The vast majority of people who are regularly betting on football will incur a long term loss. That is an undeniable fact. While the masses are placing losing football bets time and time again, there are a select few who are consistently earning a substantial income from profitable football betting.
The vast majority of Betfair users treat the bet exchange as a recreational activity. Consequently they regularly lose money. Pretty much in the same way my grandfather religously did the football pools each week to no avail. It was done in the hope of winning money rather than in expectation. It is not rocket science gentlemen, if the majority are losing money on Betfair then there must surely be a minority making money, right?
