A Cyprus bank crisis. An explosion of fundraising scams. A global pandemic followed by unprecedented stimulus. A regulatory approval from the SEC.
These four unrelated events, separated by years and continents, share something remarkable. Each one became the spark that ignited one of crypto’s biggest bull runs. None of them had anything to do with blockchain technology directly. Yet each triggered months of explosive price growth that reshaped the entire industry.
Understanding crypto’s bull run history is not about predicting the next one with certainty — nobody can do that reliably. However, recognising the patterns across previous cycles helps investors understand what typically drives these rallies, how long they tend to last, and what usually follows.
This is the complete story of crypto’s major bull runs, from 2013 to today.
What Is a Crypto Bull Run?
A bull run is a sustained period of rising prices across the crypto market, typically accompanied by surging trading volumes, intense media coverage, growing retail participation, and widespread optimism about future gains. For a deeper definition of this phase, read our what is bull market guide.
Crypto bull runs differ from traditional stock market rallies in one crucial way: their scale. While a strong year for the S&P 500 might deliver 20-30% gains, crypto bull runs have historically delivered returns measured in the thousands of percent for Bitcoin, and even larger multiples for smaller altcoins.
Historically, major bull runs have lasted between 11 and 18 months from initial surge to peak. Each cycle has built on infrastructure, awareness, and capital from the previous one — even as each individual rally was driven by its own unique catalyst.
The 2013 Bull Run: Bitcoin’s First Mainstream Moment
Duration: Approximately 11 months Starting price: ~$13 (January 2013) Peak price: ~$1,163 (November-December 2013) Approximate gain: 9,000%+
The Catalyst
In March 2013, the small Mediterranean nation of Cyprus faced a severe banking crisis. To avoid a complete financial collapse, the government imposed a levy directly on bank deposits — effectively confiscating a portion of ordinary citizens’ savings to recapitalise failing banks.
The move shocked depositors across Europe. If a government could simply take money directly from bank accounts, what was actually safe? Interest in Bitcoin surged immediately, driven by a new audience seeking an alternative to traditional banking that no government could directly seize.
Furthermore, the launch of more accessible centralised exchanges — including early versions of platforms that would become Coinbase and Kraken — made buying Bitcoin significantly easier for new entrants. Previously, acquiring Bitcoin had required technical knowledge that excluded most ordinary investors.
What Happened
Bitcoin rose from under $100 in early 2013 to nearly $1,200 by December. This was crypto’s first genuine mainstream moment — the first time Bitcoin appeared regularly in news coverage, attracted meaningful retail interest, and demonstrated that a digital currency with no government backing could attract serious capital.
The subsequent crash was severe. Bitcoin fell from its $1,163 peak to approximately $175 by early 2015 — an 85% decline. The Mt. Gox exchange collapse in early 2014, where approximately 850,000 BTC were lost or stolen, compounded the downturn and shook confidence in the nascent industry significantly.
The 2017 Bull Run: The ICO Mania
Duration: Approximately 12 months Starting price: ~$1,000 (January 2017) Peak price: ~$19,891 (December 2017) Approximate gain: 1,900%+
The Catalyst
The 2017 bull run was driven by an entirely new phenomenon: the Initial Coin Offering (ICO). Ethereum’s smart contract capabilities made it possible for anyone to create a new token and raise funds from the public, often with nothing more than a whitepaper and a promising idea. To understand the original asset that started it all, read our what is Bitcoin guide.
Thousands of projects launched ICOs throughout 2017, promising to revolutionise everything from cloud storage to social media to supply chain logistics. Many raised millions of dollars within minutes of opening their token sales. The fundraising mechanism democratised access to venture-style investing — anyone with an internet connection could participate, not just accredited investors.
What Happened
Bitcoin climbed from around $1,000 in January to nearly $20,000 by December 2017 — but altcoins delivered even more dramatic gains. Ethereum rose from approximately $8 to over $1,400. Ripple’s XRP surged from $0.006 to $3.84 — a gain of over 60,000%.
The mania reached a point where companies could add “blockchain” to their name and see their stock price surge, regardless of whether they had any actual blockchain technology. FOMO (fear of missing out) became a defining feature of crypto culture during this period, as ordinary people watched friends and colleagues report extraordinary paper gains.
The subsequent crash was brutal and prolonged. Bitcoin fell from $19,891 to approximately $3,200 by December 2018 — an 84% decline. However, the damage to altcoins was far worse. Over 90% of ICO-funded tokens eventually became worthless, wiping out the vast majority of capital raised during the mania.
