The recent week has seen an interesting divergence in the Bitcoin spot ETF market. From January 12 to 16, the market experienced a net inflow of $1.42 billion, with funds continuously pouring in, reflecting investors' ongoing optimism about Bitcoin.

The most prominent performer is BlackRock's IBIT, which saw a net inflow of $1.035 billion in one week, nearly accounting for 70% of the total inflow. This asset management giant's spot ETF products have accumulated a total of $63.44 billion, making it the most popular choice in the market. Fidelity follows closely, with FBTC inflows of $194 million this week, bringing the total to $11.92 billion, showing steady growth.

However, Grayscale's GBTC has recently had a tough time. This week, it experienced outflows of $1.6757 million. Although the weekly figure isn't large, from a historical perspective, GBTC has been continuously net outflowing, totaling $25.41 billion. In comparison, the appeal of new spot ETFs is evidently stronger.

So far, the total assets of Bitcoin spot ETFs have reached $124.56 billion, accounting for 6.53% of the entire Bitcoin market capitalization. This proportion continues to grow, with the cumulative net inflow surpassing $57.82 billion. It can be seen that the enthusiasm of traditional institutions in allocating Bitcoin has not diminished.
