Frequently Asked Questions

Bitcoin is digital money that no one controls. Unlike dollars or euros, which are managed by governments and banks, Bitcoin runs on a global network of computers following the same rules.

Key properties:

• Limited supply: Only 21 million will ever exist (like digital gold)
• Decentralized: No company or government runs it
• Borderless: Send it anywhere in the world, 24/7
• Permissionless: Anyone can use it without approval

Think of it as the internet's native money, built for the digital age.

Yes. Bitcoin functions as money because people agree it has value. The same reason dollars, gold, or any other money works.

Bitcoin meets the classic criteria for money:

• Store of value: People save in it (like gold)
• Medium of exchange: You can buy things with it
• Unit of account: Prices can be denominated in it

El Salvador made it legal tender in 2021. Major companies accept it. Wall Street now trades Bitcoin ETFs. Whether you call it "real" money is philosophical, but billions of dollars of value suggest people treat it as such.

Bitcoin is the original cryptocurrency, created in 2009 by an anonymous person/group called Satoshi Nakamoto. It was designed specifically to be sound money, scarce, decentralized, and censorship-resistant.

"Crypto" refers to thousands of other digital assets that came after Bitcoin. Most are fundamentally different:

• Many have companies or foundations controlling them
• Most don't have a fixed supply cap
• Many are designed for different purposes (smart contracts, tokens, etc.)
• Some are outright scams

This course focuses on Bitcoin specifically because its properties (true decentralization, fixed supply, longest track record) make it uniquely suited as a savings technology.

Bitcoin was created by Satoshi Nakamoto: a pseudonym for an unknown person or group. Satoshi published the Bitcoin whitepaper in October 2008 and launched the network in January 2009.

Satoshi communicated only through forums and email, then disappeared in 2011, never revealing their identity and never spending their estimated 1 million+ Bitcoin (worth tens of billions today).

Bitcoin has value for the same reason anything has value: people want it. But there are specific properties that drive demand:

• Scarcity: Only 21 million will ever exist, and ~4 million are already lost forever
• Utility: It can be sent anywhere instantly, stored without a bank, and can't be seized or frozen
• Network effect: The more people use it, the more useful it becomes
• Cost of production: Mining requires real energy and resources
• Credibility: 15+ years of operation without being hacked or inflated

Gold doesn't have "intrinsic" value either, we just collectively agree it's valuable because it's scarce and has useful properties. Bitcoin is the same, but with better portability, divisibility, and verifiability.

People have asked this at every price point since $1. Here's perspective:

• At $100: "Too late, I missed the boat"
• At $1,000: "Too late, it's already exploded"
• At $10,000: "Too late, the opportunity is gone"
• At $60,000: "Too late..." (you get the idea)

The question isn't "is it too late?" but rather: "Do you believe Bitcoin will be worth more in 5-10 years than today?"

Consider:

• Only ~2-5% of the world owns any Bitcoin
• Spot ETFs just launched in 2024, institutional adoption is early
• Governments continue printing money (Bitcoin's core thesis)
• 21 million supply cap never changes

Absolutely! This is one of the most common misconceptions. You don't need to buy a whole Bitcoin.

Bitcoin is divisible to 8 decimal places. The smallest unit is called a satoshi (or "sat"):

• 1 Bitcoin = 100,000,000 satoshis
• You can buy as little as $1 worth
• Most people own fractions of a Bitcoin

Think of it like buying gold by the gram instead of by the bar. Start with whatever amount you're comfortable with.

Only invest what you can afford to lose or not touch for 5+ years. Bitcoin is volatile. It can drop 50%+ before recovering to new highs.

General guidelines (not financial advice):

• Have an emergency fund first (3-6 months expenses)
• Pay off high-interest debt
• Start small, $20-100 just to learn
• Many suggest 1-10% of investment portfolio for Bitcoin exposure

The best approach: Dollar Cost Average (DCA): buy a fixed amount regularly regardless of price. This removes emotion and smooths out volatility.

Both give you Bitcoin exposure, but with important differences:

Spot Bitcoin ETFs (IBIT, FBTC, etc.):

• ✅ Easy to buy in brokerage/retirement accounts
• ✅ Familiar, regulated structure
• ✅ No wallet management
• ❌ Annual fees (0.2-0.5%)
• ❌ You don't actually own Bitcoin. You own shares
• ❌ Can't withdraw to your own wallet
• ❌ Subject to market hours

Actual Bitcoin:

• ✅ You own it directly, "not your keys, not your coins"
• ✅ Can self-custody for maximum security
• ✅ 24/7 access, no market hours
• ✅ Can use it (Lightning payments, etc.)
• ❌ Requires learning wallet security
• ❌ Not available in retirement accounts (usually)

This depends entirely on your goals. Many long-term holders don't plan to sell. They plan to spend or borrow against it eventually.

