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.
That's the theory, the reality is that it is a major pain, a huge waste of your time, and sometimes expensive to deal with any kind of identity theft.
The other benefit is some degree of discounting that is likely at some point (maybe not right away).
Also, this assumes you even have credit card, or a bank account, and a lot of people don't.
The benefits are probably bigger and faster in less developed countries that both lack a well-functioning financial system and also have a greater dependence on remittence. There may be a leapfrog effect similar to how places without landlines adopted cell phones much faster than cell phones are replacing land lines elsewhere, a slow process that is still ongoing and will likely continue for another decade or two at least.
Only poor people don't have credit cards and bank accounts.
I could give a fuck about poor people and poor countries.
