This Browser Extension Converts Everything Into Bitcoin—Here’s Why

A new browser extension converts prices on every site into Bitcoin and Sats, the smallest denomination of the orange coin. Its creator says that the extension is a step towards mass adoption, will help him in his personal life—and might even stop unnecessary purchases.

Ninja blender: 84,182 sats. Lamborghini Aventador: 3.83 BTC. A luxury five-bedroom apartment overlooking Central Park: 560 BTC. Highest-paid athlete Cristiano Ronaldo’s entire yearly earnings: 2,570 BTC.

Viewing money in Bitcoin and Sats, instead of dollars, can be refreshing and kind of funny. But, the extension’s creator says, it also opens your eyes to how much Bitcoin you could stack instead.

Opportunity Cost launched on Chrome and Brave Browser on Tuesday, with Firefox compatibility to follow soon. Immediately, it was met by social media buzz as crypto enthusiasts flocked to see their favorite products in Sats and started to realize how much Bitcoin they were spending on silly purchases.

The extension was created by Marty Bent, managing partner at investment firm Ten31 and founder of Bitcoin-focused media company TFTC, short for Truth for the Commoner.

Bent told Decrypt that the extension serves multiple purposes, but most importantly, it’s a memetic tool for normies to understand what he believes the future will look like.

Bro!!! Opportunity Cost by @TFTC21 working for the first time. This house is way too expensive, definitely not worth 24.99 bitcoin. The dollar price could be right for all I know. But start pricing in bitcoin. It’s the better, more neutral unit of account! pic.twitter.com/HUlBFZqz3C

“You can try to explain things to them. You can grab them by the shoulders, you can shake them, you can urge them to do things. Many people hear you when you do that, but not many listen,” he explained. “So I thought this app was a good way to help people see Bitcoin and really begin to conceptualize what the world would look like if Bitcoin were their money.”

Ironically, it launched the same day economist and longtime Bitcoin critic Peter Schiff said he would admit he was wrong about the cryptocurrency if everything becomes priced in Bitcoin. The Opportunity Cost extension is a step in the right direction for this to become a reality, the creator said.

.@PeterSchiff says he’ll admit he’s wrong on #bitcoin if “I wake up in a world where everything is priced in Bitcoin.”

Cool. Now open your browser.

“I don’t imagine that many people who aren’t into Bitcoin will download it at first,” Bent said. “But the power of the tool is that it can go very viral. Because people who are into Bitcoin will take screenshots of things priced in Bitcoin, share that, and the people who are outside will see that and begin, hopefully, to have questions enter their mind about Bitcoin.”

While he hates the term “Bitcoin maxi,” Bent understands that most people would label him and his company as exactly that. He says that he uses Bitcoin every day as a form of payment, and his company, TFTC, pays all of its employees at least partly in Bitcoin.

As such, the extension doubles as a tool to help his employees better understand the pricing of the products they’re purchasing.

Bent believes that Bitcoin is simply a better type of money to hold and use rather than fiat currencies because the dollar is inflationary. For that reason, he opposes the use of stablecoins, crypto tokens tied to the price of fiat currencies like the U.S. dollar.

“They’re still tethered, pun intended, to the dollar, which is being inflated every year,” he said, alluding to Tether, the issuer of the largest stablecoin USDT. “Stablecoins are inherently unstable, in the sense that they are tied to a continuously debasing currency. And so I think you want to hold better money.”



To illustrate this point further, a new feature in development will show users how products cost less Bitcoin due to its rising value, even as those same products cost more in fiat currency due to inflation.

By viewing products in Bitcoin, he also thinks that it may reduce unnecessary spending habits.

“As you’re shopping on the web and engaging in consumerism,” Bent explained, “it’s also not only to help you gage how much you’re spending in Bitcoin, but also to ask yourself the question: Would I rather have this this trinket that I’m buying online right now, or buy this much amount of Bitcoin?”

He added, “When you see a four-bedroom apartment in New York City priced at 500 Bitcoin, it forces one to question, is that apartment really worth 500 Bitcoin?”
