But it did acknowledged that is exploring what the use of cryptocurrencies would look like on Amazon.“We believe the future will be built on new technologies that enable modern, fast, and inexpensive payments, and hope to bring that future to Amazon customers as soon as possible,” the company said.

Tom Forte, a senior research analyst who covers Amazon for the investment bank D.A. Davidson, said he doubts Amazon will accept bitcoin across its platform any time soon. Forte noted bitcoin accounts for less than 1% of transaction payments on Overstock.com, one of the few online retailers to accept the cryptocurrency.

“It’s been an effective mechanism for trading and speculation, but it hasn’t shown to date to be a form of currency for payments,” Forte said.

Proponents of bitcoin seem to have shifted their pitch from its value as a digital currency, focusing more on applying it as “store of value,” like gold or other commodities.

Bitcoin is not tied to a bank or government and allows users to spend money anonymously. The coins are created by users who “mine” them by lending computing power to verify other users’ transactions. They receive bitcoins in exchange.
