Speaking from my experience...

At first I thought @Fore_Gate was just another prediction market. But after using it for a few days, I realized that not only prediction is done here, but there is an opportunity to earn extra reward even if it is active.
Now the best thing is Double Reward Campaign.
If you predict regularly, you can unlock weekly bonus. And for those new to join, there is First Bet Protection, so it is very easy to start.
Weekly Reward Tiers:
• 💸 $10 → Deposit $20+ & $500 Trade Volume
• 💸 $20 → Deposit $20+ & $1,000 Trade Volume
• 💸 $50 → Deposit $20+ & $2,500 Trade Volume
• 💸 $100 → Deposit $20+ & $5,000 Trade Volume
• 💸 $200 → Deposit $50+ & $10,000 Trade Volume
I myself am now exploring the World Cup prediction market. If you follow football and like to make predictions, then you can take a look at this campaign.
Sometimes the campaign reward along with the correct prediction makes the experience more worthwhile.
