Comments
The card trading market friction is brutal. Most collectors and traders manually hunt for price movements and arbitrage opportunities across multiple sites and forums, which eats hours and causes them to miss price windows. PolyTCG removes that entire overhead by aggregating 321k+ cards with real-time pricing, 24-hour movers, and arbitrage alerts in one place. The portfolio tracking also means traders can monitor collections without spreadsheets. For serious card investors especially, having one authoritative source for market intelligence fundamentally changes the game - you go from scattered research to focused, data-driven trading decisions.
The EU/US arbitrage finder is the real differentiator here - price trackers are everywhere, but surfacing cross-market spreads is what people actually pay for in sneaker/watch tools, and I haven't seen it done for TCGs. One question: how fresh is "daily" pricing during a new set drop? That's exactly when collectors need it and when most trackers lag. Median pricing over last-sale is the right call for thin markets, too.
PolyTCG has great potential! A few improvements could make it even better. I'd love to share my feedback and suggestions. Email: [email protected]
