Bitcoin (BTC) traded lower Monday, extending a week of heightened volatility as markets shifted into a risk-off stance.
Notably, the asset has now declined nearly 6% over the past seven days, wiping out an estimated $100 billion in market value as prices slipped from around $78,000 to the low $70,000 range.
Last week, CryptoQuant analysts cited a slowdown in institutional accumulation as a key driver of the pullback. At the same time, profit-taking has emerged, with Strategy selling $2.5 million worth of BTC on May 30 after a three-year pause. The shift has weakened dip-buying support and increased sensitivity to sell pressure, amplifying short-term volatility.
That said, Sentiment weakened further after reports of a large institutional Bitcoin transaction with $1.26 billion in exposure, adding to concerns about rising risk aversion in the market.
Notably, the transaction occurred on May 26, when a single counterparty sold 29.21 million IBIT shares in an off-exchange block at $43.16 per share, totaling approximately $1.26 billion in notional value, according to NYDIG research.
 
According to the firm, the seller accepted a $1.01 discount off the prevailing market price of $44.17, effectively paying a 2.3% execution cost (about $29.5 million) for immediate liquidity.
NYDIG’s analysis pointed to a simple explanation. A large investor was exiting a major Bitcoin-linked position quickly, rather than unwinding a hedged or arbitrage trade. The scale of the block, the lack of related activity in CME futures, and the steep discount accepted to complete the sale all suggested urgency, with the seller prioritizing speed over price.
The report also highlighted that the trade happened during a weaker market phase, when spot Bitcoin ETFs were already seeing several days of outflows.
Commenting, analyst NicCrypto also noted that the structure of the trade pointed to urgency rather than a gradual, planned repositioning.
“This wasn’t a strategy…. It was a large investor who wanted out quickly and was willing to pay for the privilege,” He stated.
However, interpretation of the move remains divided. Some analysts argued the transaction does not necessarily represent outright bearish positioning, suggesting instead that large blocks like this can reflect internal transfer between institutional counterparties rather than pure market selling pressure.
Analyst “Cryptothedoggy” suggested the transaction was not a simple exit into the open market but rather a privately matched trade between large counterparties.
In his view, the Bitcoin exposure did not disappear from the system but was instead transferred almost instantly to another institutional buyer, implying rotation rather than liquidation.
This perspective suggests that what appears to be a massive sell-off may actually reflect structural repositioning of ETF-linked exposure, in which one large holder exits while another takes on the position at scale.
At press time, BTC was trading at $71,493, reflecting a 2.91% decline in the past 24 hours.
