We have different thoughts about this. If i got well what you mean, i can tell you that going against somebody that hits 60%+ of his bets at odds 1.75+ is not profitable in long term, so why should i care if i have 10000 people betting against me? I don't "sell" picks to make people betting against me and getting better odds. I'm experienced enough to know when to bet on a match to get good odds.
Betting is easier than it seems, because the 90% of the people put their money in "standard ways" and bookies know this. You just have to be patient and smart to make money in long term. The problem is to be always patient and smart even when things seem to go against you.
So you are saying that you are not interested in wagering that you can do exactly what you said you've been doing for the last 5 years? Once again, this is very much in line with people who make claims that they cannot back up.
