The Zie app (website) offers two views so different types of users can focus on what matters most to them.
User view focuses on balances and transfers. It is designed for everyday usage where the user only needs to move value without tracking individual coins.
Collector view provides access to individual coins, their market value, and trading tools. It is designed for users who want to manage unique coins and optimize collection value.
If you want simple transfers, use user view. If you want to trade and collect unique coins, use collector view. You can switch views without losing any coins or balances, as both views are a visualization of the content of a pouch without altering it.
