[CryptoQuant: Strategy Establishes USD Reserve Fund to Address Bitcoin Bear Market] CryptoQuant's report states that Strategy has established a USD reserve fund covering 24 months, aiming to address potential long-term corrections or sideways movements in Bitcoin and mitigate the risk of declining acceptance of equity financing in capital markets. CryptoQuant points out that this 'dual reserve model of USD and Bitcoin' can reduce the risk of being forced to sell Bitcoin during market downturns. However, it also signifies a shift in Strategy's approach, moving away from continuously purchasing Bitcoin through stocks and convertible bonds. The report suggests that this shift may weaken demand during Bitcoin bull market cycles, but the USD reserves and hedging capabilities help reduce the risk of sell-offs caused by financial pressure, contributing to market stability in the long term. Strategy's management stated that to protect Bitcoin reserves, the company will adopt more flexible strategies, including cash buffers, hedging, and selective liquidation.
