You need to buy those big Christmas socks and store your money in there
edit: and regarding the scamy companys my opinion is that if you could actually prove to the public that it IS posiable to make money from betfair regularly you could see more volume on the markets. Something like poker revolucion 10 years ago when some guy named Moneymaker won a million dollars on a poker tournament. Then maybe banks wont reject you and you wont need to have that awkward feeling when you tell people how you make money. I know from experience at least half of my close friends do not believe me when I try to explain trading or arbitrage betting.
