I saw that in the last four months, more than $9 billion have been withdrawn from Bitcoin and Ether ETFs. It's a pretty significant movement to notice, considering how much attention these products have received in the institutional market.

The outflow of this size generally reflects changes in investors' strategies or possibly adjustments in portfolios. It's not something we see every day, so it's worth tracking where that money is going.

The interesting part is seeing how this impacts prices and overall sentiment. When there are movements of this volume, the market tends to react, although not always immediately. Some say it's a sign of weakness, others see it as an opportunity. In any case, these numbers are data that any trader should keep on their screen.
