There's no exact answer to this question because it varies from tipster to tipster. Each tipster has his own strategy on picking tips. Some tipsters like to risk more by givings big odds to increase the earnings, but will have a low win rate and the others will prefer to risk less by giving small odds, but keep the winning rate as high as possible.
What we can guarantee is that at the moment the tipster send his tip to you, the minimum odd of that particular tip will be 1.40. We don't allow tipsters to give tips that are below this odd.
