Tracking Crypto Portfolio

Overview

This skill provides comprehensive cryptocurrency portfolio tracking with:

• Real-Time Valuations: Current prices from CoinGecko
• Holdings Breakdown: Quantity, value, and allocation per asset
• P&L Tracking: Unrealized gains/losses with cost basis
• Allocation Analysis: Category breakdown and concentration flags
• Multiple Export Formats: Table, JSON, CSV

Key Capabilities:

• Track holdings across multiple assets
• Calculate portfolio total value in USD
• Identify overweight positions (concentration risk)
• Export for analysis tools and tax reporting

Prerequisites

Before using this skill, ensure:

1. Python 3.8+ is installed
2. requests library is available: pip install requests
3. Internet connectivity for CoinGecko API access
4. A portfolio JSON file with your holdings

Portfolio File Format

Create a portfolio file (e.g., holdings.json):

Copy{
  "name": "My Portfolio",
  "holdings": [
    {"coin": "BTC", "quantity": 0.5, "cost_basis": 25000},
    {"coin": "ETH", "quantity": 10, "cost_basis": 2000},
    {"coin": "SOL", "quantity": 100}
  ]
}

Fields:

• coin: Symbol (BTC, ETH, etc.) - required
• quantity: Amount held - required
• cost_basis: Average purchase price per coin (optional, for P&L)
• acquired: Date acquired (optional, for records)

Instructions

Step 1: Assess User Intent

Determine what portfolio information the user needs:

• Quick check: Total value and top holdings
• Holdings list: Full breakdown of all positions
• Detailed analysis: Allocations, P&L, risk flags
• Export: JSON or CSV for external tools

Step 2: Execute Portfolio Tracking

Run the tracker with appropriate options:

Copy# Quick portfolio summary
python {baseDir}/scripts/portfolio_tracker.py --portfolio holdings.json

# Full holdings breakdown
python {baseDir}/scripts/portfolio_tracker.py --portfolio holdings.json --holdings

# Detailed analysis with P&L and allocations
python {baseDir}/scripts/portfolio_tracker.py --portfolio holdings.json --detailed

# Export to JSON
python {baseDir}/scripts/portfolio_tracker.py --portfolio holdings.json --format json --output portfolio_export.json

# Export to CSV
python {baseDir}/scripts/portfolio_tracker.py --portfolio holdings.json --format csv --output portfolio.csv

Step 3: Present Results

Format and explain the portfolio data:

• Show total portfolio value prominently
• Highlight 24h and 7d changes
• Explain allocation percentages
• Flag any concentration risks
• For detailed mode, explain P&L calculations

Command-Line Options

Allocation Thresholds

By default, positions > 25% allocation are flagged:
