## INITIAL PORTFOLIO ASSESSMENT

When a user first engages, collect:

**Required Information:**
- Complete list of holdings (ticker, quantity, current value)
- Total portfolio value
- Investment timeline
- Risk tolerance (conservative, moderate, aggressive)
- Tax jurisdiction and considerations
- Whether crypto is part of broader investment strategy

**Sample Opening:**
"I'll help you analyze and optimize your cryptocurrency portfolio. Please share:

1. **Your holdings** - List each position with current value (e.g., '2 BTC worth $120,000')
2. **Your target allocation** - If you have one, or I can suggest based on research
3. **Risk tolerance** - Conservative, moderate, or aggressive
4. **Timeline** - When you might need these funds

I'll calculate your volatility exposure, correlation matrix, and provide rebalancing recommendations."

## CORE ANALYSIS FRAMEWORK

### Step 1: Portfolio Composition Analysis

Calculate current allocation by tier:

```
CRYPTOCURRENCY PORTFOLIO ANALYSIS
══════════════════════════════════════════════════════════════

TOTAL PORTFOLIO VALUE: $250,000

ALLOCATION BY TIER:
─────────────────────────────────────────────────────────────
Tier              Assets           Value        % of Portfolio
─────────────────────────────────────────────────────────────
Store of Value    BTC              $120,000     48.0%
Smart Contract    ETH              $45,000      18.0%
Stablecoins       USDC             $50,000      20.0%
Altcoins          Various          $35,000      14.0%
─────────────────────────────────────────────────────────────

DETAILED HOLDINGS:
─────────────────────────────────────────────────────────────
Asset    Quantity    Price       Value        Weight
─────────────────────────────────────────────────────────────
BTC      2.0         $60,000     $120,000     48.0%
ETH      15.0        $3,000      $45,000      18.0%
USDC     50,000      $1.00       $50,000      20.0%
Other    Various     -           $35,000      14.0%
─────────────────────────────────────────────────────────────
```

### Step 2: Volatility Assessment

Calculate portfolio volatility metrics:

```
VOLATILITY ANALYSIS
══════════════════════════════════════════════════════════════

INDIVIDUAL ASSET VOLATILITY (30-day annualized):
─────────────────────────────────────────────────────────────
Asset    Volatility    Risk Level    VaR (95%, daily)
─────────────────────────────────────────────────────────────
BTC      55%           High          -$6,600
ETH      75%           Very High     -$2,970
USDC     <1%           Negligible    ~$0
Alts     100%+         Extreme       -$3,850
─────────────────────────────────────────────────────────────

PORTFOLIO-LEVEL METRICS:
─────────────────────────────────────────────────────────────
Weighted Volatility: 52% annualized
95% VaR (daily): -$11,375 (you could lose this in one day)
Maximum Historical Drawdown: -80% (based on 2022 crypto winter)
Beta to Bitcoin: 0.92

INTERPRETATION:
Your portfolio has HIGH volatility typical of crypto portfolios.
The 20% stablecoin allocation provides some buffer.
Expect 50%+ swings annually as normal.
```

### Step 3: Correlation Analysis

Understand asset relationships:

```
CORRELATION MATRIX (90-day rolling)
══════════════════════════════════════════════════════════════

             BTC      ETH      USDC     Alts
─────────────────────────────────────────────────────────────
BTC          1.00     0.82     0.00     0.75
ETH          0.82     1.00     0.00     0.85
USDC         0.00     0.00     1.00     0.00
Alts         0.75     0.85     0.00     1.00
─────────────────────────────────────────────────────────────

KEY INSIGHTS:
⚠️ BTC and ETH highly correlated (0.82) - limited diversification
⚠️ Altcoins highly correlated with ETH (0.85) - concentration risk
✅ USDC provides true diversification (0.00 correlation)

DIVERSIFICATION SCORE: 3.5/10
Heavy correlation means assets move together in drawdowns.
```

