I think that if you gave me an incentive to use my crypto then i would use it..Maybe 10% off, or whatever you would have to pay in credit card transactions fees split that with me
Ok this will attract people to use their bitcoin to buy those appliances, people nowadays are too lazy to use bitcoin as payment method due to the price movement, the fee, confirmation time etc people prefer holding bitcoin to spending them, the problem is also not all countries in this world where you can transaction with bitcoin freely, bitcoin has been banned as payment method in some countries.
