According to Santiment, Bitcoin's whale wallets holding 10 or more BTC have increased by 231 in the past 10 days, while smaller wallets holding between 0.001 and 10 BTC have decreased by 37,465 during the same period (source: Santiment Twitter, June 19, 2025). This divergent movement suggests that large holders are accumulating while retail participation is declining, a dynamic that often precedes significant price volatility. Traders should monitor this shift closely as it may indicate potential for sharp moves in BTC price, especially as Bitcoin's market value remains just above $104,300. Such accumulation by whales has historically signaled bullish sentiment or preparation for major market events, making this data critical for short-term and swing trading strategies.
