I have been into bitcoin since 2014, but I spent more generational wealth than I would care to admit back then. I've heard stories of fortunes blown on cocaine in the 1980's. I could write a story about spending a fortune on Diet Mt. Dew. I don't drink Diet Mt. Dew anymore. This one time, I spent about a million sats for a light beer at a baseball game. I wouldn't say I had a drinking problem, a million sats was only five bucks at the time. I didn't know that much bitcoin would be worth over a thousand bucks eleven years later.
I don't drink beer anymore. Bitcoin tends to do that to you.
We can afford chairs now. To be honest, we need a couch. The last couch I bought was in 2017 and it cost about a whole bitcoin. That couch is buried in a landfill today. My wife loves furniture, but even she's hesitant to spend sats on a couch now. We know we need a couch, but we don't want to spend sats on something we will need to replace before the next halving.
Many of us who have been in bitcoin for more than a decade have some regrets. I know I do, but we need to live our lives. I would never say you should sit on the floor, but I encourage to you to think about time. How long will this thing I need to buy last? If you think you can give a 3 million sat couch to your grandchildren, spend three million sats on the couch. If your five year plan for the couch is to help fill a landfill, maybe you only need to buy a used couch at a thrift store. This is not investment advice of course. How can it be? I don't know what kind of couch hazards you have in your house. I have trouble finding a couch of my own, but it's how I think about making bigger purchases. How many years of your retirement will that watch, car, house or whatever cost you from your stack? You can only determine that for yourself. I think the opportunity cost app will help you keep track of your decision.
This app was made by someone who once spent a whole bitcoin on a heater. I can't speak for Marty, but I believe the opportunity cost app will help you learn from my mistakes.

Using The Opportunity Cost App
The app is pretty straight forward. It is only available on Chrome for now so I installed it on the Chromium browser. I looked at the settings, but kept them default.
Then I searched for a Rolex in Duck Duck Go.
The default is bitcoin, but there is a sat calculator in the corner too, I have always wanted a Rolex Milgauss with a green sapphire so I looked it up on eBay. It's about 8 million sats. That's too rich for my blood, but I might be willing to part with a million sats for that watch. I'll definitely pick it up for 500,000 sats. I can wait. Bitcoin is the best clock in the world. I wouldn't go so far as to call this Rolex a shitcoin, but bitcoin is a better clock than any watch in my opinion--Even when compared to my favorite watch.