The 2020-2021 Bull Run: Institutions Arrive
Duration: Approximately 18 months — the longest cycle yet Starting price: ~$8,600 (May 2020) Peak price: ~$68,789 (November 2021) Approximate gain: 700%+
The Catalyst
The third major bull run emerged from an unprecedented global event: the COVID-19 pandemic. Governments and central banks worldwide responded with massive monetary stimulus — the US Federal Reserve’s balance sheet expanded dramatically, and interest rates fell to near zero across most developed economies.
This flood of liquidity, combined with growing concerns about currency debasement, pushed institutional investors toward Bitcoin as a hedge for the first time at meaningful scale. MicroStrategy began its now-famous corporate Bitcoin accumulation strategy in August 2020. Tesla announced a $1.5 billion Bitcoin purchase in February 2021. PayPal enabled cryptocurrency purchases for its massive user base.
Furthermore, this cycle coincided with the rise of DeFi (Decentralised Finance) and NFTs (Non-Fungible Tokens) — two genuinely new use cases that attracted both crypto-native users and entirely new audiences who had never previously engaged with crypto.
What Happened
Bitcoin rose from approximately $8,600 at its May 2020 halving to a peak of $68,789 in November 2021. This was crypto’s first cycle with significant institutional participation rather than primarily retail speculation. DeFi protocols collectively grew to over $100 billion in total value locked. NFT sales reached billions of dollars, with some individual digital artworks selling for tens of millions.
The subsequent correction, beginning in late 2021, proved to be the most damaging in crypto’s history — not just in percentage terms, but in the scale of institutional and systemic failures it exposed. This downturn marked one of crypto’s deepest bear markets. The Terra/LUNA ecosystem collapsed in May 2022, wiping out approximately $40 billion in value within days. The FTX exchange collapsed in November 2022, taking billions in user funds and several other crypto companies down with it. Read our FTX collapse explained guide for the full story. Bitcoin fell from $68,789 to approximately $15,500 — a 77% decline.
The 2024-2025 Bull Run: The ETF Era
Duration: Ongoing, with a peak reached in late 2025 Starting price: ~$63,800 (April 2024 halving) Peak price: ~$126,198 (October 2025) Approximate gain: 98%
The Catalyst
For the first time in crypto’s history, the catalyst for a major bull run came from a regulatory body rather than a crisis, a fundraising mechanism, or a new technology.
In January 2024, the US Securities and Exchange Commission approved the first spot Bitcoin ETFs. BlackRock, Fidelity, and nine other asset managers launched competing products simultaneously. This was a watershed moment — for the first time, traditional investors could gain Bitcoin exposure through a regulated brokerage account, without needing to manage private keys, choose an exchange, or navigate crypto-specific infrastructure at all.
Unusually, Bitcoin reached a new all-time high of approximately $73,800 in March 2024 — before the April 2024 halving even occurred. This had never happened in any previous cycle, where new highs had always come well after the halving event.
What Happened
Following the April 2024 halving, Bitcoin initially consolidated before accelerating sharply after Donald Trump’s election victory in November 2024, given his administration’s explicitly pro-crypto policy positioning. By October 2025, Bitcoin reached $126,198 — a new all-time high, though the percentage gain from the halving price was significantly smaller than any previous cycle.
This cycle has been distinguished by the depth of institutional infrastructure surrounding it. Spot ETFs absorbed billions in net inflows. Several sovereign nations began accumulating Bitcoin as a reserve asset. Corporate treasury adoption, pioneered by MicroStrategy in 2020, expanded significantly across other public companies.
By mid-2026, Bitcoin had pulled back to approximately $66,000 from its October 2025 peak — a correction of roughly 47%, notably smaller than the 84-85% corrections that followed the 2013 and 2017 cycles.
Side-by-Side Comparison: All Major Bull Runs
| Cycle | Duration | Catalyst | Gain | Peak Price | Subsequent Crash |
|---|---|---|---|---|---|
| 2013 | ~11 months | Cyprus banking crisis | ~9,000% | $1,163 | -85% |
| 2017 | ~12 months | ICO mania | ~1,900% | $19,891 | -84% |
| 2020-2021 | ~18 months | COVID stimulus + institutional adoption | ~700% | $68,789 | -77% |
| 2024-2025 | Ongoing | Spot Bitcoin ETF approval | ~98% | $126,198 | ~-47% (so far) |
The Pattern: Diminishing Returns, Growing Maturity
Looking across all four cycles, two clear trends emerge.
Percentage gains have consistently decreased. From roughly 9,000% in 2013, to 1,900% in 2017, to 700% in 2020-2021, to approximately 98% in the most recent cycle. This is a natural consequence of Bitcoin’s growing market capitalisation — moving a multi-trillion-dollar asset by the same percentage as a billion-dollar asset requires vastly more capital.
