According to Crypto Rover on Twitter, significant amounts of Bitcoin (BTC) are currently being withdrawn from centralized exchanges, suggesting large-scale accumulation by whales (source: @rovercrc, May 13, 2025). This pattern of withdrawals is often seen as a bullish signal for traders, indicating strong holding sentiment and potential supply reduction on exchanges. Historically, such trends have preceded upward price movements as market liquidity tightens (source: Glassnode, on-chain data). Traders should closely monitor on-chain BTC outflows and exchange reserves as leading indicators for potential price volatility and spot buying opportunities in the crypto market.
