I do not support it because I often shop online. For Amazon using Bitcoin to pay, I think the most unacceptable point is the refund, because Bitcoin is quite unstable and the price fluctuates greatly. You can buy something for $500 in one day, but you are not satisfied with it and return it for $400 (or higher) the next day because the value of Bitcoin has changed. This has brought difficulties to enterprises. This also brings a bad experience to our users.
