Today is November 21st, BTC price is 82,900. 1. Apologies for the loss on yesterday's long position! Structurally, both the 4-hour and 12-hour charts showed upward demand, but then U.S. stocks crashed, triggering stop-loss exits. 2. NVIDIA delivered its best earnings report ever, but profit-taking caused a sell-off. The U.S. stock AI bubble sparked panic selling, coupled with non-farm payroll data reducing expectations for a December rate cut. 3. BTC saw a big spike, with total contract open interest dropping by 10%. Keep an eye on U.S. stock movements tonight. Suggested spot buys: SOL, DOGE.
