US Bitcoin ETFs Sold Over 19,000 BTC Last Week
U.S. spot Bitcoin ETFs recorded approximately $1.42 billion in net outflows during the week ended May 29. It marked one of the largest weekly withdrawals from Bitcoin products this year.
Collectively, spot Bitcoin ETFs sold an estimated 19,021 BTC during the week. That’s equivalent to roughly 42 days of newly mined Bitcoin supply. Among major issuers, BlackRock recorded the largest reduction in holdings, selling approximately 12,757 BTC, worth $966 million.

Bitcoin ETFs Withdraw $4 Billion In Three Weeks
Santiment reported that U.S. spot Bitcoin ETFs have recorded over $4.01B in cumulative net outflows since May 7.
Blockchain analytics firm noted that historical data shows major ETF inflow spikes have frequently occurred near local market tops. On the other hand, significant outflows have often followed with BTC price rebounds.
The firm highlighted a nearly $904 million outflow day in November 2025. This occurred close to a major market bottom before Bitcoin recovered. Santiment analysts believe that the current three-week stretch of more than $4 billion in ETF outflows could act as a contrarian signal.
The analysts noted that the scale of recent withdrawals suggests many investors have already reduced exposure. This indicates that market is already much closer to the local bottom.
BTC Price Tests Crucial Support, Is $50,000 Coming?
The BTC price has clearly been in a macro downtrend. Many experts believe that Bitcoin could reach another low before resuming any meaningful uptrend to an all-time high.
Popular analyst Ali Martinez noted that he is closely monitoring the $72,650 level for Bitcoin. It’s a key support zone identified by the MVRV pricing bands.
According to Martinez, maintaining support above this level would help preserve Bitcoin’s current market structure. However, a breakdown below $72,650 could lead to a deeper correction for BTC price.
The analyst added that the support level may fail. If this happens, the next major demand zone for Bitcoin lies between $54,300 and $51,000.
Another analyst Plan B, who popularized the stock-to-flow (S2F)said that Bitcoin closed the month of May at $73,568. However, market participants remain divided on whether the February low near $60,000 marked the cycle bottom.
According to PlanB, investor sentiment is currently split. Some are expecting a BTC price recovery from the February lows. At the same time, others anticipate the continuation of a broader bearish trend.
The analyst stated that current market data does not yet indicate a confirmed bottom formation. As a result, he believes there is a greater than 50% probability that Bitcoin could decline further.
PlanB added that a deeper correction could push Bitcoin below its 200-week moving average near $61,000. Furthermore, the realized price of around $53,000 is another key downside level to watch.
