The year 2025 is shaping up to be a pivotal moment for Bitcoin, echoing the transformative momentum seen during its historic 2020 bull run. While retail investors surged into the market, chasing new price highs, blockchain data reveals a more strategic story beneath the surface—one where whales, institutions, and professional traders quietly capitalized on retail enthusiasm.
This deep dive analyzes trading behavior across different investor tiers—from small retail participants to large institutional players—using real market data from August to November 2020. By examining transaction volumes, trade directions, and price trends, we uncover how market sentiment shifted as Bitcoin climbed from $10,000 to nearly $20,000.
Understanding Market Behavior Through Transaction Data
To decode who was buying and selling during Bitcoin’s rally, we analyzed daily trading data from a major exchange (BTC/USDT pair) between August 1 and November 30. Transactions were grouped into five size brackets:
- Below 0.5 BTC
- 0.5–2 BTC
- 2–5 BTC
- 5–10 BTC
- 10+ BTC
These ranges serve as proxies for different types of market participants: retail traders, professional traders, large holders (whales), and institutions.
We also used the taker_side_sell metric to determine whether each transaction was initiated as a buy or sell—critical for understanding true market pressure. Finally, we compared net buying/selling activity against Bitcoin’s Volume-Weighted Average Price (VWAP), offering a clearer picture of how different groups reacted at various price levels.
Retail Traders (Below 0.5 BTC): The Trend Chasers
Retail investors dominate in volume count, with trades under 0.5 BTC making up the largest share of daily transactions. At $10,000 per BTC, this represents transactions between $10 and $5,000.
Over the 122-day period:
- Net sellers on 65 days (53.28% of the time)
- Net buyers on 57 days

Behavioral Insights:
- In August, when Bitcoin traded above $11,000, retail traders were predominantly **selling**, likely anticipating a pullback to $10,000.
- From September onward, as prices stabilized around $10,000, they shifted to net buying.
- Buying interest peaked near $15,000, but confidence waned as prices climbed higher.
- During the Thanksgiving-week crash (late November), retail traders panicked and sold off, only cautiously re-entering during rebounds.
This pattern confirms a classic fear-of-missing-out (FOMO) cycle: buying after significant gains and selling during corrections.
Key Takeaway:
Retail traders tend to follow trends rather than lead them. Their behavior often amplifies volatility—buying high and selling low—making timing crucial for long-term success.
Professional Traders (0.5–2 BTC): Strategic Entry and Exit Points
Trades between 0.5 and 2 BTC likely represent active traders who use technical analysis, chart patterns, and algorithmic strategies. These are not casual investors but those treating crypto trading as a serious pursuit.
Over the same period:
- Net sellers on 80 days (65.57%)
- Became net buyers only in October and November
Market Observations:
- Heavy selling pressure from August to September as prices dropped from $11,000 to $10,000.
- A clear shift occurred in October when Bitcoin broke above $11,500—professional traders began accumulating.
- Major buying spikes occurred at $11,500 and $12,500 (October 18–21).
- Selling resurfaced around $13,500 and $15,300 (early November).
- Sustained buying resumed after $15,000, continuing toward all-time highs.
Notably, Fibonacci retracement levels (50%, 61.8%, 78.6%) aligned closely with these key price zones—suggesting professionals were using established technical models to guide decisions.
Why It Matters:
This group demonstrates discipline and strategy. They sold into early strength but re-entered at psychologically significant levels, avoiding emotional trades.
Mid-Tier Whales (2–5 BTC & 5–10 BTC): Taking Profits at the Top
Transactions in the 2–5 BTC and 5–10 BTC ranges signal larger players—potentially early adopters, high-net-worth individuals, or smaller institutions.
Key Stats:
- 2–5 BTC group: Net sellers on 86 days (73.5% of the time)
- 5–10 BTC group: Net sellers on 85 days (72.65%)
Both groups maintained a consistent profit-taking strategy throughout the rally.
Price-Level Behavior:
- Accumulated positions below $11,500 (especially in October)
- Began systematic selling as prices rose past $13,000
- Intensified sell-offs after $15,000, peaking near all-time highs
An interesting divergence emerged in late November:
- On November 24, both mid-tier whale groups showed a rare surge in net buying, coinciding with a sharp $1,000 green candle.
- This buying preceded a bottom formation at ~$16,000 and a strong reversal.
This suggests that even profit-taking whales recognized value during sudden dips—buying back in when fear gripped the market.
Large Institutions & Major Whales (10+ BTC): Buying Low, Selling High
The largest transactions—10 BTC or more—are most likely executed by institutional investors or major holders with deep market influence.
Despite representing the smallest number of trades:
- Only net sellers on 64 out of 122 days (54.7%)
- Showed a balanced yet strategic approach
Strategic Moves:
- Strong net buying from mid-September to late October, while prices ranged between $10,000 and $11,500
- Minimal selling during October’s breakout—unlike smaller whales
- Some accumulation near $15,500
- Notably joined the November 24–29 buying wave, stepping in during the post-Thanksgiving dip

