We just launched Opportunity Cost!

It's a browser extension that converts prices into $BTC as you browse, while protecting your privacy.

No more fiat illusions. Think in #Bitcoin.

🧵Here's how it works.

https://www.opportunitycost.app/

What it does: Opportunity Cost automatically detects fiat prices on any website and converts them into BTC in real-time.

From Amazon to Airbnb, you’ll instantly see the true cost of your purchases.

Why we built it: We live in a fiat world, but the future is Bitcoin.

This tool helps you build "Bitcoin intuition" by training your mind to measure value in sound money, not debased currency.

Key Features:

1. Real-time fiat-to-BTC/sats conversion

2. Dynamic display: BTC for big numbers, sats for small

3. Works across all websites

4. Customizable display preferences

5. Lightweight & fast

6. Totally private

Opportunity Cost is 100% local processing. It doesn’t track you. It doesn’t send data. It’s fully open-source.

Supported currencies: USD, EUR, GBP, JPY, CNY, INR, CAD, AUD, CHF, SGD.

More coming soon.

Start thinking in #Bitcoin. The sooner you do, the sooner you escape the fiat illusion.

Install the extension. See the signal. Ditch the noise.

Yo this is so awesome, thank you!!! 😁 Any reason why there is not a donate option on the website?

Interesting 🤔

Let’s grind this bitchass fake economy to the ground amirite? 😂

Well done!

Great extension!

Impressive 🔥🫡

TIL:

tftc != tales from the crypt

tftc == truth for the commoner

take that, hbo! nice pivot 🤙

This is so slick! Seemlessly changes fiat prices on any site into bitcoin. This is a game changer for those of us on a bitcoin standard and price everything in sats already. Did a couple tests with bitcoin only mode and highlight mode. Incredible!

That’s pretty cool

I have been thinking for weeks that i wish something like this existed 🤩

The epitome of putting staying humble on blast

Sats/sqft is the standard for home pricing now.

🤘🧡🤘

So cool. I especially like this real estate application.

Safari?

Would be nice right

nostr:npub1vwymuey3u7mf860ndrkw3r7dz30s0srg6tqmhtjzg7umtm6rn5eq2qzugd gotta cover this on the cast, breh. Blumpkin!

In the queue just for you, bubba

I can't wait. Maybe I'll figure out my fucking fountain wallet and finally zap you something instead of being a freeloader. Anyway...have an excellent day!

It's the second segment of today's podcast.

I'm very excited to finally launch Opportunity Cost today!

You can now price the internet in bitcoin!

It's extremely rewarding to take something from a nagging idea in your mind to a working product.

Here's how we did it:

As someone who has been focused on educating people about bitcoin for 8 years, I'm always thinking about the "top of funnel" and how we can bring more people into bitcoin.

As a bitcoiner, I'm always looking for tools to make my life easier.

Opportunity Cost tries to solve for both.

For people to understand why they need bitcoin they need a way to recognize it's value prop quickly. By enabling them to download a simple extension that allows them to track the price of things in bitcoin over time we hope that people begin to recognize the power of hard money.

Those who already live on a bitcoin standard need a simple tool that can easily help them understand how much bitcoin they're spending on a day-to-day basis. Opportunity Cost solves for that.

I've often had ideas for informational bitcoin products/tools that never made it to launch because I never felt comfortable taking the risk to pay a developer to build it from scratch.

AI completely changes the game. In a span of three hours one Saturday afternoon I was able to build a working prototype via a combination of ChatGPT and Replit.

After playing with the prototype in my browsers I was successfully able to convince myself that this product was something worth pursuing. I then found nostr:nprofile1qyx8wumn8ghj7cnjvghxjmcpz4mhxue69uhk2er9dchxummnw3ezumrpdejqqgq4mqax94enxcx4ez5h2sjt4hthkqj3y5vnccj3yv0nn5w03tp5usehgwej here on Nostr, reached out to him, showed him the app and asked if he thought he could turn it into a fully functioning product.

He liked the idea, understood how I wanted it to work because of the prototype I built, and took the reins from there.

Within two weeks of Moses using his spare time to work on the app, we had a fully functioning and stable product.

The longest part of this process has been getting the app approved by the app stores. Google approved this morning and Firefox is still pending.

We're entering a brave new world in which "idea guys" who have been scoffed at historically have agency to bring their ideas to life in the form of a prototype and then hand it off to a dev who can do the rest.

Huge shout out to nostr:nprofile1qyx8wumn8ghj7cnjvghxjmcpz4mhxue69uhk2er9dchxummnw3ezumrpdejqqgq4mqax94enxcx4ez5h2sjt4hthkqj3y5vnccj3yv0nn5w03tp5usehgwej and Ed, Head of Ops at TFTC, for their work on this. Also, nostr:nprofile1qyx8wumn8ghj7cnjvghxjmcpz4mhxue69uhk2er9dchxummnw3ezumrpdejqqgq3hx5fgpxm7vp5ulscs6afm3xx6dm0ywdprqn3h5hv2eag3xzsecaq8aww and Anthony Ronning for their advice along the way.

Go download the extension and let us know what you think! The extension is only the first iteration of Opportunity Cost.

Cool. My website prices all my products in sats, too. https://mailboxmeat.com

What are ‘sats’?

Would be so cool if it redid the plots on Zillow and The Fed

Great work though! This is something I wanted to do, but the execution here is much better 👊

Awesome

So it's an "Opportunity Cost" calculator. Now I can finally see the true cost of a Cybertruck versus, say, a very nice vessel from Yachttrading https://www.yachttrading.com/. I'm not sure my heart is ready for that kind of truth, but I love the concept

Awesome stuff.

This extension converts the price to BTC, I'm worried about the pricing of yacht for sale, use it to calculate, maybe I can give the buyer some new ways to pay for bitcoin.

https://www.yachttrading.com/

Bitcoin intuition 👏🏻

Imagine that! What a great idea.

Finally a tool to cure yacht sticker shock! Watching a boat for sale price morph into BTC decimals is like seeing the Matrix in blockchain vision.

https://www.yachttrading.com/

Great! I'll try

Fuck yeah

Can we have a mode that shows a dollar price with 4 years of estimated BTC APY?

amazing, now i don't have to calculate to find sats value everytime

Love it

Nice. Now do Firefox.

This is cool. It even added sats to every value in my online banking. Past purchases, future transactions I have coming up, balances and everything. Cool, thanks.

ava for desktop too???

I have to ask, It's hard for me to use my mobile a lot.

wow, looks much easier than googling the price 🫢

WOOHA, that looks sick.

How much bounty for adding CZK currency?

20k?

congrats bruv; wen black stacking SATs hat?

[Libertad]

¿Quién dijo que la curva de adaptación para que bitcoin se convirtiera en unidad de cuenta sería complicada y llevaría años?

Aquí tienes dos tazas.

🤠😉
