According to EmberCN, a major Bitcoin whale has aggressively increased their 20x leveraged long position to $405 million by transferring an additional 7.505 million USDT from Bybit as margin, signaling significant bullish sentiment and substantial risk exposure in the current BTC derivatives market. This move mirrors strategies used by well-known traders such as James, though with slightly lower leverage and more measured execution. Traders should closely monitor BTC price volatility and funding rates, as such large leveraged positions can amplify both upside momentum and potential liquidation risks, directly impacting short-term market dynamics and liquidity (source: EmberCN via Twitter, June 11, 2025).