Reasons some people sell:

• Life event requiring cash (home purchase, emergency)
• Reached a specific financial goal
• Rebalancing a portfolio
• Taking some profits while keeping core position

The "never sell" perspective:

• Bitcoin may continue appreciating against fiat currencies
• Selling triggers taxes; borrowing against it may not
• Difficulty "timing" the market, many sell too early
• Long-term holders have historically been rewarded

If you have your seed phrase backed up, losing your phone is no problem. Your Bitcoin isn't stored on your phone. It's on the blockchain. Your phone just holds the keys to access it.

Recovery process:

1. Get a new phone
2. Download your wallet app
3. Select "Restore wallet"
4. Enter your 12 or 24 word seed phrase
5. Your Bitcoin reappears

A seed phrase (also called recovery phrase) is a set of 12 or 24 random words that can restore your entire Bitcoin wallet. It's generated when you create a wallet.

Example:

Why it's critical:

• These words = your Bitcoin. Anyone with them controls your funds.
• They can restore your wallet on any compatible device
• If you lose them and your device, your Bitcoin is gone forever
• There's no "forgot password". Bitcoin has no customer support

Security rules:

• ✅ Write on paper, store securely (fireproof safe, safety deposit box)
• ✅ Consider stamping on metal for fire/water resistance
• ❌ Never store digitally (no photos, no cloud, no email)
• ❌ Never share with anyone, not even "support"

For small amounts, reputable exchanges are reasonably safe. For larger amounts, self-custody is strongly recommended.

Exchange risks:

• Exchange hacks: Mt. Gox, FTX, and others lost billions in customer funds
• Bankruptcy: If the exchange fails, you may lose everything
• Frozen accounts: Exchanges can freeze your account for various reasons
• Not your keys: The exchange controls the Bitcoin, not you

General guidelines:

• Under $1,000: Exchange is probably fine
• $1,000-$10,000: Consider a hardware wallet
• $10,000+: Strongly consider self-custody
• Significant savings: Definitely self-custody with robust backup

For long-term storage, a hardware wallet with proper seed phrase backup is the gold standard.

Recommended setup:

1. Hardware wallet (Ledger, Trezor, Coldcard), ~$70-150
2. Metal seed backup (Cryptosteel, Billfodl), ~$30-60
3. Secure storage for seed phrase (fireproof safe, safety deposit box)
4. Consider geographic distribution: backup in separate location

Advanced options:

• Multisig: Require 2 of 3 keys to spend (more security, more complexity)
• Passphrase: Extra word added to seed phrase (plausible deniability)

Start simple. A hardware wallet + written seed phrase in a safe place is sufficient for most people.

The Bitcoin network itself has never been hacked in 15+ years of operation. The cryptography and consensus mechanism are extremely robust.

What HAS been hacked:

• Exchanges: Mt. Gox, Bitfinex, FTX (not Bitcoin itself)
• Individual wallets: Through phishing, malware, or poor security
• Smart contracts: On other blockchains, not Bitcoin

To "hack" Bitcoin itself, you'd need to:

• Control 51%+ of global mining power (costs billions)
• Break SHA-256 encryption (not currently possible)
• Coordinate attack across 50,000+ nodes globally

Quantum computers theoretically could break Bitcoin's cryptography someday. But this concern is often overstated.

Reality check:

• Current quantum computers can't break Bitcoin encryption
• Experts estimate 10-20+ years before this might be possible
• Quantum computers would break all internet security first (banks, military, everything)
• Bitcoin can upgrade to quantum-resistant algorithms when needed

What Bitcoin developers are doing:

• Researching quantum-resistant signature schemes
• Taproot upgrade provides some forward protection
• The threat is known and actively monitored

Bitcoin's base layer prioritizes security and decentralization over speed. This is a deliberate design choice.

Base layer (on-chain):

• ~7 transactions per second
• 10-minute average block time
• Fees vary ($0.50 to $50+ during high demand)
• Best for large, important transactions

Lightning Network (Layer 2):

• Millions of transactions per second possible
• Millisecond settlement
• Fees under $0.01
• Perfect for everyday payments

Most "slow and expensive" complaints ignore Lightning, which already handles millions of transactions daily.

The last Bitcoin will be mined around the year 2140. After that, miners will earn only transaction fees. No new Bitcoin created.

