Request: Hide the balance

[2bEichhornchen]

**Feature Request
Hiding the balance

Describe the solution you'd like
I would like the balance to be hidden when I open the wallet just like the android.

Describe alternatives you've considered
I would like the balance to be displayed as "Hidden Mode" until I tap it.

Additional context
When I want to pay with Zap, the receiver is staring at my screen to see if the transactions go smoothly.
Then, my total balance is helplessly exposed to the others. Please make this feature to be available sooner.