The Big Picture:
Large players bought aggressively at lower levels and sold into strength—but unlike mid-tier whales, they remained active buyers even near peaks when volatility created bargains.
Their behavior reflects sophisticated risk management: accumulating quietly during consolidation and capitalizing on panic-driven selloffs.
Monthly Breakdown: Shifting Sentiment Across Investor Tiers
| Month | Retail | Pros | Mid Whales | Large Whales |
|---|---|---|---|---|
| Aug | – | – | – | – |
| Sep | + | – | – | Neutral |
| Oct | + | + | – (less) | + |
| Nov | + | + | – | Mixed |
- (+ = Net Buyer; – = Net Seller)
Summary:
- August: Widespread profit-taking after breaking $11K
- September: Retail stepped in at $10K; others stayed cautious
- October: Momentum built; pros and large whales turned bullish
- November: Retail FOMO peaked; whales took profits
Final Week of November: Who Was Buying at the Peak?
When Bitcoin hit its then-record high (~$19,850) on November 30:
- Retail and pros: Still buying
- Mid-tier whales (2–5 BTC): Heaviest sellers
- Large whales (1+ BTC): Selective buyers during dip recovery
During the Thanksgiving crash (Nov 26), when price plunged from $19K to $16K:
- Everyone else panicked
- Only large whales and institutions increased buying
This confirms a recurring pattern: big players exploit fear to acquire assets others are dumping.
Frequently Asked Questions (FAQ)
Q: What defines a "whale" in cryptocurrency markets?
A: While there's no fixed threshold, a whale typically holds enough Bitcoin to influence market prices through large trades. In practice, anyone trading 2+ BTC regularly may be considered a whale.
Q: Why do retail traders often lose money in bull markets?
A: Due to emotional trading—buying after price surges and selling during dips. Without strategy or discipline, retail investors amplify volatility instead of profiting from it.
Q: Do whales manipulate Bitcoin prices?
A: Not directly—but their large buy/sell orders impact liquidity and can trigger cascading price movements. Their timing often reflects superior information or technical analysis.
Q: Can retail investors beat the whales?
A: Yes—by adopting long-term strategies like dollar-cost averaging (DCA), avoiding FOMO, and studying on-chain data to spot institutional activity.
Q: Is it too late to invest in Bitcoin now?
A: Timing the market is risky. Instead of chasing peaks, focus on gradual accumulation and holding through cycles for potential long-term gains.

Conclusion: The Real Winners of the Bull Run
Data doesn’t lie: while retail investors drove demand with FOMO-fueled purchases near all-time highs, it was the whales and institutions who reaped the greatest rewards.
They bought low during consolidation phases ($10K–$11.5K), sold into strength ($13K–$19K), and opportunistically bought back during panic drops—like Thanksgiving week 2025.
Retail traders weren’t wrong to participate—but without strategy, they became fuel for the rally rather than its beneficiaries.
For today’s investors, the lesson is clear: follow the data, not the hype. Understand market structure. Watch whale movements. And remember—the smartest money isn’t always the fastest; it’s the most patient.
As Bitcoin continues evolving in 2025 and beyond, those who learn from past cycles will be best positioned to thrive—not just survive—the next bull run.
