DeriW, a decentralized perpetual derivatives platform incubated by CoinW, has launched the "Edge Hour" limited-time trading challenge with a prize pool of up to 1 million dollars. Participants can join the challenge lasting 1 to 8 hours for just 5 dollars and use a standard virtual account of 10,000 dollars. If participants can achieve profit targets without exceeding drawdown limits, they can receive rewards of 2 to 10 times their entry fee. The challenge is based on DeriW's proprietary Layer 3 blockchain, aimed at making skill-based competitive trading more convenient and efficient.
