On September 3rd, physical Bitcoin ETFs witnessed their biggest outflows in nearly four months, amounting to over $287 million. This is the largest single-day outflow since May, indicating a significant drop in investor enthusiasm for Bitcoin ETFs, leading to a shrinkage of total assets in physical funds to $52.6 billion, down by $10 billion from its peak. As Bitcoin's price has declined from its March high of $73,000 to around $58,400 currently, the decline on Tuesday was nearly 3%. Similarly, Ethereum's physical ETFs were also affected, with related funds experiencing outflows of over $52 million. Despite the fact that Wall Street banks and hedge fund investors still held onto Bitcoin ETFs during the second quarter, the overall flow of funds showed signs of weakness.
