It's either you might have the wrong market for your product or you have promoted it badly. I myself is staying in a country in South East Asia but for once I have never seen any promotions regarding X infinity market not until now. Also if you want to test out your product which I think is a great idea you should have some recruitment process on some volunteers to see if their life was made easier with the use of your debit card linked to their cryptocurrency. Usually a product like what you have is afraid to be tested first by them if they are not seeing any good reputation behind yours, having a good feedback as well as partnering up with reputable banks is the best way to build their trust.
