What Is Bull Run in Crypto?

A bull run is an extended period of rising prices across crypto markets, typically 12-24 months long. Historical bull runs (2013, 2017, 2020-2021, 2024-2025) have driven Bitcoin 5-100x from cycle lows, with alts typically outperforming during the "altseason" later in the run. The term contrasts with "bear market" — the long, grinding downtrend that follows each peak.

Also known as: bull market, crypto bull run

Anatomy of a crypto bull run

The historical pattern rhymes:

  1. Accumulation — late in the preceding bear market, smart capital accumulates at low prices. Narratives shift quietly.
  2. Early bull — BTC leads, rising slowly. Capital inflows start. Media coverage tentative.
  3. Momentum phase — price action attracts more capital. FOMO enters the chat. Narratives consolidate around 1-2 big themes.
  4. Altseason — after BTC has rallied significantly, capital rotates into alts. ETH first, then DeFi blue-chips, then smaller caps and memecoins.
  5. Peak euphoria — retail participation peaks. Taxi drivers talk about crypto. Cover of Time magazine. Leverage extreme.
  6. Distribution — smart capital exits. Market churns at the top for weeks or months.
  7. Decline — prices start falling. Early drops look like buying opportunities; they’re not. Bear market begins.

Historical bull runs

  • 2013 — Bitcoin from ~$13 to ~$1,100 over ~11 months. First mainstream attention.
  • 2017 — BTC from ~$1,000 to ~$20,000 over ~12 months. ICO mania. Massive alt outperformance.
  • 2020-2021 — BTC from ~$3,800 (COVID low) to ~$69,000. DeFi Summer, NFT boom, Ethereum ecosystem explosion. Two peaks (April and November 2021).
  • 2024-2025 — BTC from ~$16,000 (Nov 2022 low) to ~$108,000 at recent peaks. Driven by spot-ETF flows and institutional entry. Alt cycle more muted than previous.

Each cycle has produced smaller multiples than the last as the asset class has matured and grown.

Narrative patterns

Each cycle gets identified by its dominant narratives:

  • 2013 — Bitcoin as e-gold; Silk Road aftermath.
  • 2017 — ICOs, “utility tokens,” blockchain-for-everything.
  • 2020-2021 — DeFi, NFTs, Metaverse, layer-1 competition (ETH, SOL, AVAX, LUNA).
  • 2024-2025 — Spot ETFs, Bitcoin-as-institutional-asset, memecoin mania on Solana, restaking, AI-x-crypto, real-world assets.

Narratives drive sector rotations within the broader rally. Tokens aligned with the dominant narrative outperform; those aligned with the previous cycle’s narrative underperform.

Risks and considerations

  • Peaks are unclear in real time. Every cycle has “is this the top?” moments that turned out to be mid-run pauses, followed by further runs. Peaks are obvious only in retrospect.
  • Leverage kills during peaks. Retail leverage at cycle peaks is the single most-reliable indicator of an impending correction. When funding rates hit all-time highs, the flush is close.
  • Rotation is relentless. Yesterday’s leader is often today’s laggard. Holding yesterday’s winners into today’s bull run often underperforms.
  • Altseason is unreliable. Every cycle since 2017 has had altseason; 2024-2025 had a muted one where many alts never recovered their prior-cycle highs despite BTC hitting new highs.

For holders: take partial profits on the way up. Don’t trust “this time is different” for either the upside or the downside. For traders: rotate actively, watch leverage indicators, stay attentive to narrative shifts. Every bull run ends in a bear market; plan for the reversal while enjoying the rally.
