Carlos had spent most of his life chasing the immediate. Raised in a world of credit cards, instant loans, and one-click gratification, he thought little about the future. His life was a blur of impulse purchases, late-night takeouts, and fleeting relationships. The idea of saving for tomorrow seemed distant, even irrelevant. "What’s the point?" he often thought. After all, life was for living, not planning.
But then came the crash—the financial one and his own.
The Beginning of the Shift
It started with a friend handing him a book about Bitcoin. Carlos was skeptical, brushing it off as some get-rich-quick scheme. But curiosity got the better of him. As he read, he was struck not by the promise of wealth but by the philosophy behind it: the idea of limited supply, self-sovereignty, and a system that rewarded patience over haste. It was like staring into a mirror that reflected all his shortcomings—his lack of discipline, his disregard for tomorrow. He felt exposed but also strangely hopeful.
So he bought his first Bitcoin—not much, just a small amount to experiment. At first, he checked the price obsessively, watching every tick of volatility with anxiety. But over time, something changed. Carlos began to see Bitcoin not as a quick profit but as a long-term store of value, something to hold onto and nurture. It wasn’t just his finances that began to shift—his entire perspective on life started evolving.
Lesson One: Health
The first wake-up call came when Carlos realized he couldn’t enjoy his wealth if he didn’t have his health. Years of neglect—junk food, sleepless nights, and sedentary habits—had taken their toll. He saw his doctor for the first time in years, and the numbers weren’t good.
"Do you want to be around to see your future?" the doctor asked. The words struck like a hammer. Carlos thought about Bitcoin, about how it rewards the patient and the disciplined. He decided his health deserved the same respect.
Carlos started small. He walked every evening, traded processed snacks for fresh meals, and even took up strength training. It was painful at first—his body rebelled against the sudden change—but as months turned into years, he grew stronger, healthier. And with every milestone, he felt the same sense of accomplishment he got from watching his Bitcoin wallet grow.
Lesson Two: Family
Carlos hadn’t spoken to his father in months. They’d had a falling out years ago, and both were too stubborn to reconcile. But as Carlos dove deeper into the world of Bitcoin, he stumbled upon the idea of generational wealth. It wasn’t just about money—it was about legacy, about passing down lessons and values.
One night, Carlos picked up the phone. "Dad," he said, his voice shaky, "I want to talk." The conversation was awkward, but it opened a door. Over time, they rebuilt their relationship, sharing dinners and stories like they used to. Carlos even introduced his father to Bitcoin, and together they planned how to secure their family's future.
Carlos also started thinking about building his own family someday. The idea of being a father scared him, but it also filled him with purpose. He wanted to be someone his children could look up to—a man who embodied the values of patience, responsibility, and love.
Lesson Three: Life
Carlos used to live paycheck to paycheck, spending on things that brought fleeting joy but no real fulfillment. But as he embraced the philosophy of Bitcoin, he began to see the world differently. He downsized his life, selling off possessions he didn’t need and focusing on what truly mattered.
He started investing time in things that gave him lasting satisfaction: learning new skills, helping his community, and pursuing passions he’d long ignored. Carlos even began playing the guitar he’d bought years ago but never touched, finding solace in the quiet strum of strings.
One day, he looked around his modest apartment and realized he was happier than he’d ever been. His life wasn’t filled with flashy things, but it was rich in meaning. He had a growing savings, a healthier body, a renewed relationship with his family, and a vision for the future.
The Man He Became
Carlos often thought about the man he was before Bitcoin—impulsive, aimless, and trapped in a cycle of short-term thinking. That man seemed like a stranger now. Bitcoin hadn’t just changed his financial habits; it had rewired his brain, teaching him to value the long term in every aspect of life.
He began sharing his story, hoping to inspire others. He spoke about the lessons he learned, not in abstract terms, but in the raw, emotional journey he’d lived. People listened, not because Carlos was wealthy but because he was real. He’d walked the path from chaos to clarity, from consumption to creation.
And as he told his story, he always ended with a smile, saying, "Bitcoin taught me that the best things in life take time—whether it’s building wealth, strengthening relationships, or becoming the person you’re meant to be."
Carlos knew the journey was far from over, but for the first time, he was looking forward to the road ahead.

