#事件合约 To be honest, that event contract can be manipulated, but the cost is very high. There is no such thing on OK, but on Binance, you can easily bet a little on the event contract. As soon as you place an order to go long, Ethereum drops. I quickly opened a contract for 200 Ethereum, and the price stabilized instantly. I made a profit in 10 minutes, but the transaction fees for opening and closing the position lost me even more 😂... As expected, small profits and big losses.
