Credit card fraud is a problem for credit card companies, but as a user I couldn't care less. The last time someone copied my credit card I've got a call from Amex within a few days, they reversed the transactions and sent me a new card.

Of course Bitcoin would be more secure (I own some myself). But from a users point of view this additional security doesn't really matter too much. I rather pay with my credit card and get 1% cashback.
