Bitcoin has experienced four major bear markets, each declining 77–93% from its peak. Every bear market bottom has been confirmed by the same convergence of on-chain signals — signals that can be tracked in real time before prices recover.
25 on-chain signals aggregated into a single daily P(bottom) score — free, no login.
Cause: Early exchange hacks, Mt.Gox security breach, speculative bubble pop
Cause: Mt.Gox collapse (850K BTC lost), China exchange ban, regulatory uncertainty
Cause: ICO bubble burst, SEC crackdown on token sales, macro risk-off
Cause: LUNA/Terra collapse (May 2022), 3AC insolvency, FTX collapse (Nov 2022), Fed rate hikes
Bitcoin bear markets are not chaotic — they follow a recognizable on-chain pattern. Understanding which phase you're in determines whether to hold, reduce, or aggressively accumulate.
Price falls 20–40% from ATH. Most market participants believe this is a temporary correction. On-chain: long-term holders are still in profit (NUPL positive), MVRV Z-Score declining but still positive. Retail begins selling. Funding rates come off peak but remain positive.
Price falls 50–70% from ATH. Retail stops buying the dip. On-chain: MVRV Z-Score approaching 0, Puell Multiple declining toward miner stress levels, exchange inflows surge as holders exit. Funding rates turn negative. Headlines announce Bitcoin is dead.
Price falls 70–85%+ from ATH. Maximum pain for holders. On-chain signals enter extreme territory simultaneously: MVRV Z-Score below 0, NUPL in Capitulation zone, Puell Multiple below 0.5, Hash Ribbon in capitulation. This is the highest-probability buying window — when no one wants to buy.
Price stabilizes and begins recovering. The Hash Ribbon issues a recovery cross (miner capitulation ends). MVRV Z-Score returns above 0. Long-term holder supply reaches a peak. Retail hasn't returned — this is the accumulation phase before the next cycle.
Bitcoin bear markets have lasted 12–26 months from peak to confirmed bottom. The 2017–2018 bear market took 12 months to reach bottom. The 2021–2022 bear market took 12 months. Both were followed by recovery phases before the next major bull cycle. At the current pace of institutional adoption, bear market durations have been shortening each cycle.
A correction is typically defined as a 10–20% decline; a bear market is 20%+ decline sustained over time. Bitcoin's high volatility means 30–40% corrections occur even within bull markets. The distinction that matters is on-chain: are long-term holders accumulating or distributing? MVRV Z-Score, NUPL, and LTH supply ratio tell this story more accurately than price percentage alone.
Each bear market had a specific catalyst: Mt.Gox collapse (2015), ICO regulatory crackdown (2018), LUNA/Terra collapse + FTX implosion + Fed rate hikes (2022). However, the on-chain preconditions were consistent across all: MVRV Z-Score above 5, NUPL in Euphoria/Greed zone, and funding rates at extreme positive levels. The catalyst differs; the setup is always the same.
The Bitcoin DCA Calculator at btcdca.app compares signal-timed DCA against always-buy strategies with fair capital normalization. Historically, increasing DCA allocation when the Bitcoin Bottom Score is above 65% has outperformed blind always-buy strategies — but both have outperformed not buying at all. The key is avoiding over-allocation before signals confirm a bottom.
