how to solve the problem of gold and defense disappearing from the hero when their values are high?

You can easily solve the gold problem by monitoring the counter and, when it starts to reset (before that day), exchanging a lot of gold for other resources – crystals, dragon stones, sulfur, mercury, etc. – to reduce the counter slightly so it doesn't reset to zero. This is better than simply having 0.

As for defense, I don't know.
