A gambling expert brought i and some friends a guaranteed predicted game and asked us to stake a a high amount so that we winning could be huge and so we can give him a percentage of the money at winning.

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?
