🗳️ Community Charity Vote
Coming soon — the community will vote on which charities receive our pledged sats. Focused on Bitcoin education and adoption, but not limited to it.
',p+="

Our community will vote on which charities our contributions go to. In Bitcoin, the charities will focus on Bitcoin education and adoption — but our donations are not limited to the Bitcoin ecosystem. We can find charities outside of Bitcoin that we want to support as a community.

⚠️ Donations are non-refundable. Donated XP cannot be reclaimed or reversed. Donations are a community pledge and are not tax-deductible. This is not a registered charitable organization and no tax receipts are issued.

    🚨
    "Friends in Distress" Scam
    Scammers will impersonate people you know and trust — your friends, family, even coworkers. They can:
    • Clone their profile picture, name, and bio
    • Copy their writing style and messages
    • Use AI-generated voice clones that sound exactly like them
    • Create fake emergencies — "I\'m stuck," "I need help," "send me Bitcoin and I\'ll pay you back"
    The scammer will pressure you to act fast so you don\'t have time to think or verify. They prey on your emotions and trust.
    🛡️ How to protect yourself:
    • NEVER send Bitcoin to anyone claiming to be in distress over a message
    • Verify their identity through a separate channel — call them, video chat, or meet in person
    • Real friends will understand if you take time to verify
    • Bitcoin transactions are irreversible — once sent, it\'s gone forever
    • If it feels urgent and emotional, that\'s exactly what the scammer wants

Nacho was just a young buck growing up in the White Mountains of New Hampshire — the Live Free or Die state. He spent his fawn days splashing in the Pemigewasset River, racing chipmunks through birch groves, and nibbling on leaves of debt from the forest of traditional finance. His mama always said the acorns were getting smaller every year, but nobody could explain why. One cold January day in 2009, a mysterious message appeared carved into a sugar maple: 'Chancellor on brink of second bailout for banks.' Nacho didn't understand it yet, but something had changed forever. A new kind of money had been born — one that no government could print, no bank could freeze, and no deer could counterfeit. It was called Bitcoin."},{title:"Chapter 2: The Pizza That Changed Everything",text:"Nacho heard a rumor from a blue jay passing through Franconia Notch: someone had traded 10,000 bitcoins for two pizzas. 'That's crazy!' he thought, nearly choking on a wild blueberry. But was it? Those pizzas proved Bitcoin had real value — people would actually exchange goods for it. Nacho realized this wasn't just internet magic beans. It was the beginning of price discovery. He thought about all the acorns he'd traded with the squirrels over the years — weren't those his first 'transactions' too? Every great journey starts with a single trade, and Bitcoin's started with pepperoni and cheese."},{title:"Chapter 3: Down the Rabbit Hole",text:"Nacho found a weathered copy of the whitepaper pinned to a bulletin board at a general store in Lincoln, New Hampshire. Only 9 pages, but each one hit different. Peer-to-peer. No trusted third party. Proof of work. 21 million cap. He read it by the light of a campfire near the Kancamagus Highway, the stars of the Granite State blazing overhead. The deeper he went, the more he understood: Bitcoin wasn't just new money. It was a paradigm shift. Sound money that couldn't be debased. A monetary network with no CEO, no headquarters, no off switch. Nacho's antlers tingled — literally. His first set was coming in. He was growing up, and he was becoming a Bitcoiner."},{title:"Chapter 4: HODL Through the Storm",text:"A nor'easter hit New Hampshire that winter, and the price of Bitcoin crashed right along with the temperature. Then crashed again. Nacho watched his sats lose 80% of their dollar value from a snow-covered ridge overlooking the Presidential Range. His forest friends laughed. 'Told you it was a scam!' chirped a skeptical chickadee. But Nacho had done his homework. He understood the halving cycles. He knew that every 210,000 blocks, the new supply gets cut in half. Scarcity + time = value. So Nacho did what legends do: he stood firm in the blizzard and held. Not because he was reckless, but because he understood what he held. The storms always pass. The mountains remain."},{title:"Chapter 5: Not Your Keys, Not Your Cheese",text:"One crisp autumn morning, as the New Hampshire maples blazed orange and gold, Nacho woke up to terrible news. An exchange had been hacked. Billions gone. Friends who kept their bitcoin on the exchange lost everything. A young doe from Vermont had her entire savings wiped out. Nacho felt sick — but also relieved. He'd moved his sats to a hardware wallet weeks ago, buried it in a waterproof case near his favorite granite boulder in the White Mountains. Cold storage. Air-gapped. His keys, his bitcoin. From that day forward, Nacho's motto was clear: 'Not your keys, not your cheese.' 🧀🔑 He even carved it into a birch tree so no deer would forget."},{title:"Chapter 6: The Halving",text:"Every four years, something magical happens — and Nacho had the perfect view from Mount Washington's summit. The block reward — the number of new bitcoins created with each block — gets cut in half. He watched the countdown with a group of bitcoiners who'd hiked up for the occasion, huddled together at 6,288 feet with thermoses of coffee and Lightning-powered phones. From 6.25 BTC to 3.125 BTC per block. Less new supply entering the market. Same or growing demand. The wind howled, but nobody cared. It's not magic; it's math. And it's the most predictable monetary policy in the history of money. Nacho shed a single tear — which immediately froze to his fur."},{title:"Chapter 7: Nacho's Mission",text:"Nacho looked out from his favorite overlook in the White Mountains — the same spot where he'd first read the whitepaper by campfire light. He'd grown from a gangly fawn into a strong buck with a magnificent rack of antlers (seven points, if you're counting). But so many deer — so many people — still didn't understand Bitcoin. They heard 'crypto' and thought of scams, memecoins, and celebrity tokens. But Bitcoin is different. It's the signal in the noise. So Nacho decided to dedicate his life to education, right here from the Live Free or Die state. Not shilling. Not pumping. Teaching. Because the best way to orange-pill someone isn't to tell them to buy — it's to help them understand WHY. And that's why you're here.

