According to CoinMeta, Bitcoin rose by about 22% during the week of the breakthrough, but analysts say its sustainability will depend on whether ETF capital inflows and spot demand can replace the initial macroeconomic drivers. The U.S. Treasury Department's decision to expand the repurchase scale of long-term government bonds led to a decline in long-term bond yields and a weakening of the dollar, which in turn drove up Bitcoin prices. Analysts pointed out that although Bitcoin's performance was consistent with other markets, its first phase of rebound had a strong macroeconomic component. U.S. spot Bitcoin ETF attracted approximately $1.92 billion in capital inflows during the week of the breakthrough, the largest weekly inflow in 10 months. At the same time, the surge in prices forced traders holding short positions to exit, resulting in the liquidation of $2.7 billion in short positions. Analysts believe that future demand will require more crypto-specific purchases to sustain the rebound.
