DeFiSheets - Crypto spreadsheet tools. Buy once. No subscriptions.

Hey Product Hunt 👋 I got tired of paying $200/year for crypto tax software that sees my wallet addresses and sells my data to "partners." So I built four Google Sheets templates that do everything those SaaS products do — for a single one-time purchase. Why spreadsheets? • Your data stays in YOUR Google Drive • No monthly bills • Full control — edit anything • You own the file forever The four tools: 1. Crypto Portfolio & Tax Tracker (FIFO engine included) 2. Day Trading Journal (long/short P&L, win rate) 3. DeFi Yield Dashboard (multi-protocol, IL calculator) 4. NFT Portfolio & Rarity Tracker Launch week: 50% off with code LAUNCH50 Would love honest feedback. What's missing? What should I build next? Roast me if needed 🔥