    Our community will vote on which charities our contributions go to. In Bitcoin, the charities will focus on Bitcoin education and adoption — but our donations are not limited to the Bitcoin ecosystem. We can find charities outside of Bitcoin that we want to support as a community.

    ⚠️ Donations are non-refundable. Donated XP cannot be reclaimed or reversed. Donations are a community pledge and are not tax-deductible. This is not a registered charitable organization and no tax receipts are issued.

    🚨
    "Friends in Distress" Scam
    Scammers will impersonate people you know and trust — your friends, family, even coworkers. They can:
    • Clone their profile picture, name, and bio
    • Copy their writing style and messages
    • Use AI-generated voice clones that sound exactly like them
    • Create fake emergencies — "I\'m stuck," "I need help," "send me Bitcoin and I\'ll pay you back"
    The scammer will pressure you to act fast so you don\'t have time to think or verify. They prey on your emotions and trust.
    🛡️ How to protect yourself:
    • NEVER send Bitcoin to anyone claiming to be in distress over a message
    • Verify their identity through a separate channel — call them, video chat, or meet in person
    • Real friends will understand if you take time to verify
    • Bitcoin transactions are irreversible — once sent, it\'s gone forever
    • If it feels urgent and emotional, that\'s exactly what the scammer wants

Nacho was just a young buck growing up in the White Mountains of New Hampshire — the Live Free or Die state. He spent his fawn days splashing in the Pemigewasset River, racing chipmunks through birch groves, and nibbling on leaves of debt from the forest of traditional finance. His mama always said the acorns were getting smaller every year, but nobody could explain why. One cold January day in 2009, a mysterious message appeared carved into a sugar maple: 'Chancellor on brink of second bailout for banks.' Nacho didn't understand it yet, but something had changed forever. A new kind of money had been born — one that no government could print, no bank could freeze, and no deer could counterfeit. It was called Bitcoin."},{title:"Chapter 2: The Pizza That Changed Everything",text:"Nacho heard a rumor from a blue jay passing through Franconia Notch: someone had traded 10,000 bitcoins for two pizzas. 'That's crazy!' he thought, nearly choking on a wild blueberry. But was it? Those pizzas proved Bitcoin had real value — people would actually exchange goods for it. Nacho realized this wasn't just internet magic beans. It was the beginning of price discovery. He thought about all the acorns he'd traded with the squirrels over the years — weren't those his first 'transactions' too? Every great journey starts with a single trade, and Bitcoin's started with pepperoni and cheese."},{title:"Chapter 3: Down the Rabbit Hole",text:"Nacho found a weathered copy of the whitepaper pinned to a bulletin board at a general store in Lincoln, New Hampshire. Only 9 pages, but each one hit different. Peer-to-peer. No trusted third party. Proof of work. 21 million cap. He read it by the light of a campfire near the Kancamagus Highway, the stars of the Granite State blazing overhead. The deeper he went, the more he understood: Bitcoin wasn't just new money. It was a paradigm shift. Sound money that couldn't be debased. A monetary network with no CEO, no headquarters, no off switch. Nacho's antlers tingled — literally. His first set was coming in. He was growing up, and he was becoming a Bitcoiner."