You doubt that would happen or that the market would explode?.
That the market would explode.
There's no additional benefit to *most* people in Amazon taking Bitcoins. Their paycheck is in dollars, their bank account is in dollars, their credit card...you get the picture.
I mean, it would be useful for people who *have* Bitcoins to be able to spend them more places, but what reason is there for me to convert my dollar to bitcoins, to buy goods...I can buy in dollars?
Especially since by the time a major retailer might be on board, mining your own bitcoins will be pretty much a dead end for most people.
