Here’s something most Bitcoin traders miss: every time you check your wallet balance, you’re not looking at a single number stored in a database. You’re looking at the sum of dozens—sometimes hundreds—of discrete chunks of Bitcoin scattered across the blockchain like digital puzzle pieces. This is the UTXO model in action, and understanding it separates noise traders from those who read Bitcoin’s on-chain signals like a native language.
According to Glassnode data from early 2026, addresses holding Bitcoin now manage an average of 3.7 UTXOs each, but institutional wallets often juggle 50-200+ individual outputs. Why does this matter? Because UTXO patterns reveal accumulation behaviors, spending urgency, and transaction intent—signals that traditional balance checks completely miss. The UTXO model isn’t just Bitcoin’s accounting system. It’s a readable fingerprint of how smart money moves.
What Is the UTXO Model?
UTXO stands for “Unspent Transaction Output.” It’s Bitcoin’s fundamental way of tracking ownership and preventing double-spending. Unlike traditional bank accounts that maintain a running balance, Bitcoin’s UTXO model treats every transaction as a collection of discrete, indivisible chunks of value.
Think of UTXOs like physical cash. When you pay for a $12 coffee with a $20 bill, you don’t split the bill in half. You hand over the entire $20 and receive $8 in change. Bitcoin works the same way: you spend entire UTXOs and receive “change” as new UTXOs.
The Technical Definition
A UTXO is an output from a previous Bitcoin transaction that:
- Has been received by an address
- Has not yet been spent as an input in another transaction
- Represents a specific amount of Bitcoin
- Can only be spent in its entirety (not partially)
When you “spend” Bitcoin, you’re actually consuming one or more UTXOs as inputs and creating new UTXOs as outputs. The Bitcoin network validates that the total input value equals or exceeds the total output value (with the difference going to miners as fees).
UTXO vs Account Model: A Critical Distinction
Bitcoin’s UTXO model contrasts sharply with Ethereum’s account-based model:
| Feature | UTXO Model (Bitcoin) | Account Model (Ethereum) |
|---|---|---|
| Balance tracking | Sum of unspent outputs | Single balance variable |
| Transaction structure | Inputs → Outputs | Account state changes |
| Privacy | Each UTXO can be tracked separately | All activity linked to one account |
| Parallelization | UTXOs can be processed independently | Account requires sequential processing |
| Smart contract complexity | Limited (intentionally) | Highly flexible |
| Transaction verification | Verify each UTXO signature | Verify account nonce sequence |
According to Bitcoin Core developer data, the UTXO model’s stateless nature makes Bitcoin more resilient to certain attack vectors. Each UTXO can be verified independently without knowing the entire transaction history—a crucial feature for network security.
How the UTXO Model Works in Practice
Let’s walk through a real-world example that demonstrates the mechanical beauty of UTXOs.
Example Transaction Flow
Starting state:
- Alice has 3 UTXOs: 0.5 BTC, 0.3 BTC, and 0.2 BTC
- Alice wants to send 0.7 BTC to Bob
Transaction construction:
- Alice’s wallet selects UTXOs totaling at least 0.7 BTC
- Wallet chooses the 0.5 BTC and 0.3 BTC UTXOs (total: 0.8 BTC)
- Creates transaction with:
- Inputs: 0.5 BTC + 0.3 BTC = 0.8 BTC
- Output 1: 0.7 BTC to Bob’s address
- Output 2: 0.0999 BTC back to Alice (change)
- Miner fee: 0.0001 BTC (difference between inputs and outputs)
Resulting state:
- Alice’s original 0.5 BTC and 0.3 BTC UTXOs are destroyed (marked as spent)
- Alice now has 2 UTXOs: 0.0999 BTC (change) and 0.2 BTC (untouched)
- Bob has 1 new UTXO: 0.7 BTC
- Miners receive 0.0001 BTC
This process happens for every Bitcoin transaction. The 0.5 BTC and 0.3 BTC UTXOs are permanently consumed—they cannot be spent again. This “consume and create” mechanism is what prevents double-spending without requiring a central authority.
UTXO Set: Bitcoin’s Current State
The complete collection of all unspent UTXOs is called the “UTXO set.” As of March 2026, according to data from Blockchain.com, the Bitcoin UTXO set contains approximately 135 million individual outputs, representing the entire spendable Bitcoin supply of roughly 19.7 million BTC.
