Ideation
A good way to earn money is to save on irreducible every day expenses such as food, groceries, consumer goods, etc.
This is what we set out to do with Ethconomy.io, a platform that allows you to cover everyday expenses using crypto at a discount.
For example, you can purchase Amazon gift cards with up to 30% discount, which can then be used to buy groceries, food deliveries, consumer products, and giftcards to other stores/services.
The idea of "saving" money here isn't really good. If you will just spend something in order to save that 30% for something in order to buy those basic needs then you aren't saving at all you are just spending more on unnecessary things just to get that discounts. The 30% "saved" on something when buying from your service should have been 100% if they had not bought anything from the service. I'm not ruining your idea but don't fool people that they are earning something when they are buying from you. The 30% discounts looks great if people are really looking for that bargain hunt but discounts, cashbacks, and rebates are a direct opposite for people who want to save money for their basic needs.
