Of course if you can bring a lot of traffic, referral is a no-brainer but i don't think that it is considered gambling more than in the sense you don't know how many results you will get and when.
Agreed. I probably shouldn't have allowed referral/affiliate work into the final list.. it is *not* gambling/betting as you say. It is business.
I guess it depends how you look at it. The time you spend is valuable and it is a gamble that your time will be worthwhile or not. Not everything should be looked at in terms of money.
Affiliates is not that bad but of course its not about betting anymore, maybe it can just as an other source of income through gambling site. Well, if there's an easiest way to make profit on betting, I think no one is losing now. Technically, this poll can help but we know betting is just a game of luck between the teams so don't depend to anyone.
Having good strategies can just help you on your decision but I think it will not be the easiest way to earn in betting. You can study everything about sports or what, but if that team is not lucky enough to win, you will still lose the money. You can look for some bet that is working with the great teams, its easy to find which is better there.
