The claim matches the specific figures in “先定10个大目标”巨鲸BTC空单浮亏65万美元,ETH空单浮盈41.3万美元 | PANews. That article says Ai Yi observed a BTC short with an unrealized loss of about $650,000 and an ETH short with an unrealized profit of about $413,000, leaving the combined roughly $173 million bearish portfolio down about $237,000 overall. This directly supports the statement that the BTC short was losing, the ETH short remained profitable, and the combined position was slightly underwater. The linked original X post from Ai Yi is present as the source URL in the PANews page, but because direct fetching of that X post failed and independent corroboration search was weak, confidence is medium rather than high.
