1What is Bitcoin?Trial 2 minutes
Imagine a world where you can send money directly to anyone, anywhere, without needing a bank or a payment processor to mediate the transaction. This is not a futuristic concept; it’s the reality Bitcoin introduced in 2009, fundamentally reshaping how we think about money and trust. In this lesson, we delve into the fascinating concept of Bitcoin—a digital asset that allows for peer-to-peer transactions based on cryptographic proof. But Bitcoin’s significance goes far beyond digital currency; it's a movement challenging traditional finance. How does this work? And more importantly, what does it mean for the future of global finance and technology? Let's find out how this transformative technology fits into the wider world of cryptocurrencies and the Crypto Is FIRE (CFIRE) training program. At its core, Bitcoin is a peer-to-peer electronic cash system that solves one of the most significant challenges in digital payments: trust. Traditionally, when you transfer money, you rely on a bank or financial institution to verify the transaction. But with Bitcoin, trust is no longer necessary. Instead, cryptographic proof takes its place, allowing two parties to exchange value without the need for intermediaries.

2Legendary Treasure of Satoshi NakamotoTrial 38 minutes
What happens when a mysterious figure gives the world a tool that challenges everything we think we know about money, power, and freedom? This is the central question that emerges when exploring the story of Bitcoin’s creation by the elusive Satoshi Nakamoto. In a world where financial systems are controlled by central banks and governments, the arrival of a decentralized, digital currency like Bitcoin is nothing short of revolutionary. But beyond the technical details, the story of Bitcoin invites us into a deeper exploration of what money means, what power truly is, and how the absence of a creator shapes the identity of a system. This lesson digs into the fascinating narrative of Bitcoin’s birth and the disappearance of its creator, offering a critical analysis that connects this tale to broader financial and technological trends, including the growing world of cryptocurrencies and decentralized finance (DeFi).

3Bitcoin Getting StartedTrial 23 minutes
The lesson begins by addressing a fundamental issue: the vast majority of people, even those holding Bitcoin, don’t fully understand what it is or how it works. By breaking down its core functions, the lesson introduces Bitcoin as digital cash—a system that enables direct peer-to-peer transactions without the need for intermediaries like banks. It emphasizes how traditional systems often require middlemen (banks, PayPal) who slow down the process and introduce extra costs. Bitcoin eliminates this, providing a quicker, more transparent system where you don’t have to trust any third party.
Key to this concept is Bitcoin’s blockchain—a distributed ledger system that ensures security and transparency without needing centralized oversight. The lesson further explains Bitcoin’s mining process, the importance of private keys, and the revolutionary idea of self-custody, where individuals control their own funds without needing banks. It ends with a crucial takeaway: for those delving into Bitcoin, self-custody is paramount—holding your private keys ensures that no one else has access to your funds, reinforcing Bitcoin’s core value of decentralization.

4Bitcoin Halving 4 Year CycleTrial 8 minutes
Bitcoin halving is one of the most significant mechanisms that makes Bitcoin unique in the cryptocurrency world. Every four years, the reward given to miners is cut in half, reducing the rate at which new Bitcoins enter circulation. This ensures Bitcoin's scarcity, much like gold, and makes it a strong hedge against inflation compared to traditional fiat currencies. In this lesson, you'll learn the fascinating details behind Bitcoin halving, the blockchain mechanisms that keep the network secure, and the impacts of halving on miners, investors, and the overall Bitcoin ecosystem. This comprehensive exploration will empower you with a deeper understanding of why Bitcoin halving is essential to maintaining Bitcoin's value and how it shapes the future of cryptocurrency. Dive in to discover why Bitcoin’s fixed supply, combined with halving events, drives its unique economic principles and potential for long-term value growth.

5Stock to Flow Model Predicts Bitcoin’s Price?Trial 6 minutes
What if you could predict the future value of Bitcoin? Imagine knowing in 2013 that a $67 investment in Bitcoin would soar to over $60,000 by 2024. A tantalizing thought for any investor! Enter the Stock-to-Flow (S2F) model, a method designed to predict asset prices based on scarcity. Developed by the anonymous Plan B in 2019, S2F has captivated the cryptocurrency world by suggesting that Bitcoin’s value could reach new heights based on its inherent scarcity.
In this lesson, we’ll explore the Stock-to-Flow model, a popular tool in both traditional finance and crypto communities, and its relevance in predicting Bitcoin’s price. But we won’t stop there—we’ll critically examine whether this model holds up under scrutiny and look at how it might shape the future of crypto. Buckle up! This topic fits perfectly within the Crypto Is FIRE (CFIRE) training program, helping you gain deeper insight into the price dynamics of Bitcoin.

