US-based spot Bitcoin ETFs have experienced significant outflows, totaling nearly $1.2 billion over three days, marking the longest outflow streak since the re-election period of former President Donald Trump. This streak resulted in a $10.7 billion decrease in the total value of these funds. Despite these outflows, the overall value of the funds ended slightly higher than at the beginning of December. While most funds saw continuous outflows, some like BlackRock's IBIT reported less significant losses. Concurrently, Ethereum ETFs saw minor net outflows but remained relatively stable in value.
