Last week saw notable movement in the U.S. spot ETF space. Bitcoin ETFs pulled in $459 million in net inflows between Dec. 29 and Jan. 2, with BlackRock's IBIT leading the charge at $324 million. That's a solid week for the world's largest cryptocurrency by market cap.

Ethereum told a different story—its spot ETFs experienced a $161 million weekly net outflow. The divergence between these two assets suggests investors are showing more conviction in Bitcoin at the moment, while taking some profits or rotating away from Ethereum positions.

These fund flows remain a key indicator of institutional appetite and retail sentiment in the digital asset space.