},{title:"Chapter 4: HODL Through the Storm",text:"A nor'easter hit New Hampshire that winter, and the price of Bitcoin crashed right along with the temperature. Then crashed again. Nacho watched his sats lose 80% of their dollar value from a snow-covered ridge overlooking the Presidential Range. His forest friends laughed. 'Told you it was a scam!' chirped a skeptical chickadee. But Nacho had done his homework. He understood the halving cycles. He knew that every 210,000 blocks, the new supply gets cut in half. Scarcity + time = value. So Nacho did what legends do: he stood firm in the blizzard and held. Not because he was reckless, but because he understood what he held. The storms always pass. The mountains remain."},{title:"Chapter 5: Not Your Keys, Not Your Cheese",text:"One crisp autumn morning, as the New Hampshire maples blazed orange and gold, Nacho woke up to terrible news. An exchange had been hacked. Billions gone. Friends who kept their bitcoin on the exchange lost everything. A young doe from Vermont had her entire savings wiped out. Nacho felt sick — but also relieved. He'd moved his sats to a hardware wallet weeks ago, buried it in a waterproof case near his favorite granite boulder in the White Mountains. Cold storage. Air-gapped. His keys, his bitcoin. From that day forward, Nacho's motto was clear: 'Not your keys, not your cheese.' 🧀🔑 He even carved it into a birch tree so no deer would forget."},{title:"Chapter 6: The Halving",text:"Every four years, something magical happens — and Nacho had the perfect view from Mount Washington's summit. The block reward — the number of new bitcoins created with each block — gets cut in half. He watched the countdown with a group of bitcoiners who'd hiked up for the occasion, huddled together at 6,288 feet with thermoses of coffee and Lightning-powered phones. From 6.25 BTC to 3.125 BTC per block. Less new supply entering the market. Same or growing demand. The wind howled, but nobody cared. It's not magic; it's math. And it's the most predictable monetary policy in the history of money. Nacho shed a single tear — which immediately froze to his fur."},{title:"Chapter 7: Nacho's Mission",text:"Nacho looked out from his favorite overlook in the White Mountains — the same spot where he'd first read the whitepaper by campfire light. He'd grown from a gangly fawn into a strong buck with a magnificent rack of antlers (seven points, if you're counting). But so many deer — so many people — still didn't understand Bitcoin. They heard 'crypto' and thought of scams, memecoins, and celebrity tokens. But Bitcoin is different. It's the signal in the noise. So Nacho decided to dedicate his life to education, right here from the Live Free or Die state. Not shilling. Not pumping. Teaching. Because the best way to orange-pill someone isn't to tell them to buy — it's to help them understand WHY. And that's why you're here.

    Our community will vote on which charities our contributions go to. In Bitcoin, the charities will focus on Bitcoin education and adoption - but our donations are not limited to the Bitcoin ecosystem. We can find charities outside of Bitcoin that we want to support as a community.

    ⚠️ Donations are non-refundable. Donated XP cannot be reclaimed or reversed. Donations are a community pledge and are not tax-deductible. This is not a registered charitable organization and no tax receipts are issued.

