Bitcoin briefly fell below $73,000 USDT as easing tensions in the Middle East, following a ceasefire memorandum between the U.S. and Iran, triggered a broad market correction. The decline in BTC's 4-hour high indicates a short-term bearish trend, with on-chain dynamics showing intensified long-short activity. Whale trader Loracle's 5x leveraged short position is under pressure, with unrealized losses reaching approximately $29 million. Additionally, the "1011 turnaround whale" increased its ETH short positions by 2,407 ETH, valued at about $4.86 million, raising its total ETH short exposure to $6.54 million.
