Day 3 — Bitcoin: what makes it valuable?
The Bitcoin code is open-source. Anyone can copy it. Hundreds of people have copied it. There are thousands of Bitcoin clones running on the internet right now, with names you've never heard, doing essentially the same thing the original does. None of them are worth anywhere close to what Bitcoin is worth. Most are worth nothing.
That is the first thing to understand about Bitcoin's value. It is not the technology by itself. The technology is freely available. What gives Bitcoin its value is everything that surrounds the technology: the history, the network, the energy spent securing it, the institutional capital that has slowly chosen to recognize it, and the deliberately enforced scarcity that nobody can change.
Let's take those one at a time.
Scarcity by design. Bitcoin is hard-capped at 21 million coins. That cap is written into the code, and changing it would require nearly every participant in the network to agree, which would never happen because every existing holder would be voting to dilute themselves. The cap is not a marketing claim. It is an enforced constraint baked into the protocol from day one. About 19.7 million coins have been mined so far. The last new bitcoin will be mined in roughly 2140. After that, there will never be a 21,000,001st coin. Ever.
That kind of scarcity does not exist in the traditional financial world. Every dollar can be created by the Federal Reserve in unlimited quantity. Every share of every public company can be issued in unlimited quantity by the company's board. Even gold, the traditional comparison, is technically unlimited (we just haven't found all of it yet, and we extract more every year). Bitcoin's 21 million cap is the first hard-capped asset humans have ever built. The macro investor Paul Tudor Jones called it "the fastest horse in the race against currency debasement." That is what he meant.
Network effect. Bitcoin is worth what it is worth because enough people decided it is. That sounds circular, but it is true of every form of money. Dollars are worth what they are worth because enough people accept them. Gold is worth what it is worth because enough cultures agreed it had value over thousands of years. Bitcoin compressed that adoption curve from millennia to about 15 years. The network effect is the thing every Bitcoin clone fails to overcome. A copy of the code with no holders, no exchanges, no miners, no merchants, and no narrative is just empty software.
Proof-of-work as energy backing. Bitcoin's security comes from the cost of attacking it. Right now the network is securing roughly $1.6 trillion in value with about $30 billion per year in energy and mining hardware expenditure. To rewrite Bitcoin's history, you would need to acquire and operate more compute than the entire rest of the network combined. The cost of doing that is in the hundreds of billions, sustained over time, and the moment you started attempting it, the network would respond. This is the unusual property of proof-of-work: the energy is not waste, it is the moat. Every kilowatt-hour spent mining is a kilowatt-hour an attacker would have to match to defeat the network.
The halving. Every four years, the reward miners receive for adding a new block to the chain is cut in half. This is called the halving, and it is encoded in the protocol. It happened in 2012, 2016, 2020, 2024, and will happen again in 2028. Each halving reduces the rate of new bitcoin entering circulation. The 2024 halving cut daily issuance from about 900 new bitcoin per day to about 450. Each one of these events tightens supply against whatever demand exists. Historically, the year following each halving has produced Bitcoin's largest price expansions. That is not a guarantee, and "past performance does not predict future results" is a real rule. But the pattern is worth understanding because it is one of the few hard, predictable supply-side dynamics in any financial asset.
Institutional adoption. As of 2026, the world's largest asset manager (BlackRock), the world's largest software treasury (Strategy, formerly MicroStrategy), several public companies, a handful of sovereign wealth funds, and a growing number of pension funds hold Bitcoin as a balance-sheet asset. Three years ago this would have been considered fringe. It is now mainstream. When BlackRock launches a Bitcoin product, gets approved by the SEC, and brings in tens of billions in inflows in under a year, the question of whether Bitcoin "counts" as a real asset is essentially settled at the institutional level. You can disagree with the trend. You cannot deny it.
Put all of this together and the case for Bitcoin's value becomes less about the technology and more about a thesis: a digitally native, hard-capped, network-effect-dominant asset, secured by enormous real-world energy expenditure, that institutional capital has now decided is worth holding alongside gold, treasuries, and equities. You can question every link in that chain. Plenty of smart people do. The point of this course is to give you the tools to evaluate it for yourself, not to convince you of a conclusion.
Tomorrow we look at the deceptively simple question: when you "own" Bitcoin, what do you actually own, and where is it stored? The answer is more interesting than most people realize, and it sets up the next four days of how the rest of crypto works.