7Hacking $4.5 billion of BTCTrial 13 minutes
The heart of this lesson we’re analyzing lies in the 2016 Bitfinex hack, where 120,000 Bitcoin—worth $71 million at the time—were stolen. Fast forward to 2022, and that stolen stash had ballooned to a jaw-dropping $4.5 billion. Yet, the thieves found themselves in a financial straitjacket. Why? Because Bitcoin’s ledger is a transparent public record, meaning every move those hackers made was under the watchful eyes of law enforcement. The thieves attempted to launder the funds through thousands of smaller transactions, purchasing altcoins and NFTs along the way, but their efforts ultimately led to their arrest.
The main thesis of the video emphasizes that while blockchain itself is virtually unhackable, the same cannot be said for exchanges. This distinction between blockchain’s security and the vulnerability of crypto exchanges is vital to understanding the risks and responsibilities of being in the crypto space. The video underscores that if someone gets access to your private keys, your crypto is gone—forever. Thus, the core message here is about safeguarding your digital assets, primarily through practices like using cold wallets and multi-signature protections.

8Bitcoin Path To $10 MillionTrial 14 minutes
Imagine a world where a single Bitcoin could be worth $10 million. Sounds fantastical? According to some, this future might not be as far-fetched as it seems. The idea of Bitcoin reaching such astronomical heights has become a topic of heated debate, not just among crypto enthusiasts but within central banking circles. The European Central Bank (ECB) recently released a paper discussing the potential "redistributive effects" of Bitcoin, claiming that its rise could impoverish those outside the crypto space.
In this lesson, we’ll explore why traditional financial institutions like the ECB are increasingly worried about Bitcoin’s trajectory, what it means for the future of money, and how these concepts connect with the broader world of cryptocurrency and blockchain. As we unpack the arguments presented, we’ll also draw parallels to decentralized finance (DeFi) and its potential to reshape global markets. Welcome to the future of finance, where Bitcoin stands as both a disruptor and a lifeline.

9No-CoinersTrial 2 minutes
Bitcoin, the world’s most famous cryptocurrency, has inspired both ardent supporters and fierce skeptics. Those who reject it, known colloquially as "no-coiners," often base their arguments on fear, uncertainty, and doubt (FUD). This lesson provides a fascinating exploration of these common objections, as explained through the perspective of a no-coiner. While these fears are understandable, a critical look reveals that most are grounded in misunderstanding rather than fact. This analysis is timely, given Bitcoin's increasing relevance in global finance and its ability to challenge traditional economic norms.
We’ll dissect common no-coiner arguments—such as Bitcoin's lack of "intrinsic value" and vulnerability to asset seizure—and explore how these critiques reflect deeper misconceptions about decentralized technology. As part of the Crypto Is FIRE (CFIRE) training program, this lesson will give you the tools to both understand and counteract the FUD that surrounds Bitcoin and cryptocurrency.
-
10Bitcoin Retirement StrategyTrial 9 minutes
The lesson presents a clear thesis: traditional retirement strategies—where you save, invest, and spend down your assets—are fundamentally flawed. Instead, the wealthy don’t sell their appreciating assets; they borrow against them to create cash flow, allowing their wealth to grow while living off tax-free debt. This same principle can be applied to Bitcoin, an asset that has historically appreciated far faster than most traditional investments.
One of the most striking arguments presented is that people are playing the wrong "game" with their money. Instead of focusing on accumulating fiat currency and gradually depleting it, the goal should be to accumulate hard assets like Bitcoin and leverage them to generate income. This approach allows you to avoid taxes and keep your assets appreciating over time. The lesson also emphasizes the power of compounding growth, showing that Bitcoin’s historical average return of 200% per year could revolutionize wealth-building strategies.