Why this isn't a problem:

• We have 100+ years to prepare
• Transaction fees already contribute to miner revenue
• As Bitcoin's value increases, fees become more valuable
• The network self-adjusts (fewer miners = lower difficulty = remaining miners stay profitable)

Current trajectory:

• 2024: Mining reward is 3.125 BTC per block
• 2028: Drops to 1.5625 BTC
• Each halving reduces new supply while (historically) price increases

The gradual transition over 100+ years gives the ecosystem plenty of time to adapt. This is by design.

Bitcoin uses significant energy, about 150 TWh/year. Whether this is "bad" depends on perspective.

Context matters:

• Global banking system: ~260 TWh/year
• Gold mining: ~240 TWh/year
• Christmas lights in USA: ~6 TWh/year
• Always-on devices (standby): ~35 TWh/year

Arguments in Bitcoin's favor:

• ~50-60% of mining uses renewable energy (higher than most industries)
• Miners seek cheapest energy, often stranded renewables that would be wasted
• Mining can monetize flared natural gas (reducing methane emissions)
• Energy use = security; it's a feature, not a bug

Some governments have tried to ban Bitcoin (China, Nigeria). Here's what happened: people kept using it anyway.

Why bans don't work well:

• Bitcoin is software. You can't ban math
• Peer-to-peer trading continues underground
• VPNs and privacy tools bypass restrictions
• People in banned countries often need Bitcoin most (capital controls, currency collapse)

The trend is actually the opposite:

• El Salvador made Bitcoin legal tender
• US approved spot Bitcoin ETFs
• Major banks now offer Bitcoin services
• Politicians increasingly support Bitcoin

Yes, some criminals use Bitcoin. Criminals also use cars, phones, cash, and the internet. Tools can be misused.

Reality check:

• Cash is still the dominant currency for crime
• Bitcoin is actually terrible for crime. Every transaction is permanently recorded
• Blockchain analysis companies help law enforcement track criminals
• Major criminal busts have happened because Bitcoin is traceable

Statistics:

• Chainalysis estimates <1% of Bitcoin transactions are illicit
• UN estimates 2-5% of global GDP is laundered via traditional banking
• Bitcoin is more traceable than cash, not less

No. A Ponzi scheme requires a central operator paying old investors with new investor money. Bitcoin has:

• No central operator or company
• No promised returns
• Open-source code anyone can verify
• Transparent supply and rules
• 15+ year track record

What Bitcoin IS:

• A decentralized network with fixed monetary policy
• A speculative asset with high volatility
• A technology, not an investment scheme

Important distinction: While Bitcoin itself isn't a scam, there are many scams in the Bitcoin/crypto space. Fake exchanges, Ponzi schemes using Bitcoin, and fraudulent projects exist. That's why education matters.

Bitcoin is volatile because it's a new, growing asset being priced in real-time by a global market. Several factors contribute:

• Still relatively small: ~$1 trillion market cap vs. $100+ trillion in global assets
• 24/7 trading: No market hours, no circuit breakers
• Emotional asset: Attracts both conviction holders and speculators
• Leverage: Traders using borrowed money amplify moves
• News sensitivity: Regulatory news, hacks, celebrity tweets all move markets

Historical perspective:

• Amazon stock dropped 95% in 2000-2001
• Apple dropped 80% in 1997-1998
• New technologies are always volatile before maturing

In most countries, yes. Bitcoin is typically treated as property, meaning you may owe taxes when you sell, trade, or spend it.

Common taxable events (varies by country):

• Selling Bitcoin for cash
• Trading Bitcoin for another cryptocurrency
• Buying goods/services with Bitcoin
• Receiving Bitcoin as payment for work

Generally NOT taxable:

• Buying Bitcoin with cash (no gain yet)
• Transferring between your own wallets
• Giving Bitcoin as a gift (recipient may owe later)
• Holding without selling

In most of the world, yes. The legal status varies:

Legal and regulated:

• United States, Canada, European Union
• United Kingdom, Australia, Japan
• Most of South America, Africa, Asia

Legal tender:

• El Salvador (2021)
• Central African Republic (2022)

Restricted or banned:

• China (mining and trading banned, holding ambiguous)
• A few other countries with varying enforcement

Check your local laws, but for most readers, Bitcoin is fully legal to buy, hold, and sell.

If no one knows how to access your Bitcoin, it's lost forever. Unlike bank accounts, there's no institution to contact.

Inheritance planning options:

• Seed phrase in a will/safety deposit box: Simple but has privacy tradeoffs
• Trusted family member: Teach them how wallets work, share location of backup
• Lawyer or estate attorney: Include crypto instructions in estate planning
• Multisig setup: Require 2 of 3 keys (you + spouse + lawyer, for example)
• Specialized services: Casa, Unchained offer inheritance solutions