Glossary
| Term | Definition |
|---|---|
| Scarcity (hard-capped) | A property of an asset where the maximum possible supply is fixed and cannot be changed. Bitcoin's 21 million cap is the canonical example. |
| Halving | The protocol-enforced event, occurring approximately every four years, that cuts the rate of new bitcoin entering circulation in half. Tightens supply against existing demand. |
| Network effect | The phenomenon where a network becomes more valuable as more people use it. Money, languages, and platforms all exhibit network effects. |
| Hash rate | The total computational power being applied to mining Bitcoin at any given time. Higher hash rate = more secure network. |
| Energy expenditure (as security) | The real-world cost of energy and hardware used to mine Bitcoin, which becomes the cost of attack for any party wanting to rewrite the chain. |
| Currency debasement | The loss of purchasing power of a currency over time, typically through inflation or increases in supply. The macro argument for Bitcoin rests heavily on this concept. |
Reality check
You are trying to explain to a smart friend why Bitcoin has value. They say, "But you can copy the code in an afternoon." What is the strongest version of your response?
If your answer starts and ends at "scarcity," you only have a third of the case. The full answer involves scarcity, network effect, energy security, and institutional recognition acting together. If you can describe how those four reinforce each other, you have the lesson.

1. Why does Bitcoin have value? by The Block
The cleanest one-page overview of the value thesis.
Read on IMPCT (curated commentary) | Read original (theblock.co)
Deven's take. Read this when you want a tight version of today's lesson. The Block does a good job of presenting the case without overselling it. Pay particular attention to the section on use-value: Bitcoin is being actively used as a settlement layer for billions of dollars in transactions per day, and that usage exists independently of price speculation. That usage is the part most skeptics underestimate.
2. How is Bitcoin scarce? by The Block
A focused look at the 21 million cap and the mechanics that enforce it.
Read on IMPCT (curated commentary) | Read original (theblock.co)
Deven's take. The reason this matters is not the headline number. It is that nobody can change it. There is no central party with the authority to issue more bitcoin. Compare that to the dollar: M2 money supply roughly tripled between 2008 and 2022. If you held cash through that period, you lost about two-thirds of your purchasing power against assets like real estate and equities. The argument for Bitcoin is not that it always goes up. The argument is that the supply side cannot be debased the way fiat can. That is a different claim than "it will go up." Hold both in your head.
3. What is the Bitcoin halving? by The Block
The four-year supply mechanic and what it has historically meant for price.
Read on IMPCT (curated commentary) | Read original (theblock.co)
Deven's take. The halving is the single most predictable supply-side event in any financial asset. We know the exact date of every future halving until 2140. Knowing the dates does not make the price predictable, but it does make the mechanics predictable. Every four years, the cost of producing new bitcoin doubles, the rate of new supply halves, and miners who are unprofitable at the old price are forced out unless the price rises. The system is engineered to put structural upward pressure on price every four years. Whether that pressure overwhelms whatever else is happening in macro is a separate question.
4. Bitcoin Is Hope by Lyn Alden
The single best macro argument for Bitcoin from a non-evangelist.
Read on IMPCT (curated commentary) | Read original (lynalden.com)
Deven's take. Lyn Alden is one of the few macro analysts I trust on this topic. She came to Bitcoin from a traditional finance background, not from crypto. She is unsentimental, data-driven, and unusually clear-eyed about the parts of the thesis that hold up versus the parts that don't. Read her work whenever you want to ground your understanding of Bitcoin in macroeconomics rather than internet enthusiasm. She is also a healthy counterweight to the people in crypto who think every coin is the next Bitcoin. She thinks most of them aren't.
5. The Bitcoin Standard by Saifedean Ammous (book recommendation)
The maximalist case for Bitcoin as a monetary asset.
Deven's take. Park this for later. It is a long book and intentionally one-sided. It will tell you why Bitcoin is the only crypto that matters and dismiss everything else. That is a partial view, and you should hold it alongside other perspectives. But the historical framing of money is genuinely valuable, and you should know how the Bitcoin-only camp argues their case if you're going to be conversant in this space.
Tomorrow
We pivot from the macro question (why does Bitcoin have value) to the practical one (where is your bitcoin actually stored, and how do you keep it safe). The answer rewires how most people think about the word "wallet."
See you in the morning.
