Bitcoin broke through $71,000, carrying significance as a trend-strengthening signal. From a technical perspective, $71,000 sits at the edge of a historical high-density trading zone; after the breakthrough, selling pressure above is limited. On-chain data shows long-term holder positions are stable, exchanges continue to experience net outflows, and the market remains in the mid-to-late stage of a bull market continuation. At the macro level, expectations for a monetary policy shift are strengthening, and Bitcoin's dual characteristics as a risk asset and safe-haven asset are being repriced. Operationally, there are three approaches: trend followers can enter on pullbacks to $68,000-$70,000; swing traders should monitor derivatives metrics like funding rates and open interest to prevent overheating; long-term allocators should consider dollar-cost averaging or adding on dips. Risk points include leverage accumulation, regulatory surprises, and sentiment reversal. In high-price zones, returns and risks become increasingly asymmetric; focus should be on pacing and risk management rather than simply chasing rallies.
