Investment
What you keep for the love of it on one side, what you keep for its value on the other.

When you add an item, choose My collection or My investment. A filter shows one, the other or both, and an item moves from one to the other in one tap.

Profit
Purchase price, today's value and profit, line by line and in total, with a chart of the value.
Sealed
Sealed product is valued just like cards, with day-by-day history for every product.

No. It tracks the value of what you own, it doesn't give investment advice.
