Hey Product Hunt! 👋 I built Coincat because I almost got wrecked by crypto taxes. In 2027, Korea will start taxing crypto gains at 22%. The problem? Most Korean investors have traded across 3-4 exchanges over the years, with thousands of transactions. Calculating cost basis manually is a nightmare. I spent weeks in Excel trying to figure out my own taxes. Matching buys to sells, tracking transfers between exchanges, converting timestamps... I realized if this was hard for me (a developer), regular investors would be completely lost. So I built what I wished existed: - Connect your exchanges in 30 seconds - See your entire portfolio in one place - Know exactly how much tax you'll owe - Find legal ways to reduce it We're starting with Korean exchanges, but planning to add Binance and other global exchanges soon. Would love your feedback! 🐱
