You are a seasoned financial technology consultant with extensive experience in the cryptocurrency market. You are advising a software development company that is creating a new cryptocurrency portfolio tracker application. Your task is to provide a comprehensive feature specification document to guide the development team. This document should outline all essential and desirable features for a successful and user-friendly cryptocurrency portfolio tracker. The target audience is both novice and experienced cryptocurrency investors. Goal: Create a detailed feature specification document for a cryptocurrency portfolio tracker application that meets the needs of a broad range of users, from beginners to advanced traders. Feature Specification Document Structure: 1. Core Functionality (Must-Have Features): * Portfolio Tracking: * Automatic import of transaction history from major exchanges (e.g., Binance, Coinbase, Kraken, KuCoin, [Exchange Name]). * Manual entry of transactions for unsupported exchanges or wallets. * Real-time tracking of cryptocurrency prices (using APIs from [Data Provider Name]). * Display of portfolio value in multiple fiat currencies (e.g., USD, EUR, GBP, [Fiat Currency]). * Calculation of profit/loss for each asset and the overall portfolio. * Support for tracking multiple portfolios (e.g., personal, trading, long-term). * Asset Information: * Detailed information on each cryptocurrency (e.g., description, website, market cap, circulating supply). * Integration with CoinMarketCap, CoinGecko, or similar data providers. * Display of price charts with various timeframes (e.g., 1 day, 1 week, 1 month, 1 year, all-time). * Transaction History: * Comprehensive transaction log with details (e.g., date, time, cryptocurrency, amount, price, fees). * Filtering and sorting options for transaction history. * Export of transaction history in CSV format. 2. Advanced Features (Highly Desirable): * Alerts and Notifications: * Price alerts (e.g., notify when Bitcoin reaches $[Price]). * Portfolio rebalancing alerts (e.g., notify when asset allocation deviates from target). * News and market updates related to held cryptocurrencies. * Tax Reporting: * Automated tax calculation based on transaction history. * Support for different tax methods (e.g., FIFO, LIFO, HIFO). * Integration with tax software (e.g., TurboTax, TaxAct, [Tax Software Name]). * Generation of tax reports in required formats. * Integration with Decentralized Finance (DeFi): * Tracking of assets held in DeFi protocols (e.g., staking rewards, yield farming). * Support for popular DeFi wallets (e.g., MetaMask, Trust Wallet, [Wallet Name]). * Automatic detection of DeFi transactions. * Portfolio Analysis: * Visualization of asset allocation (e.g., pie chart). * Performance analysis (e.g., Sharpe ratio, Sortino ratio). * Risk assessment (e.g., volatility, correlation). 3. User Interface (UI) and User Experience (UX) Considerations: * Intuitive and easy-to-navigate design. * Customizable dashboard with widgets. * Dark mode option. * Support for multiple languages (e.g., English, Spanish, French, [Language]). * Mobile app (iOS and Android) with feature parity. 4. Security Considerations: * Two-factor authentication (2FA). * Encryption of sensitive data. * Regular security audits. * Compliance with data privacy regulations (e.g., GDPR). Output Format: Present the feature specification document as a well-structured plain text document, following the headings and subheadings outlined above. Be comprehensive and provide clear, actionable details for each feature. Avoid jargon and explain concepts in a way that both technical and non-technical stakeholders can understand.
