US cryptocurrency spot ETF experienced a wave of concentrated outflows yesterday. According to market data, Bitcoin spot ETFs saw a single-day net outflow of nearly $358 million, marking the first overall fund outflow of the week. All 12 BTC ETF products declined across the board, with no exceptions of net inflows.

The biggest impact was on Fidelity's FBTC, which saw a outflow of $230 million in one day, equivalent to approximately 2,680 Bitcoins. Although this product performed well, its cumulative net inflow reached $11.94 billion, indicating that long-term investors remain optimistic. Next are products from Bitwise and Ark, which experienced outflows of $44.32 million and $34.49 million respectively. Grayscale's products were also not spared, with GBTC and HODL experiencing outflows of $27.51 million and $21.25 million.

Overall, the total net asset value of Bitcoin spot ETFs is currently around $112.27 billion, accounting for 6.56% of Bitcoin's total market cap, with a cumulative inflow of $57.55 billion. This shows that despite yesterday's volatility, the entire product ecosystem continues to grow steadily.

The situation for Ethereum spot ETFs is also not ideal. Yesterday, Ethereum spot ETFs recorded a net outflow of nearly $225 million, marking the third consecutive day of fund withdrawals. BlackRock's ETHA was withdrawn by $139 million, approximately 47,460 ETH, making it the product with the largest single-day outflow. Grayscale's ETHE and ETH experienced outflows of $35.10 million and $20.18 million respectively. Products from Bitwise, Fidelity, and VanEck also saw outflows ranging from hundreds of thousands to tens of millions of dollars.

The current total net asset value of Ethereum spot ETFs is $18.27 billion, accounting for 5.17% of Ethereum's total market cap. In the long term, the cumulative net inflow for these products has reached $12.86 billion, indicating that market enthusiasm for this sector remains strong. Short-term adjustments may simply be normal market fluctuations.
