A significant shift in investor sentiment has led to a massive outflow of $146 million from US Bitcoin spot ETFs, according to recent data from Farside Investors. This marks the third consecutive day of negative net inflows, with nine out of ten US Bitcoin ETFs experiencing zero or negative single-day flows. The cumulative total net inflow after 109 trading days has dropped to below $15 billion.

The largest outflow was seen in the Fidelity Wise Origin Bitcoin Fund (FBTC), with a net outflow of $92 million, followed by ARK 21Shares Bitcoin ETF (ARKB) with net outflows of $50 million. Other ETFs, such as VanEck Bitcoin Trust (HODL) and Grayscale Bitcoin Trust (GBTC), also experienced significant outflows. This development highlights a changing investor attitude towards Bitcoin ETFs amidst a volatile market.

The price of Bitcoin (BTC) has been affected by this market dynamic, currently standing at $65,567.92 with a 24-hour trading volume of $36.6 billion. This represents a -0.67% price decline in the last 24 hours and a -3.50% decline over the past 7 days. Bitcoin's market cap is valued at $1.2 trillion, with a circulating supply of 20 million BTC.

The current price trend indicates a bearish near-term but bullish longer-term outlook. A break above the 50-day EMA could give bulls a chance to reach the $69,000 resistance level, while a breakout from this level could signal a move toward the $73,808 all-time high. Investors should keep an eye on US retail sales figures, FOMC Member chatter, and US BTC-spot ETF market flow trends, as these factors could influence market dynamics.

In conclusion, the surge in Bitcoin ETF outflows to $146 million reflects a significant shift in investor sentiment. As the market continues to fluctuate, investors should be cautious and monitor key factors that could impact the price of Bitcoin. The current price levels are critical, and a rebound to $70,000 or an extended pullback to $60,000 is possible.
