Matrixport stated in its latest weekly report that as Wall Street fully embraces Bitcoin, Bitcoin ETFs are increasingly influenced by global liquidity, macroeconomic conditions, central bank policies, and institutional capital flows. The strengthening of the US dollar has led to a decline in this liquidity indicator, indicating that the price of Bitcoin may be under downward pressure. Global liquidity reached its peak at the end of December 2024, and the significant strengthening of the US dollar provides a clear explanation for the continued pullback of Bitcoin. Looking ahead, the forward-looking nature of this time series suggests that once this correction ends (which may continue until March or April), Bitcoin may attempt to rebound to its previous highs. Wall Street investors entering the Bitcoin market are divided into two categories. One type is wealth and asset managers, who may represent the wallet group holding 100-1000 bitcoins. This group has become the largest bitcoin holder, surpassing the once dominant whale wallet. The second type of Wall Street investors entering the Bitcoin market are hedge funds, who focus on non directional returns through arbitrage strategies rather than betting on long-term price increases in Bitcoin. When cryptocurrency traders are bullish, they typically use futures positions to push up funding rates, providing hedge funds with arbitrage opportunities. They buy Bitcoin spot or Bitcoin ETF while short selling Bitcoin futures, earning profits through the funding rate difference. These hedge funds hold a total of $10 billion in Bitcoin ETFs, and the total inflow of funds has reached $39 billion, indicating that at least 25% of Bitcoin ETF funds are related to arbitrage trading. According to our calculations, 55% or more of ETF inflows may come from hedge funds focused on arbitrage rather than investors who truly believe in Bitcoin's long-term upward potential. Since the FOMC meeting in December last year, there has been a significant decline in yield opportunities, followed by a decrease in trading volume, so it is not surprising that hedge funds have started to unwind their arbitrage positions. This trend is reflected in the record breaking outflow of funds from Bitcoin ETE, as these funds exit trades that are no longer profitable.
