New number #事件合约 , fifth day in a row, currently making a profit every day, total profit has reached 11,000 dollars. Many people ask whether event contract doubling is better than regular investment. Personally, I suggest that event doubling is relatively better than regular investment. I have tested it, and if you keep investing regularly, with a win rate of around 60, there is basically no profit. Of course, doubling can bring quick gains but can also lead to quick losses. When accepting profits, one must also accept risks, and doubling is very sensitive to one-sided trends. When encountering a one-sided trend, you can only cut losses and back down.
