first good answer and shows merchant adoption is actually still good for something. Well, maybe there is hope if the merchants are stupid enough to accept bitcoin as volatile as it is.
The businesses I have helped LOVE bitcoin now. There is no reason to face any price swings. You could use a payment processor and give up 1% for the service. That's better than the 3% you give up to a credit card. Bitcoin also allows some businesses to capture new markets. Look at this place I know.
http://centraltexasgunworks.com/They were just another tiny gun store in Texas. They had a website, but no traffic. Then they began taking bitcoin and their online business exploded. The website you see was paid for by profits from bitcoin and they are now primarily an online store. Eventually there will be a lot of online gun shops and they will be back to competing on price, but since they went first they have revenue from people who would have never heard of them.
You can call them stupid if you want. But they are crushing it in bitcoin sales.