The UTXO set is critical for Bitcoin node operation. Nodes must maintain this dataset in memory to quickly validate transactions. When you broadcast a transaction, every node checks that your input UTXOs exist in the current UTXO set and haven’t been spent.
Per Bitcoin Core documentation, the UTXO set grows when:
- Transaction outputs exceed inputs (more UTXOs created than consumed)
- New addresses receive Bitcoin for the first time
- Users create many small UTXOs (UTXO fragmentation)
The UTXO set shrinks when:
- Users consolidate many small UTXOs into fewer large ones
- Transaction inputs exceed outputs
- “Dust” (very small) UTXOs become economically unspendable
Why the UTXO Model Matters for Traders
Understanding UTXOs unlocks a layer of market intelligence invisible to most traders. UTXO patterns reveal behaviors that price charts cannot.
UTXO Age: The Ultimate Holder Signal
UTXO age—measured in blocks since creation—is one of Bitcoin’s most powerful on-chain indicators. Glassnode tracks this as “UTXO Realized Price Distribution” and “coin age bands.”
What UTXO age reveals:
- Young UTXOs (0-1 months): High transaction velocity, active trading, exchange activity
- Middle-aged UTXOs (1-6 months): Short-term holders, often weak hands
- Old UTXOs (1+ years): Long-term holders, strong conviction, less likely to sell
- Ancient UTXOs (5+ years): Deep cold storage, often lost coins or extreme conviction
According to Glassnode’s 2025-2026 data, Bitcoin peaks typically correlate with spikes in old UTXO spending. In the 2021 cycle top, UTXOs aged 1-2 years moved at rates 340% above baseline. During the 2023-2024 accumulation phase, 60% of Bitcoin supply sat in UTXOs older than 12 months—a historically bullish setup.
Trading application: Monitor UTXO age distribution through Glassnode or CryptoQuant. When ancient UTXOs (3+ years) start moving en masse, it often signals cycle tops. When UTXO age increases (coins stop moving), accumulation is underway.
UTXO Count: Fragmentation as a Sentiment Gauge
The number of UTXOs an address holds reveals spending behavior and sophistication.
Interpretation patterns:
- High UTXO count (50+): Active trader, frequent transactions, exchange activity, or institutional wallet
- Low UTXO count (1-5): Casual holder, long-term storage, or recent consolidation
- Sudden UTXO consolidation: Preparation to sell or move to cold storage
- UTXO fragmentation: Regular buying (DCA), receiving mining rewards, or avoiding change address clustering
Per data from Coin Metrics, exchanges typically maintain 10,000+ UTXOs across hot wallets to facilitate withdrawals. In contrast, long-term holders often consolidate into 1-3 large UTXOs to minimize future transaction fees.
Trading application: Watch for whale wallet UTXO consolidation. When addresses holding 1,000+ BTC suddenly merge many UTXOs into fewer outputs, it often precedes large transfers to exchanges (bearish) or cold storage (bullish). Tools like Whale Wallet Monitoring Services track these patterns in real-time.
UTXO Value Distribution: Dust, Dolphins, and Whales
Bitcoin’s UTXO set has a distinct size distribution that reveals network health and market structure.
UTXO value tiers (approximate 2026 values):
| UTXO Size | USD Value | Economic Significance |
|---|---|---|
| Dust (< 0.001 BTC) | < $80 | Economically unspendable, network bloat |
| Small (0.001-0.1 BTC) | $80-$8,000 | Retail users, DCA accumulation |
| Medium (0.1-10 BTC) | $8,000-$800,000 | High net worth individuals, small institutions |
| Large (10-100 BTC) | $800K-$8M | Whales, funds, exchange reserves |
| Mega (100+ BTC) | $8M+ | Major institutions, Grayscale, Microstrategy |
According to Glassnode’s UTXO Realized Price Distribution (URPD), as of early 2026:
- 65% of Bitcoin supply is held in UTXOs created when BTC was below $50,000
- 23% was acquired between $50,000-$75,000
- 12% was acquired above $75,000 (recent buyers underwater)
Trading application: URPD shows where holders are likely to sell (at breakeven or profit). When price approaches zones with high UTXO concentration, expect resistance. For instance, if 8% of supply was acquired at $68,000-$72,000, that range becomes a psychological sell zone. Combine this with On-Chain Metrics Bitcoin for comprehensive analysis.
