On May 13, Bitcoin experienced a sharp decline driven by concentrated selling from large holders, known as whales. Addresses holding between 1,000 and 10,000 BTC decreased their positions by approximately 7,650 Bitcoin, valued at $615.8 million at an average price of $80,500. This sell-off coincided with Bitcoin's price dropping from $81,267 to $78,806 between 12:00 and 17:00 UTC.
Futures Market Intensifies
During the same period, activity in the futures market escalated sharply. Open Interest surged by $589 million, indicating a significant influx of new leverage. Despite a subsequent attempt by futures traders to capture a rebound, Bitcoin only partially recovered, moving from $78,793 to $79,609 by 22:00 UTC. The overall dynamics reflected aggressive whale selling that dwarfed the gradual accumulation by smaller holders, resulting in a net positive balance of just 816 BTC — insufficient to reverse the downtrend.
Accumulation vs. Dumping
On-chain data shows that small-scale holders continued buying during the drop, but whale sell orders overwhelmed their modest purchases. The net balance of only +816 BTC highlights a liquidity vacuum and weak buying power. Analysts warn that similar concentrated sell-offs often trigger short-term sentiment deterioration, especially amid high futures leverage, potentially leading to a cascade of liquidations.
Additional market signals reinforce caution: Wintermute previously warned that the recent rally was driven by futures rather than spot demand, and later data on May 25 showed whales adding a $74 million short position on Hyperliquid. These factors collectively suggest heightened near-term volatility for Bitcoin, urging investors to monitor leverage levels and whale movements closely.
