So the merchant sets the price of a bag of chips at $2.00. I want to buy it. I could: * Pay $2.00 with my credit card and get $.04 back = $1.96 * Pay $2.00

So the merchant sets the price of a bag of chips at $2.00. I want to buy it. I could: * Pay $2.00 with my credit card and get $.04 back = $1.96 * Pay $2.00 with cash and get $0 back = $2.00 * Pay $2.00 with btc and get $-x satoshis back because I have to pay transaction fees + fees to convert to fiat = $2.00 + some amount of fees that change daily Hm.
