Unless your a professional match-fixer, there are just two ways you can bet without losing money:
Bet without losing by matched betting
Matched betting allows you to profit from the new customer offers and bonuses offered by bookmakers. By creating accounts with lots of bookmakers it's possible to earn hundreds, sometimes thousands, of pounds of risk-free profit.
Bet without losing by arbitrage betting
Arbitrage betting is when you bet on all the outcomes of a betting market in order to make a profit regardless of the result.
Don't be fooled by anyone into thinking that there's such a thing as a guaranteed bet. Many amateur bettors make the mistake of assuming that heavy favourites are guaranteed to win – they are not. There is always the possibility to lose.