11When All 21 Million Bitcoin Are MinedTrial 6 minutes
In this lesson, we’ll explore one of Bitcoin’s most fundamental characteristics: its capped supply of 21 million coins. We’ll examine the dynamics of Bitcoin mining, how miners are incentivized, and what happens when all Bitcoin has been mined. This discussion bridges traditional economic principles, such as scarcity and supply, with blockchain innovation. By understanding these mechanics, you’ll grasp why Bitcoin has been compared to finite resources like gold, and more importantly, what the future might hold for Bitcoin's ecosystem as we approach the 21 million coin cap.
-
12FILM: God Bless BitcoinTrial 90 minutes
At the heart of this lesson is the story of how the abandonment of the gold standard in 1971 unleashed a tidal wave of inflation and financial instability. With President Nixon’s decision to remove the dollar’s gold backing, governments gained the ability to print money freely, diluting the value of every dollar in circulation. The lesson draws a clear connection between this policy shift and the increasing economic inequality we see today. People are not only working harder to keep up with inflation, but their wages are not rising fast enough to offset the shrinking value of their money.
The main thesis of the lesson is clear: Bitcoin offers a return to “sound money,” an economic system where the currency retains its value over time. With its fixed supply of 21 million coins, Bitcoin represents a break from the inflationary policies that have plagued fiat currencies. The video also makes an eye-opening claim: that central banks and governments manipulate money to benefit the wealthy, turning everyday workers into debt slaves. This statement alone invites deeper examination.
-
13Bitcoin is Generational WealthTrial 14 minutes
The lesson takes us on a journey through three pivotal periods—1948, 2008, and a speculative vision of 2048. It begins with the aftermath of World War II, where families lost everything and had to rebuild from scratch, teaching future generations about the dangers of economic collapse and the importance of protecting wealth. Fast forward to 2008, a time when financial institutions faltered, and governments turned to money printing as a lifeline, leading to inflation and economic inequality. Against this backdrop, Bitcoin was introduced as a potential hedge against these vulnerabilities—a decentralized form of money that promised to be immune to the failings of traditional systems. By 2048, the narrative envisions a world where Bitcoin’s principles have safeguarded families from financial ruin, enabling prosperity and stability that outlasts the cyclical crises of the past. This sweeping narrative challenges the reader to consider whether Bitcoin’s fixed supply and decentralized nature could indeed pave the way for a more equitable future.
-
14Michael Saylor Bitcoin 2024 KeynoteTrial 37 minutes
In this lesson, we’ll explore the transformative potential of Bitcoin as a tool for capital preservation, comparing it to traditional financial and physical assets. We'll dissect why Michael Saylor sees Bitcoin as "digital capital" with the potential to reshape the global economy. You’ll learn how traditional concepts of wealth and asset management intersect with the world of cryptocurrencies, providing insight into why Bitcoin might be the solution to long-standing economic challenges. This lesson is a key part of the Crypto Is FIRE (CFIRE) training plan, designed to deepen your understanding of Bitcoin's role in the financial landscape and its strategic value in building long-term wealth.
-
15Who is Satoshi NakamotoTrial 9 minutes
The mystery of Satoshi Nakamoto's identity is not just a curiosity—it's a cornerstone of Bitcoin's narrative. According to this lesson, the recent HBO documentary proposes new theories about Satoshi's identity, featuring prominent figures like Adam Back and Nick Szabo, who have long been rumored as potential candidates. These figures, known for their contributions to cryptography and early digital currency concepts, bring credibility but also controversy to the debate. The documentary's marketing has turned this age-old question into a viral conversation, but even if a name is proposed, true verification remains elusive. The documentary also addresses persistent FUD (Fear, Uncertainty, and Doubt) around theories that Bitcoin was created by government agencies like the CIA. While these claims are dismissed as lacking evidence, they underscore the enduring uncertainty surrounding Bitcoin's origins. As this lesson unfolds, it becomes clear that Satoshi’s story is less about the person and more about what Bitcoin represents—an alternative to centralized financial control and a symbol of digital financial sovereignty.
-
16The Bitcoin WhitepaperTrial 42 minutes
Bitcoin is more than just "digital money"; it’s a response to the inefficiencies and risks of traditional banking. The whitepaper opens with Satoshi’s assertion that Bitcoin can solve what he calls the "double-spending problem" without needing a trusted intermediary. He then explains Bitcoin's P2P network, the importance of cryptographic proof, and how miners—individuals or entities validating transactions—play a role in Bitcoin's decentralized security model. Through this design, transactions can be verified without relying on banks, and users maintain control over their funds via private keys. Nakamoto’s arguments provide a blueprint for a self-sustaining currency model, powered by incentives and consensus among network participants rather than centralized oversight. Each section of the whitepaper addresses a core component of this model, from transaction mechanics to mining incentives, bringing together technical rigor and an ideological stance on decentralization.
-
17BTC Lightning NetworkTrial 5 minutes
The Lightning Network is an off-chain layer-2 solution designed to enhance Bitcoin's transaction capabilities. As introduced, Bitcoin can only process about seven transactions per second, with fees reaching astronomical prices when the network is congested. A striking analogy is presented: consider paying a $50 fee to confirm a simple coffee purchase. In stark contrast, traditional financial networks like Visa boast capabilities of processing over 50,000 transactions per second at lower costs.
-
18Bitcoin After USA ElectionTrial 13 minutes
In this lesson, we'll delve into the emerging landscape of Bitcoin and its role in the evolving world of finance. The conversation led by Michael Saylor highlights the critical intersections of regulation, institutional acceptance, and investment strategies that underpin Bitcoin's ascent. As we explore these themes, we’ll draw parallels with traditional financial concepts, offering insights into why understanding Bitcoin is essential for anyone navigating the finance world today.
-
19Not Your Private Keys, Not your CryptoTrial 3 minutes
At its core, the lesson teaches us that control over your private keys equates to control over your assets. The argument revolves around the distinction between ownership and access, focusing on how traditional finance relies on intermediaries (banks) to manage funds, while cryptocurrency allows for complete individual control—if you know how to use it correctly.
Several strong points emerge throughout: the critical role of public and private keys, the inherent risks of custodial exchanges, and the lessons learned from the infamous Mt. Gox hack. The lesson goes beyond merely warning users to be cautious—it calls for full autonomy over one’s crypto. Examples like Robinhood’s refusal to provide wallet addresses serve as cautionary tales of the dangers posed by centralized exchanges.
In this lesson, the importance of self-custody is emphasized repeatedly: If you don’t control your private keys, you don’t own your crypto. With easy-to-use non-custodial wallets such as MetaMask and Ledger, the tools for reclaiming financial independence are at everyone’s fingertips—but only if they understand and respect the mechanics of private keys.

