I don't believe there could be a 100% guaranteed game but yet my friends who are eager to make profits in the gambling accepted to play the gamed as instructed and at the end of it, they all loosed the game and at then, the rest of us were happy because we didn't play the game else we would had loosed as others.
I want to ask, do you believe in experts gambling predictions?
Some people claim that they have sure games that they got from insiders. They will ask you for money in exchange for a guaranteed prediction. Luckily some of these games turn out to be correct and they win the game. But in most cases, all these predictions come out negative. Most of these people a just looking for means to exploit people with fake predictions. My conclusion from my observations is that any gambling expert that asks for money to buy predictions might be fake. If they were sure of these games, they would have been very rich and wouldn't need your registration fee. Some of the predictions that play are just based on luck and not skills or expertise. So to answer the question, I think gambling depends more on luck, therefore I should do my analysis and make my predictions. Relying on a so-called expert will make me depend on him and reduce the pleasure I derive from gambling. Anybody that pays to get games from experts, is seeing gambling as a source of income which is not okay.
