For the first time since the introduction of spot Bitcoin (CRYPTO:BTC) ETFs in the United States, the ARK 21shares Bitcoin ETF, spearheaded by Cathie Wood, witnessed a significant event as its daily outflow reached $87.5 million on April 2.

This outflow surpassed that of the Grayscale Bitcoin Trust, marking a historic milestone in the cryptocurrency investment landscape.

Despite this notable outflow and a loss on the preceding day, the ARK 21shares Bitcoin ETF continues to hold its position as the third-largest of its kind.

The event underscores a unique shift in investor behavior and preferences within the evolving Bitcoin ETF market.
