Options Signal — A “large bullish call spread” (bull call spread) bought by a trader or a group of traders, targeting to point to $72,000 before month-end, is the most direct price expression in the derivatives market for the accumulation thesis by institutions and whales. A large bullish call spread — buying a call option with a lower strike price and selling a call option with a higher strike price — is the options structure used when traders are highly confident in an upside target within a specific time frame, while also managing the cost of the premium. With the current price at $66,382, reaching $72,000 before month-end implies an expected rise of about 8.5% over the next 10 days; and achieving this goal would require either a more dovish-than-expected FOMC surprise, or a sustained Iran ceasefire, or both occurring simultaneously. Analytically, the $72,000 target is equally important because it sits above the “$81,000 trend reversal confirmation level” identified by technical analysts — a level viewed as the price at which the downtrend from October’s historical high of $120,608 will be structurally broken. A month-end print of $72,000 would represent Bitcoin’s most aggressive short-term rebound since the ATH run in October–November 2025, and would validate the argument that “the June low at $57,750 was the cycle bottom.” $BTC $ETH $SOL
