Four iterations: How Bitcoin bull market cycles shape the crypto market landscape

Since its inception in 2009, Bitcoin has experienced multiple rounds of spectacular bull markets and brutal bear markets. Behind every price surge lies deep logic involving market psychology, technological evolution, and policy shifts. For participants aiming to seize the bull run opportunities, understanding these cyclical patterns is crucial. This article will deeply review four iconic bull market phases, revealing the core forces driving Bitcoin’s rise.

The Essence of Bull Markets: From Scarcity to Consensus Upgrades

Bitcoin’s bull markets do not occur out of thin air but are the result of resonance among multiple factors. Broadly speaking, a bull run features: sustained price increases, significant trading volume expansion, on-chain activity surges, and social media hype.

Compared to traditional stock markets, Bitcoin’s volatility during bull markets is more intense—doubling in a short period or halving. This extreme fluctuation stems from highly emotional market participants and relatively scarce liquidity.

The halving event is the core mechanism driving bull markets. The Bitcoin network triggers a halving approximately every four years, reducing miners’ rewards by half. Historical data shows:

• After the 2012 halving, BTC surged by 5,200%
• After the 2016 halving, it increased by 315%
• After the 2020 halving, it rose by 230%

This is because halving directly compresses new coin supply, and with demand remaining stable or increasing, prices inevitably trend upward.

2013: The First Wild Awakening of the Grassroots

The Bitcoin of 2013 is a classic grassroots investment story. From a surge to $145 in May to $1,200 in December, a 730% increase. This rally fundamentally changed public perception of digital currencies.

Driving forces at that time included:

• The Cyprus banking crisis triggered anxiety over asset safety, prompting some investors to turn to decentralized assets like Bitcoin
• Media coverage of Bitcoin’s rapid rise amplified “FOMO”
• Trading infrastructure was still primitive but enough to attract the first retail investors

Black Swan Event: Mt. Gox Collapse. This exchange, handling 70% of global Bitcoin transactions, encountered security breaches in early 2014 and eventually went bankrupt. The event shattered market confidence, causing Bitcoin to fall below $300, a decline of over 75%.

This lesson proved that even with strong fundamentals, market risk events can reverse an entire bull trend.

2017: Retail Frenzy and Regulatory Backlash

2017 marked the era of “全民参与” (mass participation) in crypto markets. Bitcoin soared from $1,000 at the start of the year to $20,000, a 1,900% increase. During this period, even non-technical investors discussed cryptocurrencies, and conversations about coin prices filled tables and subway rides.

Factors fueling this frenzy:

• The ICO (Initial Coin Offering) boom attracted millions of new funds into the crypto ecosystem, which ultimately flowed into Bitcoin
• Increased competition among exchanges, with new platforms lowering entry barriers for retail investors
• Media coverage exploded exponentially, creating a positive feedback loop: price rises → media reports → more entrants → further rises

Daily trading volume jumped from $200M at the start of the year to over $15B by year-end.

But the glory was short-lived. In early 2018, China, South Korea, and others tightened regulations; the US SEC announced increased scrutiny. By December 2018, Bitcoin dropped to $3,200, an 84% decline from its peak. Retail investors paid a heavy tuition fee.

This episode warns us: regulatory shifts can swiftly destroy long-standing market enthusiasm.

2020-2021: Institutional Entry Reshapes the Game

The bull run of 2020-2021 was of a completely different quality. Bitcoin climbed from $8,000 to $64,000 (+700%), then hit a new high of $69,000. This time, the drivers were no longer retail investors but US-listed corporations.

Turning points:

• MicroStrategy announced its allocation of funds into Bitcoin first
• Tesla, Square, and other tech giants followed suit
• By the end of 2021, these institutions held over 125,000 BTC

Policy catalysts: The US Commodity Futures Trading Commission (CFTC) approved Bitcoin futures at the end of 2020, and several countries launched related products, opening the door for institutional compliance.

Narrative upgrade: From “speculative bubble” to “digital gold” and “inflation hedge.” CEOs of major firms began discussing Bitcoin’s strategic value in financial reports, prompting middle-aged and older wealth managers to take it seriously.

The mid-2021 high of $64,000 then retraced to $30,000 (-53%), reminding the market: even with institutional backing, risks remain.

2024-2025: The Era of ETFs and New Patterns

The current bull run features policy compliance and asset class standardization.

In January 2024, the US SEC approved a spot Bitcoin ETF, marking a historic moment—ordinary investors can now hold Bitcoin exposure directly through 401(k) retirement accounts or brokerage platforms without managing private keys themselves.

Data confirms:

• As of November, net inflows into all spot Bitcoin ETFs exceeded $28B, surpassing the same period for gold ETFs
• BlackRock’s iShares Bitcoin Trust (IBIT) alone holds over 467,000 BTC
• The total holdings of Bitcoin ETFs worldwide have surpassed 1 million BTC

Meanwhile, institutions like MicroStrategy and Michael Saylor continue aggressive accumulation. On-chain data in 2024 shows institutional holdings reaching record highs.

Latest update: As of December 2025, Bitcoin trades at $88.65K, a retracement from the all-time high of $126.08K but up 122% from the start of the year’s $40K. 24-hour trading volume is $863.89M, with a circulating market cap of $1.77T. This indicates that even with price adjustments, market participation and capital levels remain high.

