This Absurd Rap Battle Brilliantly Summarizes the Complex Debate Over Cryptocurrency
In a wildly creative and entertaining video, the YouTube channel Meme Money has staged an epic rap battle between two historical figures representing the past and future of money: Alexander Hamilton and Satoshi Nakamoto.
The six-minute video features Hamilton, one of America‘s Founding Fathers and the first U.S. Secretary of the Treasury, going head-to-head with Nakamoto, the mysterious creator (or creators) of Bitcoin, in a lyrical showdown over the merits of centralized fiat currency versus decentralized cryptocurrency.
While undoubtedly silly and satirical, the rap cleverly surfaces many of the core issues and arguments in the very real, ongoing debate over the role cryptocurrency should play in the global financial system. Let‘s unpack some of the key points made by each character and explore the bigger picture of centralized versus decentralized money.
A Primer on Centralized and Decentralized Currency
To understand the context of the rap battle, it‘s helpful to review some monetary history. For most of the past century, the world has operated on centralized, government-backed fiat currencies, with central banks like the U.S. Federal Reserve controlling the money supply and setting monetary policies. Fiat money is declared legal tender by decree, but is not backed by any physical commodity like the gold standard that preceded it.
This centralized currency system gives governments and banks tremendous power and is the backdrop against which Bitcoin emerged in 2008 as the first decentralized cryptocurrency. Instead of relying on financial institutions, Bitcoin runs on a peer-to-peer network of computers worldwide and uses cryptography to control the creation of new units and to verify transactions. Anyone can participate in the open-source Bitcoin network; it is not controlled by any single authority.
How Bitcoin and Blockchain Technology Work
At a technical level, Bitcoin is powered by a distributed database technology called blockchain. A blockchain is essentially a ledger of transactions that is shared across a network of computers. When a new Bitcoin transaction occurs, it is broadcast to the entire network. Computers on the network (called "nodes") then verify the transaction using complex cryptographic algorithms.
Once a transaction is verified, it is combined with other transactions into a "block" and permanently added to the blockchain. Each block is cryptographically linked to the previous block, creating an unbroken chain that stretches back to the very first Bitcoin transaction. This decentralized structure makes the blockchain highly resistant to tampering or revision.
The process of verifying transactions and adding new blocks to the blockchain is called mining. Bitcoin miners use specialized hardware to solve complex mathematical puzzles. When a miner solves a puzzle, they are rewarded with newly minted Bitcoins and any transaction fees. This mining process serves the dual function of securing the network and gradually increasing the Bitcoin money supply over time.
While Bitcoin was the first and remains the largest cryptocurrency, in the years since its launch, thousands of other cryptocurrencies have proliferated. Many of these, like Ethereum, add additional features and functionality beyond simple value transfer. Ethereum, for example, supports smart contracts – self-executing contracts with the terms directly written into code.
Competing Visions for the Future of Money
Against this technical backdrop, the rap battle personifies two competing visions for the future of the financial system. On one side is the status quo of government fiat money that has prevailed for the past century. On the other is the radical new model of decentralized cryptocurrency that has emerged over the past decade.
Hamilton‘s Case for Centralized Currency Control
Arguing the centralized side is Hamilton (portrayed by EpicLloyd), who established America‘s early financial system and central bank. "Without a strong central government," he raps, a "nation‘s unlikely to survive."
Hamilton asserts the need for centralized control and regulation to mitigate risks like hacks, scams, accidental losses, and illicit usage that plague cryptocurrency. "If our central database gets hacked, insurance will make a case to get your money back," he points out. "Cause in fact, it‘s tracked, and money leaves a trail. Central currency is strong, cryptocurrency is frail."
He also argues crypto has limited real-world use today ("Can‘t bitcoin the dentist, can‘t bitcoin my breakfast") and that the speculative investing around "irrational" crypto assets like Dogecoin is unsustainable and will "all gonna crash."
Perhaps most damningly, Hamilton highlights the immense energy consumption required to power the Bitcoin network: "The only change you‘re making is climate change. Power grids spiking all across the land. Overheated, no one needs it, hope it all is banned."
Nakamoto‘s Vision for a Decentralized Financial Future
On the decentralized side, Nakamoto (played by Timothy DeLaGhetto) makes the case that cryptocurrency represents a liberating financial force and an important counterweight to centralized control. He argues the current fiat system has made the "rich get richer" while underserving the broader population: "A buncha rich white guys made this system. Why would they ever change this? When it‘s made them rich men!"
In contrast, Nakamoto asserts, crypto is a "true global currency" that can expand financial access to "billions of people [who] don‘t have bank accounts" as well as provide "censorship resistance for those who need it urgently." As he puts it, "Crypto has no borders…freedom to the people was my ultimate goal."
While acknowledging that most crypto usage today is not yet for ordinary payments and purchases, Nakamoto suggests this will change over time as adoption grows: "No currency starts with universal adoption; it takes time for places to make it an option."
Cryptocurrency Adoption and Market Dynamics
Cryptocurrency adoption has grown significantly since Bitcoin‘s genesis block was mined in 2009, but it still represents a tiny fraction of global financial activity. As of 2023, the total market capitalization of all cryptocurrencies is around $1.2 trillion, compared to over $100 trillion in global fiat money supply (M2).
That said, crypto has seen explosive growth in trading volumes, peaking at over $90 billion per day in late 2022. Major financial institutions and corporations like Tesla, Square, and Goldman Sachs have added Bitcoin to their balance sheets, lending credibility to its status as an investable asset class.