    🚨
    "Friends in Distress" Scam
    Scammers will impersonate people you know and trust — your friends, family, even coworkers. They can:
    • Clone their profile picture, name, and bio
    • Copy their writing style and messages
    • Use AI-generated voice clones that sound exactly like them
    • Create fake emergencies — "I\'m stuck," "I need help," "send me Bitcoin and I\'ll pay you back"
    The scammer will pressure you to act fast so you don\'t have time to think or verify. They prey on your emotions and trust.
    🛡️ How to protect yourself:
    • NEVER send Bitcoin to anyone claiming to be in distress over a message
    • Verify their identity through a separate channel — call them, video chat, or meet in person
    • Real friends will understand if you take time to verify
    • Bitcoin transactions are irreversible — once sent, it\'s gone forever
    • If it feels urgent and emotional, that\'s exactly what the scammer wants

Nacho was just a young buck growing up in the White Mountains of New Hampshire — the Live Free or Die state. He spent his fawn days splashing in the Pemigewasset River, racing chipmunks through birch groves, and nibbling on leaves of debt from the forest of traditional finance. His mama always said the acorns were getting smaller every year, but nobody could explain why. One cold January day in 2009, a mysterious message appeared carved into a sugar maple: 'Chancellor on brink of second bailout for banks.' Nacho didn't understand it yet, but something had changed forever. A new kind of money had been born — one that no government could print, no bank could freeze, and no deer could counterfeit. It was called Bitcoin."},{title:"Chapter 2: The Pizza That Changed Everything",text:"Nacho heard a rumor from a blue jay passing through Franconia Notch: someone had traded 10,000 bitcoins for two pizzas. 'That's crazy!' he thought, nearly choking on a wild blueberry. But was it? Those pizzas proved Bitcoin had real value — people would actually exchange goods for it. Nacho realized this wasn't just internet magic beans. It was the beginning of price discovery. He thought about all the acorns he'd traded with the squirrels over the years — weren't those his first 'transactions' too? Every great journey starts with a single trade, and Bitcoin's started with pepperoni and cheese."},{title:"Chapter 3: Down the Rabbit Hole",text:"Nacho found a weathered copy of the whitepaper pinned to a bulletin board at a general store in Lincoln, New Hampshire. Only 9 pages, but each one hit different. Peer-to-peer. No trusted third party. Proof of work. 21 million cap. He read it by the light of a campfire near the Kancamagus Highway, the stars of the Granite State blazing overhead. The deeper he went, the more he understood: Bitcoin wasn't just new money. It was a paradigm shift. Sound money that couldn't be debased. A monetary network with no CEO, no headquarters, no off switch. Nacho's antlers tingled — literally. His first set was coming in. He was growing up, and he was becoming a Bitcoiner."},{title:"Chapter 4: HODL Through the Storm",text:"A nor'easter hit New Hampshire that winter, and the price of Bitcoin crashed right along with the temperature. Then crashed again. Nacho watched his sats lose 80% of their dollar value from a snow-covered ridge overlooking the Presidential Range. His forest friends laughed. 'Told you it was a scam!' chirped a skeptical chickadee. But Nacho had done his homework. He understood the halving cycles. He knew that every 210,000 blocks, the new supply gets cut in half. Scarcity + time = value. So Nacho did what legends do: he stood firm in the blizzard and held. Not because he was reckless, but because he understood what he held. The storms always pass. The mountains remain."},{title:"Chapter 5: Not Your Keys, Not Your Cheese",text:"One crisp autumn morning, as the New Hampshire maples blazed orange and gold, Nacho woke up to terrible news. An exchange had been hacked. Billions gone. Friends who kept their bitcoin on the exchange lost everything. A young doe from Vermont had her entire savings wiped out. Nacho felt sick — but also relieved. He'd moved his sats to a hardware wallet weeks ago, buried it in a waterproof case near his favorite granite boulder in the White Mountains. Cold storage. Air-gapped. His keys, his bitcoin. From that day forward, Nacho's motto was clear: 'Not your keys, not your cheese.' 🧀🔑 He even carved it into a birch tree so no deer would forget."},{title:"Chapter 6: The Halving",text:"Every four years, something magical happens — and Nacho had the perfect view from Mount Washington's summit. The block reward — the number of new bitcoins created with each block — gets cut in half. He watched the countdown with a group of bitcoiners who'd hiked up for the occasion, huddled together at 6,288 feet with thermoses of coffee and Lightning-powered phones. From 6.25 BTC to 3.125 BTC per block. Less new supply entering the market. Same or growing demand. The wind howled, but nobody cared. It's not magic; it's math. And it's the most predictable monetary policy in the history of money. Nacho shed a single tear — which immediately froze to his fur."},{title:"Chapter 7: Nacho's Mission",text:"Nacho looked out from his favorite overlook in the White Mountains — the same spot where he'd first read the whitepaper by campfire light. He'd grown from a gangly fawn into a strong buck with a magnificent rack of antlers (seven points, if you're counting). But so many deer — so many people — still didn't understand Bitcoin. They heard 'crypto' and thought of scams, memecoins, and celebrity tokens. But Bitcoin is different. It's the signal in the noise. So Nacho decided to dedicate his life to education, right here from the Live Free or Die state. Not shilling. Not pumping. Teaching. Because the best way to orange-pill someone isn't to tell them to buy — it's to help them understand WHY. And that's why you're here.

