Event contracts have no special technology, especially not within 10 minutes. Those who tell you they have a high winning rate just want to exploit you. No matter where you go, they will dare to call it because it's not their money. If they make a profit, it's amazing, and if they lose, it's just a bad market. No worries, there's always another chance! If you're playing event contracts just to make quick money, it's simply gambling. At every point in time and price, there are both losses and gains. Since it's gambling, don't give those so-called experts a cut. You already lose 20% of your profits, and then you have to share half with them. If you lose, you bear the entire loss. What do you gain from this?