I used to think I had it all figured out. I was the kind of guy who measured success by the numbers in his bank account, the recognition of peers, and the comfort of feeling in control. My ego was my compass, steering me toward what I thought was power, status, and security. But deep down, I was restless. Something was missing, though I couldn’t put it into words. That’s when I discovered Bitcoin.
At first, it was about the price. I saw the headlines, the promises of wealth, the idea of being part of something revolutionary. Like so many others, I came for the gains. But Bitcoin doesn’t let you stay shallow for long—it challenges you, humbles you, and teaches you lessons you didn’t know you needed.
The first lesson came fast: control is an illusion. I watched Bitcoin’s price swing wildly, from euphoric highs to gut-wrenching lows. At first, I thought I could outsmart the market. I made trades, confident in my “skills,” only to lose more than I gained. Bitcoin didn’t care about my ego or my plans. It was a mirror, reflecting my arrogance and showing me just how little control I really had. Slowly, I learned to detach—to stop chasing the price and start appreciating the protocol for what it was: a system bigger than me, beyond my control, and yet profoundly fair.
Then came the lesson of responsibility. I’ll never forget the day I transferred my first significant amount of Bitcoin to my hardware wallet. The weight of it hit me like a ton of bricks: there was no help desk, no “reset password” button, no institution to call if I messed up. It was terrifying, but also liberating. For the first time, I realized what true sovereignty felt like. But with that sovereignty came a humbling truth: I had no one to blame but myself if I failed. Bitcoin forced me to take accountability for my actions—a lesson that spilled over into other areas of my life.
As I dug deeper, I started to understand Bitcoin’s incentives. Miners, Lightning nodes, developers—all acting in their self-interest, yet somehow creating a system that benefits everyone. It was a revelation. I began to see how my own ego had often blinded me to collaboration, to the idea that aligning individual goals with collective good could create something far greater than the sum of its parts. Bitcoin taught me that self-interest doesn’t have to be selfish. It can be channeled toward something meaningful, something that uplifts rather than tears down.
The hardest lesson, though, was letting go of my pride. Bitcoin doesn’t care who you are, how much money you’ve made, or what titles you hold. It operates on math, consensus, and immutable rules. The protocol humbled me in ways I didn’t expect, showing me that my worth wasn’t tied to external accolades but to my values, my integrity, and my ability to grow.
And grow I did. Bitcoin’s ethos of long-term thinking seeped into my mindset. I stopped chasing instant gratification—not just in investing, but in life. I began valuing patience, discipline, and the kind of legacy that takes years, even decades, to build. It wasn’t just about stacking sats anymore; it was about building a life rooted in principles that would outlast me.
Along the way, I started to see parallels between Bitcoin and life’s deeper lessons. Just as the protocol acknowledges human imperfection and channels it into something productive, I began to accept my own flaws. I learned to forgive—myself and others—because, like Bitcoin miners following incentives, we’re all just doing our best with the systems we’re in. I learned to love more openly, to let go of the petty need to always be “right,” and to find joy in contributing to something bigger than myself.
Today, Bitcoin is still part of my life, but it’s no longer just about the technology or the wealth it can generate. It’s a philosophy, a teacher, a constant reminder that while I’m only human, I can strive to be better. It taught me to let go of my ego, to embrace responsibility, to think long-term, and to align my self-interest with the greater good.
Bitcoin didn’t just change my finances—it changed me. And for that, I’m grateful.

Throughout the entire journey of Chain Duel, the game has been played by hundreds of people across various Bitcoin conferences and meetups, accumulating thousands of games. This experience has provided a unique perspective on how users from different geographic regions and technical backgrounds interact with the Lightning Network. Users' familiarity with Lightning often dictates their choice of tools. Many beginners and those less focused on maintaining complete control over their funds opt for easy-to-use solutions like Wallet of Satoshi because of its convenience and low fees. However, advanced users, particularly those concerned with neutrality, tend to prefer solutions like Phoenix or Zeus wallets. These wallets allow for more control over their funds by running a standalone node on their phone or connecting to their own remote Bitcoin payments infrastructure. Geography also play a significant role in shaping the experience. For example, both Wallet of Satoshi and Phoenix do not operate in the United States due to fears of possible regulations. This creates challenges for North American users at conferences, limiting their options and adding barriers to adopting and interacting with Chain Duel. Furthermore, many attendees at Bitcoin conferences arrive without a Lightning wallet at all. They often attend these events to learn more about the technology or because they view Bitcoin as an investment asset instead of an usable currency, with some attendees even expressing confusion or mistrust over how it works. Many users are unsure whether Lightning's fast and cheap transactions compromise the trustless nature of Bitcoin or how it fits within Bitcoin's broader goals of decentralization and censorship resistance. Some Bitcoin advocates criticize the Lightning Network itself. They argue that adoption is slow or they may see inherent flaws in the architecture that hinder scalability or neutrality. Such perspectives make the adoption of games like Chain Duel more challenging, as they rely on Lightning payments. However, they also highlight the importance of educating users on the protocol's technical merits and use cases. Chain Duel’s presence at these conferences has demonstrated not only the game's entertainment value but also its potential as a tool for educating the public about Bitcoin and the Lightning Network. Each player interaction is an opportunity to showcase the benefits of instant, low-fee payments that maintain neutrality in a fun, competitive environment. The challenges encountered reinforce the need for education, and through projects like Chain Duel, many are learning the practical applications of Bitcoin and Lightning in real time.

Can't zap you because your LNURL server doesn't "allowsNostr":true

2024-09-04 10:49:21

Despite its growing popularity and utility, LNURL has faced criticism particularly concerning its alignment with Bitcoin’s foundational principles. Critics argue that LNURL's reliance on an internet server to facilitate the protocol incentivizes the use of custodial services, potentially introducing trusted parties into a system that is fundamentally designed to operate without them.
This reliance could be seen as a departure from Bitcoin’s ethos of providing a trustless form of money, sparking debate about the balance between enhancing usability and maintaining the decentralized, permissionless nature of Bitcoin.

does the bitaxe runs its own full node or you just connect it to a pool? i never tried one

2024-09-01 20:35:30

Increasing the block size would increase the burden on node operators, as more resources are required to validate and store the ledger. This would likely lead to a decrease in the number of full nodes, further centralizing the network and undermining its security.
A prerequisite to prevent that kind of centralization from occurring requires the ability for bitcoin to be validated by a consumer level computer on a retail internet connection.

- For the people asking about Chain Duel:
you can find more info on chainduel(.)net or nostr reposts in my profile
- I wish I asked for a comment or quote instead of just repost. It would've been much less work 😄
- Some people didn't have a lightning address set up so I couldn't send them the sats!
- if I missed your repost: it wasn't easy to handle at the notifications but I did my best to keep up.
Thank you all and hope to see you in the next bitcoin conference at the Chain Duel area 🐍 🎮

Chain Duel was designed with bitcoin in mind.
Not only it's fun and competitive but and also an excellent tool for bitcoin adoption and education.

Hey there! I'm Francis, I created a lightning game called Chain Duel 🐍
I love Bitcoin and Nostr.
To spread the love, the first 100 people to repost this will get 210 sats each!

There were blocks when the miner didn't claim the full reward, or any at all. Bitcoin is scarce af
