Shared a short BNB strategy in the live stream, opened short at 801, then set the stop loss at 810. Later when it was at 799, I also encouraged the brothers to chase, with the stop loss also set at 810. This has a high cost-performance ratio. If this trade doesn't break the new high, we can at least aim for double the profit. Tomorrow we will continue the live stream and strategize for altcoins and mainstream contracts, as well as event contracts.
