Remember the Target credit card data hack?
Consumers aren't giving their payment info (credit card numbers) when paying with bitcoin, so it's impossible for any new charges to pop up after payment has been made.
Not really a benefit. As a consumer you're not responsible for fraudulent charges on your credit card.
Yes you are, it's called interest and annual fees. It's built in there. The fraud also gets passed on to the merchant, that raises prices again hurting YOU the consumer.
