Arbitrage is not what i can recommend for any gambler to use, because it is not acceptable by so many gambling platforms, knowing this is not enough reason to why we must use such, after all, if we are to look into the statistics of gamblers available all over the world, we are going to discover that most gamblers don't use such and some are not even aware of the same strategy ever existed, because it goes along with violation of the casino terms.
If you don't want to have problems with the bookies, better not to do this practice. Because some bookies are really aware of such strategy and they are not accepting such technique. But if you will do such, make sure you have done your homework and verify the rules of the bookie about this strategy. Otherwise, you are just looking for a headache instead of enjoying your bets.
I understand some bettors would want to take advantage especially if he knows he can get some profits for doing this, however, think of the repercussions after you do such act. You may regret it so better not do it in the first place.
