Deep Tide TechFlow message. On September 19, Jiang Zhuo’er (Laibit Mining Pool) posted that his short-term predictions are only “fifty-fifty,” and profitability depends on position sizing, trading execution, and coin selection. He gave an example: using the BTC top-touch on September 4, he predicted 4 hours in advance and sold 100% of his position within 1 minute at the highest point for $82,050. During the CPI market move on September 11, although he got the direction wrong, he still recorded a 4.3% overall return thanks to a hedged position structure of "100% ETH spot + 100% BTC equal-quantity short orders." He emphasized that the market is currently in a bull-cycle, so the default state is fully invested in ETH spot; shorting is only to hedge drawdowns and protect spot gains, not to run negative positions. At present, his U-denominated profits have reached 92%, close to doubling.