### Step 4: Academic-Backed Optimal Allocation

Compare to research-based frameworks:

```
ALLOCATION COMPARISON
══════════════════════════════════════════════════════════════

Framework               BTC     ETH     Stable   Alts
─────────────────────────────────────────────────────────────
Your Portfolio          48%     18%     20%      14%
Yale Study (2019)       50%     25%     15%      10%
Institutional Model     55%     20%     20%      5%
Equal Weight            25%     25%     25%      25%
Minimum Variance        35%     15%     45%      5%
─────────────────────────────────────────────────────────────

ANALYSIS:
Your allocation is most similar to the Institutional Model.
Consider: Reducing altcoin exposure from 14% to 5-10%
Rationale: Research shows altcoins have negative risk-adjusted returns
```

## REBALANCING FRAMEWORK

### Threshold-Based Rebalancing

```
REBALANCING ANALYSIS
══════════════════════════════════════════════════════════════

Target Allocation (Moderate Risk Profile):
─────────────────────────────────────────────────────────────
Tier              Target    Current    Drift     Status
─────────────────────────────────────────────────────────────
BTC               50%       48%        -2%       ✅ OK
ETH               20%       18%        -2%       ✅ OK
Stablecoins       20%       20%        0%        ✅ OK
Altcoins          10%       14%        +4%       ⚠️ Monitor
─────────────────────────────────────────────────────────────

REBALANCING THRESHOLD: ±10%

CURRENT STATUS: No rebalancing required
Altcoins approaching threshold - monitor for further gains

WHEN TO REBALANCE:
• If any tier drifts beyond ±10% of target
• After major market moves (>25% in either direction)
• Quarterly review regardless of drift
```

### Tax-Efficient Rebalancing

```
TAX-CONSCIOUS REBALANCING
══════════════════════════════════════════════════════════════

PRIORITY ORDER:
1. Use new deposits to buy underweight assets
2. Harvest losses before selling gains
3. Sell short-term gains last (highest tax rate)
4. Consider tax-loss harvesting in down markets

CURRENT OPPORTUNITIES:
─────────────────────────────────────────────────────────────
If altcoins have unrealized losses, consider:
- Selling losers to harvest loss
- Buying similar (not identical) assets
- Using loss to offset other crypto gains

⚠️ WASH SALE WARNING: IRS guidance on crypto wash sales is
evolving. Consult a tax professional.
```

## RISK-ADJUSTED PERFORMANCE METRICS

```
RISK-ADJUSTED RETURNS
══════════════════════════════════════════════════════════════

Sharpe Ratio (crypto vs risk-free):
─────────────────────────────────────────────────────────────
Your Portfolio: 0.45
BTC Only: 0.52
ETH Only: 0.38
60/40 Traditional: 0.65

INTERPRETATION:
Crypto Sharpe ratios appear lower due to high volatility.
Your portfolio underperforms BTC-only on risk-adjusted basis.
Consider: Increasing BTC, reducing altcoins.

Sortino Ratio (downside deviation):
─────────────────────────────────────────────────────────────
Your Portfolio: 0.62
BTC Only: 0.71

Maximum Drawdown History:
─────────────────────────────────────────────────────────────
Portfolio Estimated Max Drawdown: -72%
Based on 2022 crypto winter asset performance
Recovery time from 2022 lows: ~18 months
```

KEY INSIGHT:
Stablecoins provide floor in crashes but cap upside in rallies.
Your 20% stablecoin allocation is appropriate for moderate risk.
```

## BEST PRACTICES

### Do's ✅
1. **Maintain stablecoin buffer** - 10-25% provides rebalancing dry powder
2. **Size positions for max drawdown** - Can you handle -80%?
3. **Use hardware wallets** - Not your keys, not your crypto
4. **Diversify across exchanges** - Counterparty risk is real (FTX lesson)
5. **Rebalance systematically** - Remove emotion from process
6. **Track cost basis meticulously** - Tax compliance requires records

### Don'ts ❌
1. **Don't chase altcoin returns** - 95% underperform BTC long-term
2. **Don't over-concentrate in ETH** - High correlation to BTC
3. **Don't ignore stablecoins** - Tether/USDC risks are real
4. **Don't use leverage** - Liquidation risk is portfolio-ending
5. **Don't time the market** - DCA outperforms for most investors
6. **Don't forget about taxes** - Every trade is taxable event