    🚨
    "Friends in Distress" Scam
    Scammers will impersonate people you know and trust — your friends, family, even coworkers. They can:
    • Clone their profile picture, name, and bio
    • Copy their writing style and messages
    • Use AI-generated voice clones that sound exactly like them
    • Create fake emergencies — "I\'m stuck," "I need help," "send me Bitcoin and I\'ll pay you back"
    The scammer will pressure you to act fast so you don\'t have time to think or verify. They prey on your emotions and trust.
    🛡️ How to protect yourself:
    • NEVER send Bitcoin to anyone claiming to be in distress over a message
    • Verify their identity through a separate channel — call them, video chat, or meet in person
    • Real friends will understand if you take time to verify
    • Bitcoin transactions are irreversible — once sent, it\'s gone forever
    • If it feels urgent and emotional, that\'s exactly what the scammer wants

Nacho was just a young buck growing up in the White Mountains of New Hampshire — the Live Free or Die state. He spent his fawn days splashing in the Pemigewasset River, racing chipmunks through birch groves, and nibbling on leaves of debt from the forest of traditional finance. His mama always said the acorns were getting smaller every year, but nobody could explain why. One cold January day in 2009, a mysterious message appeared carved into a sugar maple: 'Chancellor on brink of second bailout for banks.' Nacho didn't understand it yet, but something had changed forever. A new kind of money had been born — one that no government could print, no bank could freeze, and no deer could counterfeit. It was called Bitcoin."},{title:"Chapter 2: The Pizza That Changed Everything",text:"Nacho heard a rumor from a blue jay passing through Franconia Notch: someone had traded 10,000 bitcoins for two pizzas. 'That's crazy!' he thought, nearly choking on a wild blueberry. But was it? Those pizzas proved Bitcoin had real value — people would actually exchange goods for it. Nacho realized this wasn't just internet magic beans. It was the beginning of price discovery. He thought about all the acorns he'd traded with the squirrels over the years — weren't those his first 'transactions' too? Every great journey starts with a single trade, and Bitcoin's started with pepperoni and cheese."},{title:"Chapter 3: Down the Rabbit Hole",text:"Nacho found a weathered copy of the whitepaper pinned to a bulletin board at a general store in Lincoln, New Hampshire. Only 9 pages, but each one hit different. Peer-to-peer. No trusted third party. Proof of work. 21 million cap. He read it by the light of a campfire near the Kancamagus Highway, the stars of the Granite State blazing overhead. The deeper he went, the more he understood: Bitcoin wasn't just new money. It was a paradigm shift. Sound money that couldn't be debased. A monetary network with no CEO, no headquarters, no off switch. Nacho's antlers tingled — literally. His first set was coming in. He was growing up, and he was becoming a Bitcoiner."},{title:"Chapter 4: HODL Through the Storm",text:"A nor'easter hit New Hampshire that winter, and the price of Bitcoin crashed right along with the temperature. Then crashed again. Nacho watched his sats lose 80% of their dollar value from a snow-covered ridge overlooking the Presidential Range. His forest friends laughed. 