I am having a lot of vouches on another forums. I can always verify my tips are real and I can always give a vouch memberships to trusted users
I don't really think that would cut it here. Many scammers have tried scamming people here as tipsters which is why I mentioned that your previous experience won't matter much unless you are a really popular tipster on popular forums like OLBG etc.
Taking tipster bets would not be a good idea. If bookies discover this, they are allowed to void your bets and then you can say goodbye to your strategy.
What are you talking about? How would bookies ever know that you used tips from tipsters? Tips from legit tipsters help a lot in the long run.
