U.S. spot bitcoin and ether exchange-traded funds faced a total of $582 million in net outflows on Monday, marking the highest since Nov. 20, as cryptocurrency markets dipped, bringing bitcoin down to a low of $85,100.
The bitcoin ETFs experienced $357.6 million in outflows, the most significant in almost two weeks, while ether ETFs witnessed $224.8 million exit over a third consecutive day of withdrawals, according to Farside data.
According to Velo data, Monday ranks as the third-worst performing weekday for bitcoin in the last 12 months, following behind Thursday and Friday regarding average returns. Notably, several major local lows for bitcoin in 2025 have also occurred on Mondays, a trend illustrated in the chart below.
A critical aspect to observe for potential bitcoin support is the U.S. ETF cost basis. This indicates the average purchase price of bitcoin held by spot ETFs, computed by aggregating daily ETF inflows with bitcoin’s price at each deposit, creating a running average.
