Hey Product Hunt 👋 Maker here. Quick backstory on why this exists: I blew up two crypto trading accounts. ~$5,500 gone. Both times the problem wasn't strategy — I had no idea how big my positions should be relative to my account size. I'd "feel" a trade, throw 10-15% of my account at it, and one bad call would wipe me out. Every existing free calculator I found was either behind an email gate, riddled with affiliate ads, or wrapped in a "$300 trading course" upsell. Just to calculate a position size. So I built my own. Then realized I needed a few more tools. Then a few more. Now there are 10. What's included: 📐 Position Size Calculator 🎯 TP/SL Calculator with R:R ratio 💰 Profit Calculator (with exchange fees) 📈 DCA Calculator (real historical data — "what if $50/week into BTC since 2018?" type questions) 🌱 Staking Calculator (compound vs simple) 🔄 Crypto Converter (30+ fiat currencies) 📊 Live Prices for top 100 coins ⏱ Bitcoin Halving Countdown 🔍 RSI Screener 📘 How to Buy Bitcoin (beginner guide) All free. No signup. No email gate. No "premium tier" coming later. Available in 5 languages (EN/RU/ZH/ES/AR). Tech stack for the curious: - 100% static HTML/JS hosted on Cloudflare Pages (free tier) - Binance + CoinGecko APIs called directly from browser - No backend, no database, no servers to maintain - Python build system generates 100 pages from data files - Costs me $0/month to run The only "monetization": two affiliate links to Bybit and OKX (the exchanges I actually use). If it pays for itself eventually, great. If not, also fine — was built because I needed it. Looking for: - Bug reports - UX feedback (especially mobile) - What calculator should I build next? - Honest critiques Thanks for checking it out 🙏
