Even when one paid for predictions (something I myself will never do, or likely never do), I believe such person still have the right to reject and not put money on a pick given to him or her, most especially when he or she thinks that such pick will only lead him to wasting his or her money.
And beside that, I will always advice gamblers to strive to become professionals on their own if gambling is their purpose in this life, one doesnt have to depend on other people, it's like some one who wants to be great in life, but don't want to go to school, doesn't want to learn a skill, doesn't want to do anything but just sit, eat, sleep, bath and repeat, where or how will the greatest come?.
Those who wanna make good money from sports betting to strive to not have to pay anybody for picks, but that other people will have to turn to them for game picks instead.
The trick here is that the person who paid, even a little, feels responsible for this payment, so he must use it. I have noticed this in many areas of life, if you offer something for free to a person, he will not take it even though he will refuse it altogether. But if we offer it to him at an expensive price, he will think that he would not be able to own this thing. This is a rather strange paradox. I also remembered an example about learning a foreign language that people want to learn. There is a lot of accessible and free information on the Internet for studying it, but everyone prefers to hire a teacher for money who will force them to teach. It’s the same here, so I think the one who bought it won’t refuse the paid forecast, because he paid for it with his own money...lol
