                Mail::to($user->email)->send(new ExpertNotificationMail($user, $expert, $request->input('amount')));
                \Log::info('Expert notification email sent to: ' . $user->email);
            }
        } catch (\Exception $e) {

## 🔐 Security & Error Handling

1. **Email Sending is Wrapped in Try-Catch:**
   - If email fails, it doesn't break the main transaction
   - Error is logged but success message still shows
   - User still gets confirmation they copied the trader

2. **Null Checks:**
   - Verifies expert exists in database
   - Verifies user has email address
   - Safe to run even if data is incomplete

3. **Logging:**
   - Successful sends logged to `storage/logs/laravel.log`
   - Errors logged with full exception message
   - Helps with troubleshooting