'Told you it was a scam!' chirped a skeptical chickadee. But Nacho had done his homework. He understood the halving cycles. He knew that every 210,000 blocks, the new supply gets cut in half. Scarcity + time = value. So Nacho did what legends do: he stood firm in the blizzard and held. Not because he was reckless, but because he understood what he held. The storms always pass. The mountains remain."},{title:"Chapter 5: Not Your Keys, Not Your Cheese",text:"One crisp autumn morning, as the New Hampshire maples blazed orange and gold, Nacho woke up to terrible news. An exchange had been hacked. Billions gone. Friends who kept their bitcoin on the exchange lost everything. A young doe from Vermont had her entire savings wiped out. Nacho felt sick — but also relieved. He'd moved his sats to a hardware wallet weeks ago, buried it in a waterproof case near his favorite granite boulder in the White Mountains. Cold storage. Air-gapped. His keys, his bitcoin. From that day forward, Nacho's motto was clear: 'Not your keys, not your cheese.' 🧀🔑 He even carved it into a birch tree so no deer would forget."},{title:"Chapter 6: The Halving",text:"Every four years, something magical happens — and Nacho had the perfect view from Mount Washington's summit. The block reward — the number of new bitcoins created with each block — gets cut in half. He watched the countdown with a group of bitcoiners who'd hiked up for the occasion, huddled together at 6,288 feet with thermoses of coffee and Lightning-powered phones. From 6.25 BTC to 3.125 BTC per block. Less new supply entering the market. Same or growing demand. The wind howled, but nobody cared. It's not magic; it's math. And it's the most predictable monetary policy in the history of money. Nacho shed a single tear — which immediately froze to his fur."},{title:"Chapter 7: Nacho's Mission",text:"Nacho looked out from his favorite overlook in the White Mountains — the same spot where he'd first read the whitepaper by campfire light. He'd grown from a gangly fawn into a strong buck with a magnificent rack of antlers (seven points, if you're counting). But so many deer — so many people — still didn't understand Bitcoin. They heard 'crypto' and thought of scams, memecoins, and celebrity tokens. But Bitcoin is different. It's the signal in the noise. So Nacho decided to dedicate his life to education, right here from the Live Free or Die state. Not shilling. Not pumping. Teaching. Because the best way to orange-pill someone isn't to tell them to buy — it's to help them understand WHY. And that's why you're here.

    🚨
    "Friends in Distress" Scam
    Scammers will impersonate people you know and trust — your friends, family, even coworkers. They can:
    • Clone their profile picture, name, and bio
    • Copy their writing style and messages
    • Use AI-generated voice clones that sound exactly like them
    • Create fake emergencies — "I\'m stuck," "I need help," "send me Bitcoin and I\'ll pay you back"
    The scammer will pressure you to act fast so you don\'t have time to think or verify. They prey on your emotions and trust.
    🛡️ How to protect yourself:
    • NEVER send Bitcoin to anyone claiming to be in distress over a message
    • Verify their identity through a separate channel — call them, video chat, or meet in person
    • Real friends will understand if you take time to verify
    • Bitcoin transactions are irreversible — once sent, it\'s gone forever
    • If it feels urgent and emotional, that\'s exactly what the scammer wants

