# Earning Mechanism \*Users can match at least 2 and at most 20 events in one bet. ### Earnings Calculation Earnings are calculated according to the formula given below; $$ BTBEarnings=FanCardRate\*OverallOdds $$ ### Fan Card Rate Calculation $$ FanCardRate= 1+Level\*0.1 $$ > **Case Study:** A user chooses to bet on two different events for two different matches, the odds for these events are respectively 2.25, and 1.8 . The overall odds are calculated as: 2.25 x 1.8 = 4.05 . If the Fan Card Rate is 2.5 , potential earnings are equal to 4.05 x 2.5= 10.125 **BTB**. ### Earning Cap Every user has a daily limit on their BTB earnings. This limit is the "Earning Cap", and it's based on the level of their Fan Cards. Upgrading your Fan Card will increase your daily earning cap. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
