JagSim - Free $100k paper trading simulator, stocks and crypto

I built JagSim because your first $100,000 shouldn't be real money. Most people lose in their first year learning with real cash on the line, so I wanted a place to make those expensive mistakes with virtual money and keep the lesson. It runs in the browser, uses real 15-minute delayed prices for stocks and crypto, gives you a persistent $100k portfolio that doesn't reset, a full order ticket (market, limit, stop, long and short), and a live leaderboard. There's a free demo you can try without an account. Would love your feedback on what would make it more useful.
