I'm Alan, and I built Satoshi Daily — a free daily Bitcoin price prediction game. How it works: Every day, you get a target time (e.g. "tomorrow at 3:47pm UTC") You predict what Bitcoin's price will be at that exact moment If you're within $500 of the actual price, you share the $5 daily prize pool — paid in real BTC via Lightning ⚡ Why I built it: I wanted something that made Bitcoin fun and accessible without any risk. No deposits, no trading, no catch. Just one free guess per day (share with a friend to unlock a second). The stack (for the nerds): React + TypeScript PWA, Supabase (auth, Postgres, Edge Functions), a median-of-3 price oracle (CoinGecko, Binance, Coinbase), and Cloudflare Turnstile. Deployed on Netlify. What I'd love feedback on: Is the game loop compelling enough to come back daily? Any friction in the signup flow? Would you want features like weekly leaderboards or streak rewards? It's completely free and always will be. I'd love for you to try it and tell me what you think 🙏
