Again..can people not think beyond what's in front of their faces? Merchants SAVE MONEY..
However, consumers get more from credit cards than just a payment instrument: things like short-term credit, safety against card loss or theft, cancellation of payment if merchant defaults... And good merchants know that "the client is always right".
what do you think will happen when merchants and their competitors both accept something that saves them money over cc's. Err.umm discounts.
It has been decades since the last time I saw a merchant offering discount to clients who pay in cash rather than CC. I wonder why they don't do it. (Greater risk of robbery or theft? Pressure from CC companies?) But, whatever the reason, it will probably apply to bitcoin, too.
