that the price difference are quite big. But you have to be careful as the trading or withdrawal might take too long because for one, there maybe few traders on that market, so you have to wait for considerable of time to sell your coin and once you got it, withdrawal from that exchange is not instant. So it depends on your priorities. But on my end, I don't think it is advisable to waste your time on this if you don't have enough resources.
