I've just read an article about the accepting of bitcoin in amazon at first it is good and there are some people who uses bitcoin as mode of payment in amazon but time passes the amazon company are not getting more profit in using bitcoin and also the volatility of bitcoin is so high and their might be just get lost that is based on the article that i read.
If Amazon discourages the use of bitcoin and they stop it from using it on their site, they will only harm themselves as they will lose the customers who are willing to buy in bitcoins.