One way to visualize the rapid growth of cryptocurrency is to look at the number of distinct cryptocurrencies that have been created over time:
Year | Number of Cryptocurrencies |
---|---|
2013 | 66 |
2014 | 506 |
2015 | 795 |
2016 | 1112 |
2017 | 1335 |
2018 | 2102 |
2019 | 2453 |
2020 | 4150 |
2021 | 7888 |
2022 | 10127 |

Interestingly, while the number of cryptocurrencies has proliferated, Bitcoin has maintained a dominant market share, as seen in this snapshot from April 2023:
Coin | Market Cap | Market Share |
---|---|---|
Bitcoin | $548 billion | 49.4% |
Ethereum | $204 billion | 18.4% |
Binance Coin | $45 billion | 4.1% |
Others | $311 billion | 28.1% |

Technical Challenges and Scaling Solutions
Despite this growth, cryptocurrency faces significant technical challenges that limit its ability to function as a global payment system. Chief among these is the issue of scalability. Because of the way Bitcoin‘s proof-of-work consensus mechanism is designed, the network can only process around 5-7 transactions per second. By comparison, credit card networks like Visa can handle tens of thousands of transactions per second.
This throughput bottleneck leads to network congestion, high transaction fees and long confirmation times during periods of peak demand. If cryptocurrency is to compete with mainstream payment rails, it will need to increase its transaction capacity by orders of magnitude.
Developers are pursing a variety of approaches to scale blockchain networks, including:
- Increasing block sizes to fit more transactions per block
- Using sharding to split blockchain state across parallel subchains
- Employing off-chain transaction layers like the Bitcoin Lightning Network
- Experimenting with alternative consensus mechanisms like proof-of-stake
Ethereum, the second-largest cryptocurrency, is in the midst of a multi-year transition to Ethereum 2.0, which will replace proof-of-work mining with a more energy-efficient proof-of-stake system and introduce sharding to radically increase transaction throughput.
The Energy and Environmental Impact of Cryptocurrency
Another major challenge facing cryptocurrency is its energy footprint and environmental impact. Because proof-of-work mining is an intentionally costly process designed to secure decentralized networks in the absence of trusted intermediaries, it consumes vast amounts of electricity.
According to the Cambridge Bitcoin Electricity Consumption Index, as of May 2023, the estimated annualized electricity consumption of the Bitcoin network is around 141 terawatt-hours, which is comparable to the power consumption of a country like Argentina or Norway.
This has led to concerns about cryptocurrency‘s carbon footprint and potential to exacerbate climate change, particularly given that much mining activity occurs in regions with coal-heavy power grids like China. A 2021 study estimated that Bitcoin‘s annual carbon emissions are comparable to a small country like Sri Lanka.
Defenders of proof-of-work argue this energy expenditure is justified to secure a decentralized monetary network and that Bitcoin incentivizes renewable energy development by providing a constant demand for cheap power. But the optics of Bitcoin‘s power consumption remains a challenge, particularly as more energy efficient alternatives like proof-of-stake emerge.
Looking Forward: The Evolution of Cryptocurrency
As digital assets evolve, we are likely to see continued experimentation with new consensus models, governance structures, and use cases beyond simple value transfer. Smart contract platforms like Ethereum aim to use cryptocurrency as a foundation for decentralized applications (dapps) and financial primitives that could one day form an open, global, and permissionless economic layer.
Just as the static web pages of the 1990s evolved into the dynamic, interactive web applications we use today, cryptocurrency networks may serve as the base layer for future decentralized applications that we can hardly envision today. This could include everything from decentralized social networks and content platforms to self-sovereign identity solutions and liquid democratic governance.
Chris Dixon, a general partner at venture firm Andreessen Horowitz, has compared this evolution to the "oil and gas" phase of the early internet:
"The first 15 years of the web were pretty boring from a commercial point of view. There were a few niche commerce apps like buying books…In the year 2000, if you had said we‘re going to build a search engine and give away all the results for free, people would think that sounds crazy. But then Google turns out to be an enormous company. The point is, it took a while for people to figure out the business model."
In the near term, we are likely to see continued development of DeFi (decentralized finance) applications that aim to replicate traditional financial services like lending, borrowing, and trading in a decentralized context. According to data aggregator DeFi Llama, the total value locked in DeFi protocols grew from less than $1 billion in May 2020 to over $50 billion by May 2023.
Conclusion: The Significance of the Crypto Debate
Ultimately, the rap battle between Hamilton and Nakamoto is about more than just the technical and economic tradeoffs between fiat and cryptocurrency. It‘s a debate about power, control, and the very architecture of money in a digital age.
At its core, cryptocurrency poses a fundamental challenge to the nation-state‘s monopoly over money. For centuries, governments have used control over currency as a powerful policy tool and lever of power. The rise of decentralized, stateless money represents a profound shift that has only begun to play out.
Whether cryptocurrency can overcome its technical and regulatory hurdles to truly rival fiat money remains an open question. But even if it falls short of that ultimate goal, the crypto movement has unleashed a wave of permissionless innovation in money and finance that will have far-reaching consequences.
By dramatizing this debate in the form of a rap battle, Meme Money has found a uniquely entertaining way to unpack the key arguments and capture the revolutionary spirit driving the cryptocurrency space forward. As we continue to explore the uncharted territory between fiat and crypto, channeling the wit and vision of figures like Hamilton and Nakamoto can help light the way.