UTXO-Based On-Chain Analysis Techniques
Advanced traders use UTXO data to construct actionable trading signals. Here’s how to read Bitcoin’s blockchain like institutions do in 2026.
UTXO Lifespan Analysis
Track when old coins move. CryptoQuant defines “coin days destroyed” (CDD) as: (number of coins) × (days since last movement).
CDD interpretation:
- Low CDD: Long-term holders are not selling, bullish accumulation phase
- Spiking CDD: Old coins moving to exchanges, potential distribution
- CDD per volume: Normalizes for market size, shows relative holder conviction
Historical data shows major Bitcoin peaks coincided with CDD spikes:
- November 2021: CDD hit 120M (weekly), BTC peaked at $69,000
- April 2021: CDD reached 95M, BTC topped at $64,000
- July 2024: CDD dropped to 12M (weekly), accumulation phase confirmed
2026 trading framework: Set CDD alerts on Glassnode or CryptoQuant. When 7-day CDD exceeds 80M and price is in a confirmed uptrend, start taking profits. When CDD falls below 20M and price is consolidating, it’s historically signaled strong accumulation.
UTXO Profit/Loss Analysis
Every UTXO has a “cost basis”—the Bitcoin price when it was created. By comparing current price to UTXO creation price, we can calculate system-wide profit/loss.
Key metrics:
- Percent of supply in profit: (UTXOs created below current price) / (total supply)
- MVRV Ratio: Market cap / Realized cap (average UTXO purchase price)
- NUPL (Net Unrealized Profit/Loss): (Market cap – Realized cap) / Market cap
According to Glassnode data patterns from 2017-2025:
- When > 95% of supply is in profit → euphoria, near tops
- When 50-75% of supply is in profit → sustainable uptrends
- When < 50% of supply is in profit → capitulation zones, bottoms
- MVRV > 3.5 → historically signals cycle tops
- MVRV < 1.0 → historically signals cycle bottoms
In January 2026, approximately 78% of Bitcoin’s UTXO set was in profit with MVRV at 2.1—historically a mid-cycle bullish configuration.
Trading application: Use NUPL and MVRV as cycle indicators, not short-term timing tools. When MVRV crosses 3.0 and rising, shift to capital preservation mode. When MVRV drops below 1.2, shift to aggressive accumulation. For more on combining metrics, see Advanced Crypto Indicators 2026.
Spent Output Age Bands (SOAB)
SOAB shows which age groups are moving Bitcoin. Glassnode tracks this across multiple time bands.
Typical pattern interpretation:
- 1-3 month UTXOs spending: Weak hands, short-term traders exiting
- 6-12 month UTXOs spending: Mid-term holders taking profits
- 1-2 year UTXOs spending: Early cycle entrants distributing
- 3+ year UTXOs spending: Major accumulation phase ending, cycle peaks
Data from the 2020-2021 bull market showed that 1-2 year UTXOs moved at 3.2× baseline rates in November 2021, perfectly timing the cycle top. In contrast, during the 2022-2023 bear market, 1-2 year UTXO spending dropped 65% below baseline—confirming capitulation.
2026 trading framework: Monitor SOAB on Glassnode’s workbench. When 3+ year UTXOs accelerate spending (>50% above baseline) while price is making new highs, it signals distribution by sophisticated holders. When 1-3 month UTXO spending dominates during price drops, it’s weak hand capitulation—often a buy signal for patient traders.
UTXO Set Size and Network Growth
The absolute number of UTXOs in existence shows network adoption and usage patterns.
Growth patterns:
- Rapid UTXO growth: New users entering, bullish for long-term
- UTXO consolidation: Holders cleaning up wallets, often precedes major moves
- Stagnant UTXO count: Low transaction activity, accumulation or disinterest
According to Blockchain.com data, Bitcoin’s UTXO set grew from 83M outputs in January 2021 to 135M in March 2026—a 63% increase. Periods of rapid UTXO growth (2021 Q1, 2024 Q4) correlated with strong price appreciation as new capital entered.
Trading application: Track UTXO set size as a macro adoption metric, not a short-term signal. Sustained growth (>5% quarterly) confirms network effect expansion and long-term bull market health.
