The only way I know of that can make money online which is 100% guaranteed is a term known as sports arbitrage.
Now you might be asking yourself what is sports arbitrage. Well let me explain it to you
Sports Arbitrage can be regarded as one of the hottest sources of income on the Internet. Put simply sports arbitrage is the action of betting on both sides of a game at different sports books or otherwise known as bookmakers to guarantee a profit no matter what the outcome of the game is.
By backing all competing sides of a sporting event at different bookmakers using the highest odds available, you can set up a situation where each outcome will result in winnings greater than the total amount risked. This possibility arises from a difference in opinion about the fair odds of the event by bookmakers, and one bookmaker has given the favorite higher than usual odds, while the other bookmakers has given the underdog higher than usual odds. Individually neither bookmaker will make a loss, however if you take the combination of the two or more higher than usual odds, it may be possible to bet on all outcomes so that no matter who wins the sports event, your winnings will cover all bets completely and return a profit.
Over the past few years a convergence of technologies has opened up a market which is far greater than the small local markets. In fact, it is by far the world’s fastest growing market. It’s the sports investment market. There are now thousands of online sports books offering opinions (price information) on hundreds of events daily. Football, tennis, baseball and grid iron the list goes on. A trader is now able to “shop” for prices to ensure the best return possible. But what if you could take that a step further…. What if the element of risk could be removed completely? It’s not an impossibility. Thousands of people all around the world are taking advantage of it right now. These people are called Sports Arbitrage traders or arbitrageurs.
The only drawback with sports arbitrage is that you would need quite a substantial amount of capital to start making some money, although you can begin with a starting capital of only $ 5000. However, if this is not in your budget there is another alternative.
