@op , no theres no easy profitable strategy
I agree!
...all of them are the same . you can loose or win depending on how lucky you are
I don't agree! There are many sports bettors who profit year after year. They are not lucky, they are smart. They are good at evaluating sports events and good at money management. It is hard work.
Sometimes i don't believe in luck especially if you know the truth behind all of this continuous winning because sometimes you have to think out of the box. It is either they were so smart, lucky or manipulating the outcome. Rich people could do that easily for the sake of profit don't they? Though i must agree with you too that money management is the key too for a successful strategy.
