WHY NOT START A FREE SERVICE 1ST TO GAIN SOME REPUTATION
these are very safe bets i'll give them to only a few people i can give vouch copy to 3 users for a week
I am also agree with the escrow
If you are professional tipster you have to know that there is no thing like 'safe bet' every bet is risky, and you can't win all the time.
If you could win all the time, why bother with selling your tips then? Sooner or later you are gonna lose. And like other said, go to gambling section, start your Thread and offer free tips for a month or so.
If people will know that your prediction are 90% true then you will be able to gain money from it. Nobody is gonna ask you when there is no confirmation of your prediction accuracy.
