Pay with bitcoin is too difficult at this point I think because people need to learn what bitcoin is and how to use it and because it is volatile.

Instead people should pay via bitcoin. Lets Say I buy something from a US website but I am not from the US.
I got 3 options of payment:
pay with Paypal and it will cost me 102$
pay with bank wire  and it will cost me 100$
pay via bitcoin and it will cost me 98$

pay via bitcoin = I pay 98$ worth of my country's currency, I don't know what bitcoin is and I don't care, all I know is it is cheaper than the other methods of payments. behind the scenes BTC is bought with my country's currency and the BTC are sold for US dollars to pay the website.

So this is like "bitpay" for the client side as well.

Do you think it is possible to make this "pay via BTC" cheaper than other methods at least for international purchases?
