Bitcoin ₿

I get asked about Bitcoin a lot, so here's the primer I share with friends: where money came from, what makes money good, how Bitcoin works, how to get started, and the best stuff to watch and read if you want to go deeper.

First principles of Bitcoin

In a truly free market, where participants are allowed to choose, the best money naturally emerges over time.
Money is a tool for moving value across time and space. The better it holds value, the better it does both.
The hardest money wins. Money that is costly to produce and hard to inflate keeps its value; everything else gets debased.
Whoever can create money at will taxes everyone who holds it. Inflation quietly transfers wealth from savers to the issuer.
Money is a social consensus: a shared ledger of who is owed what.
Bitcoin’s 21 million supply cap is enforced by code and by every node that runs it, not by anyone’s promise.
Don’t trust, verify. Anyone can check the rules and the entire ledger for themselves.
Not your keys, not your coins. If someone else holds your keys, you hold an IOU.
Proof of work ties digital money to real-world energy. Creating a new block has a real cost that can’t be faked.
Decentralization is what makes the rules credible. No single party can change them.
A ledger anyone can join without permission is neutral. It doesn’t care who you are or where you live.
Money that can’t be censored or seized protects the people who need it most.
Sound money lowers time preference. When savings hold their value, people save more and think long term.

A brief history of money

Barter. Direct exchange of goods and services. Inefficient, not divisible, hard to store value.
Commodity money. Gold, silver, shells, tobacco, cigarettes, beans, pelts. Intrinsic value and widely accepted, but heavy, hard to divide and not always portable.
Paper money. Introduced as receipts for gold. Lightweight and easier to trade, but requires trust in the issuer.
Fiat money. Government-issued money with no intrinsic value (e.g., USD). Convenient and widely accepted, but unlimited supply means inflation, debasement and dilution, and trust breaks down in crises.
Digital fiat money. Bank transfers, credit cards, mobile payments. Instant and global, but centralized control, privacy concerns, and governments can still print and debase.

Characteristics of perfect money

Scarcity: limited supply to retain value over time.
Durability: long-lasting and resistant to wear.
Divisibility: easily split into smaller units.
Portability: easy to carry and transfer globally.
Fungibility: each unit is identical and interchangeable.
Security: resistant to counterfeiting and theft.
Decentralization: no central authority controlling issuance or value.
Global accessibility: usable by anyone, anywhere, without intermediaries.

Bitcoin vs. gold vs. USD

	Bitcoin	Gold	USD
Scarcity	✅ Fixed supply (21M)	✅ Limited by nature	❌ Unlimited (inflationary)
Durability	✅ Digital, can't degrade	✅ Durable, can wear	✅ Durable paper/plastic
Divisibility	✅ 100M satoshis per coin	❌ Hard to divide	✅ To the cent
Portability	✅ Global via the internet	❌ Heavy in quantity	✅ Physical and digital
Fungibility	⚠️ Traceable; tainted coins	✅ By weight/purity	✅ Interchangeable
Security	✅ Decentralized + cryptography	✅ Can't counterfeit; can be stolen	❌ Counterfeiting, inflation
Decentralization	✅ No central authority	✅ Naturally occurring	❌ Central banks
Global access	⚠️ Needs internet and know-how; fees vary	❌ Not easily accessible	✅ Widely accepted

Bitcoin basics

What is Bitcoin?

An ideology, a protocol, a network, and a digital commodity.
Best thought of as "digital gold" and a store of value.
A decentralized network not controlled by governments, corporations or banks. Open source, no governing body, no issuer.
Limited supply: only 21 million coins, mined by the year 2140 (about 19.9M exist today).
Created by Satoshi Nakamoto, an anonymous creator who has since disappeared and was clearly extremely well versed in cryptography, economics, mathematics and operational security.

How does it work?

Transactions are recorded on a public ledger called the blockchain (or timechain).
Miners and nodes validate transactions and secure the network, earning new coins and transaction fees.
You store bitcoin in wallets using private and public keys.
The network is millions of times more powerful than the world's best supercomputer, with 10,000x more computing power than all of Google.

Why is it valuable?

Scarcity: the 21 million cap makes it a strong store of value.
Fast, low-cost global transactions (about 10 minutes to full confirmation and settlement).
Secure, with no reliance on intermediaries.
Cost of production: mining takes serious computing power, electricity and specialized equipment, much like mining gold, which acts as a kind of price floor. Energy and compute tie Bitcoin to the laws of physics and the real world.

What are the risks?

Price is volatile measured in USD, though it's expected to become less volatile as it matures with each 4-year halving cycle.
Wallets and private keys must be kept secure: "Not your keys, not your coins."
Some countries regulate or restrict it, since it threatens government control of money.

How to get started

Ways to use Bitcoin

Buy it on an exchange (Coinbase, Gemini, Strike) or earn it by mining.
Buy it through ETFs (BlackRock, Fidelity, Grayscale, Franklin Templeton, etc.).
Store it in a digital wallet (hot or cold).
Spend it with merchants or send it anywhere in the world.
The Lightning "Layer 2" network is emerging for instant payments.

Next steps and self-custody

Create a Strike or Coinbase account and buy some bitcoin.
Set up a non-custodial wallet (e.g., BlueWallet).
Send bitcoin to, and from, your non-custodial wallet.
Store your seed words somewhere safe!
