The Federal Reserve signals again. What does the wave of operations at the end of December—adding $16 billion in liquidity—mean for the market? Some early participants have already entered the previous trend, but the current situation warrants consideration. Loose monetary policy often boosts risk assets, and the cryptocurrency market has always been sensitive to this. Mainstream coins like Ethereum, Bitcoin, and Zcash tend to perform well in a liquidity-rich environment. The question is: will this round of market movement arrive sooner than expected? Or should investors continue to wait and see for clearer signals? Market participants now need to weigh the balance between risk and opportunity.
