[Glassnode: Bitcoin recently retested the $75,000 strike price, market direction remains uncertain] Deep Tide TechFlow reports that on May 29, Glassnode posted an analysis on the X platform stating that Bitcoin recently retested the $75,000 strike price. This area previously accumulated nearly $8 billion in short Gamma positions, temporarily pushing BTC prices down to around $72,500 before the expiration of this round of options. With today's large-scale options expiration completed, the market's Gamma structure has begun to reconstruct. Data shows that during BTC's decline, the ATM implied volatility (IV) briefly rose, with 1-week IV surpassing 35%, but quickly fell back to around 32%. Long-term IV also declined, indicating that the market views this fluctuation as a "controlled adjustment." In terms of capital flow, the structure of options buying and selling over the past seven days has been almost completely balanced, with the proportion of call and put options bought and sold each close to 25%. This reflects the market's lack of clear directional bets following the recent downturn.
