What the heck are you talking about, ive been getting all these benefits "for free". I have never paid a dime to any credit card company. No annual fees, no charges, nothing... I have all the above "totally free". If you have never heard about these things you should do some research.
You absolutely have, you just aren't aware of it. Merchants are charged fees by the CC processors and those are passed onto you, the customer. Don't think you're not paying for that shit one way or another just because you don't see the charge first hand.
Not only will merchants begin to offer bitcoin discounts because of the lower overhead compared to cc's but as A. Antonopoulus explains once the rising (deflationary) value of bitcoin is recognized by merchants they will have as much incentive to obtain bitcoins vs. fiat as hoarders have and will discount bitcoin prices accordingly.