New risk factors:

• Liquidation pressure from high leverage trading
• Rate policy shifts potentially weakening risk asset appetite
• Ongoing environmental concerns and ESG funds distancing from Bitcoin
• Regulatory uncertainties persist

Recognizing Technical Signals and On-Chain Footprints of Bull Markets

To catch the next rally, early identification methods are essential.

Technical signals:

• RSI (Relative Strength Index) breaking above 70 indicates strong buying momentum
• The 50-day moving average crossing above the 200-day moving average (“Golden Cross”) often signals a long-term uptrend
• Volume confirmation: price hitting new highs with moderate volume may be false signals; true breakouts are accompanied by volume surges

On-chain data:

• Surge in Bitcoin outflows from exchanges suggests accumulation by large holders (HODLing)
• Significant inflows of stablecoins into exchanges hint at large capital preparations
• Movements of whale wallets (addresses with over 100 BTC)
• Unrealized profit ratios (URPD) and other derivatives indicators reflect overall market cost basis

Macro context:

• Central bank liquidity policies (rate cuts tend to favor risk assets)
• Geopolitical conflicts increasing risk aversion
• Major legislative or regulatory signals

In 2024-2025, RSI frequently exceeds 70, and the 50-day MA remains well above the 200-day MA—classic bull market features.

Future Drivers: Policy, Technology, Supply

Policy dimension: US Senator Cynthia Lummis proposed the “2024 Bitcoin Act,” suggesting the Treasury Department purchase 1 million BTC over five years as strategic reserves. While unlikely in the short term, such proposals reflect shifting political attitudes.

If implemented, it could usher in an era of “sovereign wealth allocation of Bitcoin.” Countries like Bhutan (over 13,000 BTC) and El Salvador (about 5,875 BTC) are already testing waters. If major nations follow, global demand for Bitcoin will grow exponentially.

Technological dimension: Bitcoin is about to upgrade with OP_CAT. This feature enables more complex smart contracts, supporting Layer-2 scaling solutions that could process thousands of transactions per second. It opens the door for DeFi applications on Bitcoin, directly competing with Ethereum.

Supported by broad developer community backing, this upgrade may soon be realized, unlocking new application scenarios for Bitcoin.

Supply dimension: The next halving is expected around 2028, which will halve new coin issuance again. If by then institutional holdings continue to grow and ETF scales expand, scarcity will reach its peak, fueling the bull market.

Practical Checklist for Investors

In facing a bull run, ordinary investors should:

Step 1: Knowledge Preparation

• Deeply understand Bitcoin’s operation; avoid blind following
• Study historical price cycles to assess if you can stay calm
• Focus on key events like halving, regulatory developments, and major institutional holdings

Step 2: Risk Assessment and Position Management

• Clarify your risk tolerance. If a 50% loss overnight keeps you awake, don’t be fully invested
• Consider dollar-cost averaging rather than all-in at once to reduce high-position risk
• Set stop-loss orders and establish psychological bottom lines

Step 3: Platform Selection

• Prefer licensed, transparent exchanges; avoid chasing high yields
• Confirm platform security: two-factor authentication, cold storage, regular audits
• For long-term holdings, consider self-custody wallets

Step 4: Security First

• Hardware wallets (Ledger, Trezor) are standard for cold storage
• Remember private keys or seed phrases; store securely (avoid screenshots, emails)
• Regularly withdraw coins from exchanges to reduce hacking risk

Step 5: Tax Preparation

• Record all transactions: dates, amounts, cost basis according to local laws
• Consult tax professionals to understand capital gains taxes
• Stay updated on changing regulations

Step 6: Psychological Readiness

• Don’t FOMO into positions after others get rich
• Avoid panic buying at market bottoms; bottoms are often lower than expected
• Follow authoritative news sources; filter out emotional or unreliable info

Cycles and Risk Warnings

Bitcoin’s cyclical nature is increasingly evident:

• 2013: Asset awakening
• 2017: Retail frenzy
• 2021: Institutional confirmation
• 2024-25: Asset standardization

Each phase involves participant upgrades: from tech geeks → retail → institutions → mainstream investors.

But beware:

• High leverage trading often leads to tragedies in late bull markets (lessons from late 2017 and mid-2021)
• Regulatory tightening often occurs at market peaks
• Macro shifts (interest rate hikes, recessions) can instantly break bull narratives
• New competing coins may divert capital

Next Stop: When to Start

While precise timing of the bull run’s start and end is impossible, history offers clear clues:

Halving cycles remain the most reliable reference. The fifth halving in 2028 will create scarcity on the supply side. If the global economy remains stable and policies continue to favor crypto, the next big rally will have a solid foundation.

In shorter cycles, the maturation of ETF ecosystems, increasing corporate holdings, and potential government adoption are gradually strengthening. Market sentiment indicators show a balanced state (50:50), often a prelude to major moves.

For investors wanting to participate, there’s no need to rush into the most frenetic moments—preparation before the trend is established is key. Monitoring halving schedules, tracking institutional holdings, and observing policy signals are all warning signs.

Summary

Bitcoin’s four major bull markets demonstrate a process evolving from high risk to institutionalized assets. From pure speculation in 2013 to index fund allocations in 2024, this process has reshaped the capital markets.

The next bull run is unlikely to grow as wildly as 2017 but will be more structured, with more diverse participants and smoother volatility due to institutional influence. But this does not mean opportunities are gone—in fact, a more mature market creates better entry conditions for serious investors.

The key is to stay alert, keep learning, and manage risks strictly. Bitcoin itself has not changed; the market’s maturity has. For well-prepared participants, the next upward cycle is within reach.