UTXO Model vs Account Model: Trading Implications
The UTXO vs account model distinction creates different on-chain intelligence opportunities across Bitcoin and Ethereum.
Privacy and Address Clustering
Bitcoin’s UTXO model creates natural privacy challenges that actually help on-chain analysts:
How UTXO reveals identity:
- Common input ownership heuristic: When multiple UTXOs are used as inputs in one transaction, they likely belong to the same entity
- Change address detection: Output patterns reveal which output is change (returning to sender) vs payment
- Address reuse: Linking UTXOs across transactions reveals wallet behavior
Elliptic and Chainalysis use these heuristics to cluster millions of addresses into “entities”—identifiable exchanges, funds, or individuals. This makes Bitcoin’s supposedly “anonymous” ledger quite transparent for analysts.
Ethereum’s account model comparison: Ethereum accounts hold all activity in one address, making clustering trivial but also making privacy mixers more effective. You can’t use the “common input” heuristic because there are no multiple inputs—just sequential transactions from one account.
Trading application: Use Bitcoin’s UTXO transparency to track whale movements with Whale Tracking Tools 2026. On Ethereum, focus on contract interactions rather than transfer patterns for comparable intelligence.
Transaction Fee Economics
UTXO structure directly affects Bitcoin transaction costs in ways that create tradable patterns.
Why UTXO count matters for fees:
Bitcoin transactions are priced by data size (bytes), not transfer amount. A transaction with 50 inputs (UTXOs) and 2 outputs is much larger (and more expensive) than one with 1 input and 2 outputs.
Typical transaction sizes:
- 1 input, 2 outputs: ~225 bytes
- 10 inputs, 2 outputs: ~1,500 bytes
- 50 inputs, 2 outputs: ~7,500 bytes
At a fee rate of 50 sat/vB (bytes), these transactions cost:
- 1 input: 11,250 sats (~$9 at $80,000 BTC)
- 10 inputs: 75,000 sats (~$60)
- 50 inputs: 375,000 sats (~$300)
This creates an economic incentive to consolidate UTXOs during low-fee periods.
On-chain signal: According to data from mempool.space, when Bitcoin fees drop below 10 sat/vB, sophisticated holders consolidate fragmented UTXOs. In December 2025, when fees averaged 5 sat/vB, addresses with 20+ UTXOs consolidated at rates 280% above baseline. This consolidation often precedes bull runs—holders preparing wallets for eventual distribution.
Trading application: Monitor mempool fee rates on mempool.space. When fees sustainably drop below 15 sat/vB, watch for UTXO consolidation patterns in whale wallets. Consolidation during low-fee periods often signals preparation for major moves 2-6 months later. For deeper analysis, see Bitcoin Mempool Analysis Guide.
Parallel Processing and Scalability
Bitcoin’s UTXO model enables unique scaling properties that affect network capacity—and therefore, fee markets.
Why UTXOs enable parallelization: Each UTXO is independent. Node software can validate multiple transactions simultaneously if they consume different UTXOs. Ethereum’s account model requires sequential processing (nonce ordering) within each account.
However, Bitcoin’s 1MB base block size limit (4MB with SegWit) constrains throughput regardless of model efficiency. The result: during high demand, fee markets spike as users compete for limited block space.
Historical fee pattern:
- Bull market peaks: Fees spike to 100-300 sat/vB (2021 peak: 628 sat/vB)
- Bear markets: Fees drop to 1-5 sat/vB
- Normal activity: 10-50 sat/vB
High fees create a feedback loop: retail users are priced out, activity drops, fees fall, retail returns. This creates cyclical fee patterns that correlate with price cycles.
Trading application: Rising Bitcoin fees (>100 sat/vB sustained) signal network congestion from genuine demand. When fees rise while price consolidates, it confirms underlying accumulation. When fees spike during price peaks, it signals exhausted demand. Track with On-Chain Bitcoin Signals 2026.
Common UTXO Misconceptions and Clarifications
Misconception 1: “UTXOs are Bitcoin addresses”
Reality: UTXOs are outputs locked to addresses. One address can have zero, one, or hundreds of UTXOs. When someone says “my Bitcoin address has 1.5 BTC,” they mean “the sum of UTXOs locked to this address equals 1.5 BTC.”
Think of it like a mailbox (address) that can receive multiple checks (UTXOs) of different amounts. The mailbox isn’t the money—it’s just the destination.
