Really? You want to use other people's money to bet on hockey games after they "trust" you? This is nothing but turning users into loan sharks that will probably never get their money back. "I get information on matches". So you check stats just like anyone betting on sports would, and you want people to trust you based on that? Not going to happen.
Well, there are things the op could do to gain community's trust and become a professional that offers payed tips. I think the best thing to do would be to show records of the last couple of months of predictions and investments, so that people can see how good/bad the person knows the thing as well as whether she/he in in profit overall. If a person is good at this job, I am sure there will be people who are interested in tips. But lol, I am not joining a chat with 6 members!
Op, make a website keep records of your bets and predictions (or post them there if you've been recording them), make a nice list of some general tips, offer some free tips on regular basis and then people might get interested in buying tips from you. Good luck!
