Has Bitcoin Topped? Tops Never Ring a Bell — But They Leave These 5 Signals

Quick answer: Nobody can confirm a top in advance, but the 2013, 2017 and 2021 peaks left a checkable set of shared traits — price above 4x mining all-in cost, Pi Cycle moving averages near a cross, weekly RSI above 85 followed by divergence, a weekly MACD cross-down from high levels, and Fear & Greed pinned above 80 for weeks. The BTC Cycle Thermometer fuses these (plus the bottom-side indicators) into one 0-100 daily score: a reading above 80 means top traits are stacking.

Why top-calling is harder than bottom-calling

Bottoms have a cost floor (miner losses purge supply); tops are pure sentiment — bubbles can extend anywhere. Before both the Dec-2017 and Nov-2021 peaks, the crowd insisted "this time is different." Tops are also fleeting: the 2021 top zone lasted weeks, and by the time the decline was "confirmed," price was already down 30%. The answer isn't waiting for confirmation — it's staged profit-taking inside the top-trait zone.

The five signals, one by one

Price-to-mining-cost is the valuation anchor: every historic top sat in the 4-5x band (the logic here). Pi Cycle — the 111DMA crossing 2×350DMA — nailed all three major tops. Weekly RSI above 85 followed by divergence warns of momentum exhaustion; a weekly MACD cross-down confirms the turn. Warning-type plus confirmation-type beats any single indicator — the thermometer gives this top-side cluster over 40% combined weight.

In practice: turn exiting into discipline

When the thermometer enters overheating (60-80), stop adding and convert DCA into staged exits; above 80, accelerate. You don't need the exact peak — across all three tops, any staged selling inside the 80+ zone averaged close enough to the high. Let the indicator stack judge and discipline execute. Tops never ring a bell — but the thermometer turns red.
