Bitcoin's options market has undergone a significant shift, with the $70,000 strike call replacing the $80,000 call as the most popular play. This change could potentially slow Bitcoin's ascent above $70,000. The $60,000 put remains the most sought-after downside bet, suggesting a possible floor for Bitcoin's price. This shift in positioning has implications for dealers, who hold a 'net long gamma exposure' above $70,000. This means they would short or sell into strength above $70,000 to maintain market-neutral exposure, acting as a brake on Bitcoin's rapid rise. This dynamic is less pronounced in Ethereum, allowing it to rip much faster. The current market conditions, with Bitcoin trading near $64,100, down nearly 1% since midnight UTC, and other major cryptocurrencies nursing similar losses, highlight the risk of a sudden sell-off amid financial market shocks. However, buying in a quiet market at less than half of peak levels is a reasonable tactic for the coming days or weeks. This analysis raises a deeper question: How will this shift in options positioning impact Bitcoin's long-term trajectory and its relationship with other cryptocurrencies?
