The problem with this model that I think is that you pay the company for a card which enables you to get some cash back into the same card, the company itself currently is relying on the customers who don't use the card that much to pay off those customers who would use the card, This model would only work if the company is able to get some partnerships with E-com websites where the E-com websites issue cashback to the users if they pay through these cards and this cashback are converted by gosats into bitcoins, otherwise, company is just repaying the same money which they took from customers as one-time fee-generating no revenues for itself
This business model is very similar to the business model of Cred. Whoever is using credit cards, must have heard of it. Cred also relies on the customer's money but their major revenue aource is advertising. Usually these type of cashback platforms promotes various brands and get paid by those brands in return. The annual fees is definitely a source of revenue for them but not a major one.
One thing I am unsure about. As per law, no Indian company can issue debit or credit cards except banks. So if this company is issuing cards from Singapore, they are illegal in India. Not sure how they are operating for Indian brands!
Cred has no business model so far, they had negligible revenues until last year, moreover, if the companies are offering people discounts there is a pretty slim chance that they'll offer something to Cred too, as Cred isn't really helping them generate any traffic so far, lately CRED has been focusing on two products namely CRED RentPay and CRED Stash,
Rentpay allows you to automate your monthly rentals and other recurring expenses more like an ECS while CRED Stash allows you an instant line of credit something like the DHANI App, most of the revenues so far are just from Interest on the deposits of the large fundings that they have received due to their user base.
