It is equivalent to winning 28 yuan for 35 yuan, losing 7 yuan each time (calculated at a minimum of 5 standards)

The Binance contract events are so exciting, it's pure gambling, I can't take it anymore. For those without activities, wait until now, it's partially open. Customer service said it will be fully open later. You can open up to 5 unexecuted contract events at a time, with no limit on the number of times. If you lose 10,000 U in a day, you can't play anymore; if you win, there is no limit. The minimum participation amount is 5 U and the maximum is 250 U, with a fee of 20 points. This means that when you win, you get 80% of your capital, and if you lose, your capital goes to zero. I feel that the Martingale method can have some margin for error, but I don't recommend going all in each time; it's easy to get carried away and also easy to lose. The highest point is to find the big pie to make a short position at a high point and a long position at a low point. You have to keep an eye on the market; it's easy to lose if you play in the middle. It's completely based on luck $BTC