Crashes have become progressively less severe. The 85% and 84% corrections following the 2013 and 2017 cycles have given way to a 77% correction in 2022 and an approximately 47% correction so far in the current cycle. This suggests growing institutional participation and deeper market liquidity are providing a higher floor with each successive cycle.
Each cycle has been driven by a genuinely different catalyst. A banking crisis, a fundraising innovation, a pandemic response, and a regulatory approval — none of these repeat in an obviously predictable way. This is precisely why timing future bull runs based purely on calendar patterns is unreliable, even though the broader four-year halving cycle provides a loose framework.
The Role of Bitcoin Halving in Bull Run Timing
Three of the four major bull runs began within several months of a Bitcoin halving — the programmed event that cuts Bitcoin’s new supply issuance in half approximately every four years.
Historically, bull run peaks have arrived roughly 500 to 550 days after the corresponding halving. The 2012 halving preceded a peak reached 367 days later. The 2016 halving’s peak came 526 days later. The 2020 halving’s peak arrived 549 days later. The 2024 halving’s peak, in October 2025, came approximately 547 days after the event — remarkably consistent with the historical pattern.
This consistency has led many analysts to treat the halving as a loose framework for anticipating cycle timing, even though it is far from a guaranteed predictor. For a complete breakdown of how each halving has historically affected price, read our Bitcoin halving history guide.
What Typically Signals a Bull Run Is Underway
Across all four cycles, several recurring signs have preceded or accompanied major bull runs:
Rising trading volumes — sustained increases in daily trading activity across major exchanges, often beginning months before mainstream media attention arrives.
On-chain whale accumulation — large holders increasing their Bitcoin and Ethereum positions during periods of relatively low public attention, often visible through blockchain analytics tools.
Growing media coverage — as prices rise, mainstream financial and general news outlets begin covering crypto with increasing frequency, which often coincides with the acceleration phase of a bull run rather than its beginning.
New narrative or use case emergence — ICOs in 2017, DeFi and NFTs in 2020-2021, and ETF accessibility in 2024-2025 each introduced fresh reasons for new capital and new participants to enter the market.
Institutional or regulatory developments — corporate treasury purchases, ETF approvals, or favourable policy shifts have increasingly become bull run catalysts in more recent cycles, reflecting crypto’s growing integration with traditional finance.
FAQ
How long do crypto bull runs typically last?
Historical bull runs have lasted between 11 and 18 months from initial surge to peak. The 2013 run lasted approximately 11 months, the 2017 run approximately 12 months, and the 2020-2021 run extended to roughly 18 months — the longest cycle recorded so far.
What typically triggers a crypto bull run?
Each major cycle has had a distinct catalyst: the 2013 run followed the Cyprus banking crisis, the 2017 run was driven by ICO fundraising mania, the 2020-2021 run followed COVID-era monetary stimulus and institutional adoption, and the 2024-2025 run followed the approval of spot Bitcoin ETFs. There is no single universal trigger — each cycle has reflected the dominant forces of its specific period.
Is the four-year cycle theory reliable?
It provides a loose historical framework rather than a guaranteed rule. Three of the four major bull runs began within months of a Bitcoin halving and peaked roughly 500-550 days later. However, each cycle has also been shaped by unique external factors that the halving alone does not explain, making precise prediction unreliable.
How much have crypto bull run gains decreased over time?
Significantly. The 2013 cycle delivered approximately 9,000% gains, the 2017 cycle approximately 1,900%, the 2020-2021 cycle approximately 700%, and the 2024-2025 cycle approximately 98% so far. This diminishing pattern reflects Bitcoin’s growing market capitalisation, which requires increasingly large capital inflows to move the price by the same percentage.
What usually happens after a crypto bull run ends?
Historically, every major bull run has been followed by a significant correction — ranging from 77% to 85% in the first three cycles. These downturns, often called “crypto winters,” have typically lasted one to two years before the next cycle began. The current cycle’s correction, at approximately 47% so far, has been notably milder than its predecessors.
Final Word
Crypto’s history of bull runs reveals a market that has matured significantly with each cycle, even as the fundamental pattern of explosive growth followed by sharp correction has persisted.
What began with a Cyprus banking crisis driving a small, largely unknown digital currency to mainstream attention has evolved into a market where the world’s largest asset managers compete to offer regulated Bitcoin exposure to millions of traditional investors. The catalysts have changed completely. The underlying boom-and-bust rhythm has remained remarkably consistent.
For investors studying this history, the lesson is not to attempt precise timing based on calendar patterns alone. Instead, it is to understand that crypto bull runs are driven by genuine catalysts — technological innovation, macroeconomic shifts, regulatory developments — that emerge in their own time, layered on top of a market structure that has grown progressively more resilient with each passing cycle.
