true, just try to fix a match and then play with the spoils.
No, gambling is an addiction and does not pay, if it was so easy to maintain your discipline punters would make money and not the bookies.
You can be the best tipster in the world, have 10 fantastic calls in a row, just one bad call will ruin everything.
I agree with nastoff here, Tennis betting was profitable till 2009, After that the virus of fixing which how much we try not to discuss has crept in big time in the sport of tennis, There are hardly any matches being played on merit and the worst part is even the top ranked players are involved in this, From the Media to the tournament managements to the tennis association, all are aware of this but none can do much about it as it can't be proved if a player has actually fixed a match (Ex. Davydenko Vs Arugello and others).
Now in this scenario, we the punters, when placing a bet, rely on the form, fitness, surface and stats of the players, The result, the player who can beat the opponent easily goes down to lose, Some punters, do win as well, When they win they get a euphoria in mind which can be described as a kick, wherein the punters feel they are on the top of the world, Then the punters goes on to place bets on the other matches... As said above, matches are decided pre hand, He loses a bet which is certain to come in, There comes the downer in the brain of the punter.
Now the punter feels like pulling his hair out for losing the bet, he places another bet, probably wins on that, again he gets a kick in the mind then he goes to the next bet, plays big, goes on to lose big time, again comes a downer in the mind... In all this process, there are only 3 % of the punters who somehow knows the result before hand make some money, all the others are simply wasting their time, energy, effort and draining their banks....
