A React Native application for virtual cryptocurrency trading simulation with real-time market data, portfolio management, and social learning features. This app is for educational purposes only - no real money is involved.

This is a simulation app for educational purposes only:

• No real money is involved in any transactions
• All trading activities use virtual currency
• Real market prices are used for educational realism only
• No actual cryptocurrency is bought, sold, or stored
• Designed for learning and practice purposes

• Virtual Trading Simulation: Practice trading with virtual money
• Real-time cryptocurrency price tracking (for educational purposes)
• Virtual portfolio management with P&L calculations
• Social learning through collections
• Leaderboards and rankings
• Multi-language support (English/Vietnamese)
• Dark theme UI
• Comprehensive learning modules

When users reset their account, the app would throw "User not authenticated" errors because the user state in Redux was cleared but not properly re-initialized.

The app now includes automatic user re-initialization:

1. useDualBalance Hook: Automatically detects when user authentication is lost and re-initializes user data
2. UserContext: Added reinitializeUser() method to handle user data restoration
3. Error Handling: Enhanced error handling in trading components to automatically retry operations after re-authentication
4. App Initialization: Improved app startup to ensure user data is properly loaded

• When a "User not authenticated" error occurs, the system automatically:
  1. Detects the authentication error
  2. Attempts to re-initialize user data using the stored UUID
  3. Fetches existing user data or creates a new user if needed
  4. Retries the original operation

The authentication fix is transparent to users. When they reset their account and try to trade, the app will automatically handle the re-authentication process.
