It seems that shoppers just can’t resist a bargain, even when that bargain happens online and is purchased with a fully digital cryptocurrency. Starting November 29, the website Bitcoin Black Friday promises Bitcoin holders several deals on items and services purchased across sixteen product categories. Deals will be offered on products as innocuous as gift cards and airline discounts, but in staying true to Bitcoin’s somewhat murky past, more dubious items (like unlocked mobile phones) are up for grabs as well.

The website promises that the event will be a Very Big Deal, claiming that “On November 29, Bitcoin takes holiday shopping by storm, with the best deals for Bitcoin users, and easy ways to buy all your presents and give to charity with the new, world-changing digital cash!” Users are encouraged to sign up for the opportunity to both buy and sell items. This is the second event of its kind, following last year, when “Jon Holmquist founded ‘Bitcoin Friday’, a celebration of Bitcoin with special deals for Bitcoin users,” according to the website.

For the unfamiliar, Bitcoin is a peer-to-peer digital currency that functions without the intermediation of a central authority. The concept was introduced in a 2008 paper by a pseudonymous developer known as “Satoshi Nakamoto.” The currency is revolutionary in that it it is decentralized and uses cryptography to control transactions and prevent double-spending, leading some to refer to it as a “cryptocurrency.” Despite its revolutionary nature, Bitcoin hasn’t been without its difficulties. It’s become a favorite of cybercriminals looking for an easy, untraceable way to conduct business, leading The Washington Post to label it “the currency of choice for seedy online activities.”

As to what Bitcoin Black Friday’s creators hope to accomplish, the website copy is grandiose, it not optimistic: “Bitcoin has so much potential to make the world a fairer and more prosperous place. But it needs our help. Because Bitcoin challenges such powerful industries, it will face serious political opposition– especially in the U.S. where those industries are strongest. This amazing new technology will only be politically safe once millions of people rely on it every day.”