The lesson provides a fast-paced review of 50 cryptocurrencies, offering brief yet insightful snapshots of each one. The overarching theme is clear: cryptocurrencies are diverse, each bringing something unique to the financial table. From Bitcoin, the OG of digital money, to more niche players like Kusama, a test network for Polkadot, this spectrum highlights how innovation has taken many forms within blockchain technology. Some cryptos focus on privacy, like Monero, while others like Flow are building platforms for non-fungible tokens (NFTs). There’s also an examination of infrastructure, like Cosmos, which connects various blockchains together, and Polygon, a layer 2 solution aimed at making Ethereum faster and cheaper. The key argument is that while each cryptocurrency has its niche, they collectively represent the evolution of finance—one that is faster, decentralized, and more accessible.
-
22Critique of 50 cryptocurrenciesTrial 8 minutes
Roasting—critically, but humorously— 50 cryptocurrencies. The content sheds light on common misconceptions in the crypto space, particularly the overemphasis on market cap as an indicator of a coin’s potential. Through a series of witty critiques, the video illustrates the limitations and challenges of various crypto projects, from EOS’s jargon-filled website to IOTA’s never-ending promise of decentralization. The main thesis? While many investors are drawn to a project's size or ambition, they often overlook the real financial mechanisms—like liquidity—that determine success.
-
23What is a StablecoinTrial 12 minutes
Imagine holding a cryptocurrency that doesn’t swing wildly in value—one that stays as reliable as the dollar, yet offers all the flexibility and security of blockchain technology. Enter stablecoins, the digital assets pegged to traditional currencies like the U.S. dollar, which are transforming how we interact with crypto. With the unpredictable nature of cryptocurrencies like Bitcoin and Ethereum, stablecoins have emerged as a solution for investors seeking to leverage blockchain's benefits without getting burned by volatility.
In this lesson, we’ll dive into the world of stablecoins—an increasingly important tool in the financial toolkit. Not only are they used for trading, but stablecoins also have potential applications in decentralized finance (DeFi) and beyond. As you follow this lesson, you'll see how these digital assets play a crucial role in connecting traditional finance to the innovative world of cryptocurrencies. This is an essential part of your Crypto is FIRE (CFIRE) training plan, so let’s get started.
-
24What is TetherTrial 9 minutes
Tether, a stablecoin pegged to the U.S. dollar, was designed to provide a reliable bridge between traditional finance and the volatile crypto world. Theoretically, for every Tether (USDT) issued, there should be an equivalent U.S. dollar held in reserve by its parent company, Tether Limited. However, the company’s lack of transparency has led to significant skepticism. At its core, the argument revolves around whether Tether Limited has sufficient reserves to back the billions of USDT in circulation. Critics fear a scenario similar to a "bank run," where many users attempt to redeem their Tether for dollars simultaneously, only to find there isn't enough cash on hand. The video also touches on broader implications, such as Tether’s central role in the crypto ecosystem and the potential risk of a market collapse if confidence in USDT were to falter.
-
25Coins VS TokensTrial 12 minutes
In the world of cryptocurrencies, the terms "coins" and "tokens" are often used interchangeably, but they represent distinct concepts with unique roles in the blockchain ecosystem. Understanding the difference between coins and tokens is fundamental for anyone diving into the crypto space. This lesson will break down the core differences between coins and tokens, how each functions within the blockchain, and why recognizing these distinctions is crucial for your journey through the Crypto Is FIRE (CFIRE) training plan. By the end, you'll gain insights into how coins and tokens power the digital economy and their unique roles in traditional finance and decentralized applications.
-
26Why US Banned Gold How Applies to CryptoTrial 9 minutes
The lesson focuses on the 1933 U.S. gold confiscation under Executive Order 6102, a bold and controversial move by President Franklin D. Roosevelt in response to the Great Depression. Faced with an economic meltdown, the U.S. government sought to prevent gold hoarding, believing it was causing deflation and stagnation. By seizing private gold and raising its value by 75%, the government was able to print more money, effectively inflating the economy out of its dire state.
This story is not just a quirky historical fact; it reflects deeper economic strategies still in play today. Inflation, currency manipulation, and government control are still critical elements of modern financial systems. As we explore this case, we’ll also discuss its implications for cryptocurrency, where similar concerns about inflation and state control have made decentralized assets like Bitcoin increasingly popular.
-

