Brother, it's time to stop. Your losses from the event contract are the largest I've seen in the square, close to 250,000 RMB. It's already very difficult to break even; I suggest you focus on accumulating your principal. Use 250,000 RMB to trade spot or perpetual contracts; doubling it will allow you to break even. If you must play the event contracts, consider following a strategy to increase your win rate to 65%.