Nacho was just a young buck growing up in the White Mountains of New Hampshire — the Live Free or Die state. He spent his fawn days splashing in the Pemigewasset River, racing chipmunks through birch groves, and nibbling on leaves of debt from the forest of traditional finance. His mama always said the acorns were getting smaller every year, but nobody could explain why. One cold January day in 2009, a mysterious message appeared carved into a sugar maple: 'Chancellor on brink of second bailout for banks.' Nacho didn't understand it yet, but something had changed forever. A new kind of money had been born — one that no government could print, no bank could freeze, and no deer could counterfeit. It was called Bitcoin."},{title:"Chapter 2: The Pizza That Changed Everything",text:"Nacho heard a rumor from a blue jay passing through Franconia Notch: someone had traded 10,000 bitcoins for two pizzas. 'That's crazy!' he thought, nearly choking on a wild blueberry. But was it? Those pizzas proved Bitcoin had real value — people would actually exchange goods for it. Nacho realized this wasn't just internet magic beans. It was the beginning of price discovery. He thought about all the acorns he'd traded with the squirrels over the years — weren't those his first 'transactions' too? Every great journey starts with a single trade, and Bitcoin's started with pepperoni and cheese."},{title:"Chapter 3: Down the Rabbit Hole",text:"Nacho found a weathered copy of the whitepaper pinned to a bulletin board at a general store in Lincoln, New Hampshire. Only 9 pages, but each one hit different. Peer-to-peer. No trusted third party. Proof of work. 21 million cap. He read it by the light of a campfire near the Kancamagus Highway, the stars of the Granite State blazing overhead. The deeper he went, the more he understood: Bitcoin wasn't just new money. It was a paradigm shift. Sound money that couldn't be debased. A monetary network with no CEO, no headquarters, no off switch. Nacho's antlers tingled — literally. His first set was coming in. He was growing up, and he was becoming a Bitcoiner."},{title:"Chapter 4: HODL Through the Storm",text:"A nor'easter hit New Hampshire that winter, and the price of Bitcoin crashed right along with the temperature. Then crashed again. Nacho watched his sats lose 80% of their dollar value from a snow-covered ridge overlooking the Presidential Range. His forest friends laughed. 'Told you it was a scam!' chirped a skeptical chickadee. But Nacho had done his homework. He understood the halving cycles. He knew that every 210,000 blocks, the new supply gets cut in half. Scarcity + time = value. So Nacho did what legends do: he stood firm in the blizzard and held. Not because he was reckless, but because he understood what he held. The storms always pass. The mountains remain."},{title:"Chapter 5: Not Your Keys, Not Your Cheese",text:"One crisp autumn morning, as the New Hampshire maples blazed orange and gold, Nacho woke up to terrible news. An exchange had been hacked. Billions gone. Friends who kept their bitcoin on the exchange lost everything. A young doe from Vermont had her entire savings wiped out. Nacho felt sick — but also relieved. He'd moved his sats to a hardware wallet weeks ago, buried it in a waterproof case near his favorite granite boulder in the White Mountains. Cold storage. Air-gapped. His keys, his bitcoin. From that day forward, Nacho's motto was clear: 'Not your keys, not your cheese.' 🧀🔑 He even carved it into a birch tree so no deer would forget."},{title:"Chapter 6: The Halving",text:"Every four years, something magical happens — and Nacho had the perfect view from Mount Washington's summit. The block reward — the number of new bitcoins created with each block — gets cut in half. He watched the countdown with a group of bitcoiners who'd hiked up for the occasion, huddled together at 6,288 feet with thermoses of coffee and Lightning-powered phones. From 6.25 BTC to 3.125 BTC per block. Less new supply entering the market. Same or growing demand. The wind howled, but nobody cared. It's not magic; it's math. And it's the most predictable monetary policy in the history of money. Nacho shed a single tear — which immediately froze to his fur."},{title:"Chapter 7: Nacho's Mission",text:"Nacho looked out from his favorite overlook in the White Mountains — the same spot where he'd first read the whitepaper by campfire light. He'd grown from a gangly fawn into a strong buck with a magnificent rack of antlers (seven points, if you're counting). But so many deer — so many people — still didn't understand Bitcoin. They heard 'crypto' and thought of scams, memecoins, and celebrity tokens. But Bitcoin is different. It's the signal in the noise. So Nacho decided to dedicate his life to education, right here from the Live Free or Die state. Not shilling. Not pumping. Teaching. Because the best way to orange-pill someone isn't to tell them to buy — it's to help them understand WHY. And that's why you're here.