28How a Blockchain WorksTrial 7 minutes
In this lesson, we explore the concept of blockchain using a relatable analogy: four friends splitting a dinner bill. It starts with a simple question—what if there were a better way to manage transactions without relying on banks? Blockchain offers a solution through a digital, decentralized ledger that records transactions securely. When friends like Jack, Ted, Sam, and Phil decide to split expenses, a blockchain records every transfer without the need for a third-party bank. Each transaction is recorded in a block, and each block is connected to the next, forming a chain that all participants can verify.
The video's key thesis is that blockchain technology solves many of the problems associated with traditional banking systems, like transaction delays, account hacking, and unnecessary fees. By using a decentralized ledger, blockchain ensures transparency and security, making it nearly impossible to alter records without consensus from the network. It’s this transparency and trust that have allowed cryptocurrencies to thrive. Throughout the lesson, examples like Bitcoin transactions and Walmart’s blockchain-enabled supply chain illustrate blockchain’s potential to revolutionize various industries.
-
29What is Proof of WorkTrial 9 minutes
In this lesson, we explore Proof of Work, a mechanism central to securing blockchains like Bitcoin. PoW ensures that all transactions are recorded accurately without the need for a central authority. By requiring “miners” to solve complex mathematical puzzles, PoW ensures consensus and prevents double-spending—where the same digital currency might be spent twice, undermining the system’s integrity. The video emphasizes the strengths of PoW, such as its transparency and security, while also highlighting significant challenges like its environmental impact and limited scalability. For example, it notes that in 2019, Bitcoin’s energy consumption rivaled that of Switzerland, sparking debates on the sustainability of PoW. The argument centers around whether the security benefits of PoW justify its resource intensity, a topic that remains relevant as more projects explore alternatives like Proof of Stake (PoS). Ultimately, the video underscores the crucial role PoW plays in the blockchain ecosystem while acknowledging its growing pains in an evolving market.
-
30What is Proof of StakeTrial 8 minutes
Proof of Stake (PoS) is a consensus mechanism that aims to reduce the energy consumption of blockchain networks by selecting validators based on the number of coins they have staked rather than their computing power. The video's key argument is that PoS presents a more efficient alternative to PoW, with its reduced energy needs and focus on penalizing bad actors through "slashing." It also highlights the transition of Ethereum to PoS, emphasizing how this shift could make the network more scalable while maintaining security.
One particularly striking claim made in the video is that PoS, by requiring participants to put their own funds at risk, aligns incentives more closely with network security. It contrasts this with PoW, where success is largely determined by computational power, leading to a concentration of resources among a few major players. While this argument makes a strong case for PoS as a democratizing force in the crypto world, the lesson also touches on potential risks, such as centralization in PoS systems and the risk of a 51% attack if stakes become too concentrated.
-
31But how does crypto actually work?Trial 25 minutes
At its core, Bitcoin is a digital ledger—a public record of transactions that is transparent and decentralized. Unlike traditional financial systems, where banks and governments maintain control over the flow of money, Bitcoin operates through a network of users who collectively verify and record transactions. The video lesson highlights this shift by guiding viewers through the step-by-step process of creating a secure, trustless system using cryptography. It begins with the concept of digital signatures, which ensure that only the rightful owner of a Bitcoin can authorize a transfer. From there, it introduces the idea of a decentralized ledger maintained through a process called "mining," where participants solve complex puzzles to validate transactions. The overarching argument is that Bitcoin, and by extension other cryptocurrencies, offers a new way of thinking about trust, money, and digital ownership in a world that increasingly questions centralized control.
