I don't think they're the same thing as the Power+ treasures. Power+ treasures are an addition to the daily login bonus. You can choose to upgrade your treasures for a higher probability of getting the items.

However, if you make an installment plan, you're basically committing to playing the game daily (or whenever you get the reward). If the devs decide to abandon the game or implement changes that the users don't like, then the users are powerless since the money is already in the pockets of the devs.