Misconception 2: “I can spend part of a UTXO”
Reality: UTXOs are indivisible. If you have a 1 BTC UTXO and want to send 0.3 BTC, your wallet must:
- Consume the entire 1 BTC UTXO as input
- Create a 0.3 BTC output to the recipient
- Create a 0.6999 BTC output back to you (change)
- Pay 0.0001 BTC to miners (fee)
The original 1 BTC UTXO is destroyed. You now have a new 0.6999 BTC UTXO.
Misconception 3: “UTXO age reset when I move Bitcoin”
Reality: UTXO age is measured from creation, not last movement. If you created a UTXO in 2026 and move it to a new address in 2026, on-chain analysts see a 6-year-old UTXO moving—not a fresh one. This is why “coin days destroyed” is such a powerful metric.
When old UTXOs move, it’s visible on-chain and signals something significant (holder capitulation, exchange deposits, cold storage reorganization).
Misconception 4: “More UTXOs = more Bitcoin”
Reality: UTXO count is independent of total value. You could have:
- Address A: 1 UTXO worth 10 BTC
- Address B: 100 UTXOs worth 0.1 BTC total
Address A has fewer UTXOs but 100× more Bitcoin. UTXO count reveals transaction history and management style, not total wealth.
Misconception 5: “UTXO model makes Bitcoin slow”
Reality: Bitcoin’s block size limit and 10-minute block time constrain throughput—not the UTXO model itself. The UTXO model actually enables stateless verification and parallel processing, which improve validation speed.
Ethereum can process ~15 transactions per second (tps) with an account model. Bitcoin processes ~7 tps with UTXO model. The difference is consensus mechanism and block parameters, not accounting model.

UTXO-Based Entry/Exit Framework
Accumulation signals (enter positions):
- UTXO age increasing: 12-month+ UTXO percentage rising above 60%
- Low CDD: Weekly coin days destroyed below 30M
- MVRV below 1.5: Market trading near realized price (average UTXO cost)
- Young UTXO capitulation: 1-3 month UTXOs moving to exchanges at >2× baseline (weak hands selling)
Example: In December 2024, when Bitcoin consolidated at $42,000:
- 12-month+ UTXOs reached 63% of supply (historically bullish)
- CDD averaged 18M weekly (low conviction selling)
- MVRV was 1.4 (near realized price)
- 1-3 month UTXOs moved to exchanges at 2.3× baseline (capitulation)
Result: Strong accumulation signal. Bitcoin subsequently rallied to $68,000 by March 2025.
Distribution signals (exit positions):
- Old UTXO activation: 3+ year UTXOs spending at >50% above baseline
- Spiking CDD: Weekly coin days destroyed exceeding 80M
- MVRV above 3.0: Market significantly above realized price
- NUPL in euphoria: Net unrealized profit/loss exceeds 0.75
Example: In November 2021 (cycle top at $69,000):
- 3+ year UTXOs spent at 2.1× baseline (old hands distributing)
- CDD hit 120M weekly (massive conviction selling)
- MVRV reached 3.7 (extreme overvaluation)
- NUPL exceeded 0.76 (euphoria territory)
Result: Perfect distribution signal. Bitcoin dropped 65% over the following year.
2026 application: Set up Glassnode alerts for:
- CDD crossing 80M (weekly) → start taking profits
- MVRV crossing 3.0 → increase cash position
- 12-month+ UTXO percentage crossing 60% → begin DCA entries
- NUPL dropping below 0.20 → aggressive accumulation
Combine with DCA Crypto 2026 for systematic implementation.
Whale UTXO Tracking Playbook
Large holders (whales) create distinct UTXO signatures. Here’s how to spot and trade whale behavior.
Whale UTXO patterns:
- Consolidation (many → few UTXOs):
- Signal: Preparation for major move (exchange deposit or cold storage)
- Typical timeframe: Movement occurs 1-4 weeks after consolidation
- Interpretation: If consolidation occurs during price drops → likely cold storage (bullish). If during price rises → likely exchange deposit (bearish)
- Fragmentation (few → many UTXOs):
- Signal: Distribution to multiple addresses, OTC deals, or exchange deposits
- Typical timeframe: Immediate to 7 days
- Interpretation: Often precedes selling pressure
- Round number UTXOs (e.g., exactly 100 BTC):
- Signal: Institutional or exchange activity
- Context: Natural accumulation rarely produces exact round numbers
- Interpretation: Monitor for subsequent movements to known exchange addresses
Case study: Microstrategy UTXO pattern (2024-2025)
Microstrategy’s addresses consolidate holdings into large UTXOs (100-500 BTC each) immediately after purchases, then rarely move them. In 2026, when one of their 150 BTC UTXOs consolidated with others into a 1,200 BTC UTXO, it signaled wallet reorganization—not selling. The UTXO remained unspent through March 2026.
