I have a question about buying things in stores with Bitcoin. Won't this(buying things with Bitcoin) make the price of items cost more? I mean for instance, if you are buying something that costs $50 and you have to transfer the worth in Bitcoin with a charge of maybe $0.50 which makes the items cost more unlike buying with cash. Is something being done to prevent this? Because it will discourage people from buying things with Bitcoin if the charges are being considered by users.
