This is a monthly competition for Predictors. Winners are determined by the highest ROI (Return on Investment) achieved from the Predictions*. You can see your ROI in the Profit tab in your Betwave profile. To participate, publish 5 Predictions. There are no extra requirements or restrictions.

ROI (Return on Investment) is a measure of betting performance. It is calculated by dividing your profit by the total amount wagered and multiplying the result by 100%. For example, if you place bets totaling 1,000 vUSD and earn 150 vUSD in profit, your ROI is 15%. This means that the size of your balance is not what matters most—it's the accuracy of your Predictions

Results are summed up on the last day of each calendar month. Only settled bets are counted — pending bets do not affect the results. Cash prizes are awarded to the 5 Predictors with the highest ROI. The prize pool is distributed as follows.

Participants must follow the service rules and fair play principles. Fraud, multiple accounts, or other violations may lead to account blocking. Blocked users will not be able to continue participating in the competition or receive prizes.

Requirements for Predictions and Fair Play

Only independent predictions count toward the minimum participation requirement.

The following will NOT be counted toward the minimum number of predictions:

  • Posting multiple identical predictions for the same event and outcome.
  • Reposting the same prediction to satisfy the minimum participation requirement.
  • Mass posting of identical or substantially similar predictions.
  • Any actions intended to artificially satisfy the participation requirements or obtain an unfair competitive advantage.

The Organizer reserves the right to treat multiple identical predictions as a single prediction or exclude them from the competition results.

If abuse of the competition mechanics is detected, including spam, automated posting, duplicate predictions, or any other attempt to circumvent the rules, the Organizer reserves the right to disqualify the participant and void their results without awarding prizes.

* Starting June 9, 2026, winners are determined by ROI instead of profit. Top Predictors has been updated to reflect the new rules.