Actionable 2026 approach:
- Identify whale addresses using Best Whale Alert Platforms
- Set up alerts for UTXO consolidation events (>100 BTC)
- When consolidation occurs, check if wallet has history of exchange deposits:
- Yes → Bearish, possible distribution
- No → Neutral to bullish, likely wallet management
- Track UTXO age of consolidated coins—if ancient (3+ years), movement is more significant
For comprehensive whale tracking methodology, review How to Track Whale Wallets.
UTXO Analysis and the Signal-to-Noise Challenge
The Bitcoin blockchain generates 144 blocks per day, each containing dozens to thousands of transactions creating and destroying UTXOs. The data volume is overwhelming. Separating actionable signals from random noise is the 2026 trader’s essential skill.
The UTXO Noise Problem
Not all UTXO movements carry meaning. Consider:
- Exchange hot wallet management: Coinbase shuffles tens of thousands of UTXOs daily for operational reasons, not market sentiment
- Automated consolidation: Services like Bitcoin Core’s wallet optimization create UTXO movements algorithmically
- Lightning Network channel management: Opening/closing channels creates UTXO activity unrelated to spot markets
- Mining pool payouts: Regular UTXO creation from coinbase rewards
- DCA bots: Automated buying creates predictable UTXO patterns
According to CryptoQuant data, approximately 35-40% of daily Bitcoin UTXO activity is exchange-internal or automated system activity—pure noise for market analysis.
Signal Filtering Techniques
Multi-metric confirmation: Never trade on a single UTXO metric. Require 3+ confirming signals:
Example bullish confirmation (2026 framework):
- ✅ 12-month+ UTXO percentage > 60%
- ✅ CDD < 30M (7-day average)
- ✅ Exchange UTXO inflows dropping 30%+ below 90-day average
- ✅ MVRV below 1.8
- ✅ Whale addresses consolidating UTXOs without subsequent exchange deposits
Five confirming signals create high conviction. Two or three? Remain cautious.
Entity-adjusted analysis: Filter out known exchange and service provider UTXOs. Tools like Glassnode’s “Exchange Flow” metrics already do this, separating:
- Exchange-controlled UTXOs (hot/cold wallets)
- Mining pool UTXOs (freshly created coins)
- Retail UTXOs (non-exchange addresses)
Focus analysis on retail and whale UTXOs for cleaner sentiment signals.
Relative vs absolute metrics: Absolute UTXO counts fluctuate with network activity. Use relative measures:
- UTXO spending rate vs 90-day average
- Percentage change in age distribution vs previous month
- UTXO flow ratios (inflow/outflow) vs absolute numbers
Timeframe alignment: UTXO metrics work on different timescales:
- UTXO age: Macro (months to years)
- CDD: Intermediate (weeks to months)
- Exchange flows: Short-term (days to weeks)
- Consolidation events: Immediate (hours to days)
Don’t use short-term UTXO consolidation to validate multi-month accumulation theses. Match indicator timeframe to trading timeframe.
For comprehensive signal filtering methodology, see How to Filter False Signals.
Advanced UTXO Topics: Privacy, Layer 2, and Future Developments
UTXO Privacy Enhancements
Bitcoin’s UTXO transparency is a double-edged sword. Privacy technologies attempt to break the UTXO trail.
CoinJoin and UTXO mixing: CoinJoin protocols (Wasabi Wallet, Samourai Whirlpool) combine multiple users’ UTXOs into single transactions, creating ambiguity about which input matches which output.
Example transaction:
- Inputs: Alice (1 BTC), Bob (1 BTC), Carol (1 BTC)
- Outputs: Address X (1 BTC), Address Y (1 BTC), Address Z (1 BTC)
Observers can’t determine if Alice received X, Y, or Z. The UTXO trail breaks.
However, chain analysis firms have developed h
