Dad: Son, what about newer versions of Bitcoin like Bitcoin Cash and BitcoinSV?
Son: Nah, Dad. Those are shitcoins!
Bitcoin Core 25.0, Bitcoin Core 24.1 Bitcoin Core 23.2, Bitcoin Core 23.1, Bitcoin Core 22.1, … These are newer Versions of Bitcoin.
There are other Bitcoin Core alternatives like "Bitcoin Knots", "Libbitcoin" and "BitcoinJ" that don’t fork the blockchain.
Dad: How that?
Son: Satoshi launched the first Bitcoin client in January 2009. Over time, developers improved it, leading to "Bitcoin Core." Other projects also created compatible Bitcoin versions with the same consensus rules and protocols.

Dad: Son, what is the difference between a Bitcoin address and a Bitcoin public key?
Son: Hi Dad,
That's a good question! An address represents a hash of a public key of an asymmetric key pair.
The owner of the key pair can use the private key to sign transactions or messages.
Dad: Why sign a message?
Son: For example, to prove ownership of an address.
Only by using the correct private key a valid signature may be created, which then anyone can verify as valid by using the associated address which, again, represents the public key.

You're talking about the "Opendime", I assume. A cheap, private and fast transaction medium, especially when fees go up.
Dad: Yes! Never underestimate an Opendime.

Dad: Son, what is "Hyperbitcoinization"?
Son: Hi Dad,
"Hyperbitcoinization is a voluntary transition from an inferior currency to a superior one, and its adoption is a series of individual acts of entrepreneurship rather than a single monopolist that games the system."
It's from the "Hyperbitcoinization" article written by Daniel Krawisz back in 2014. You can read it in full length and for free on the "Satoshi Nakamoto Institute" website.
Dad: Thank you, will add it to my reading list.
Son: The "Satoshi Nakamoto Institute" has published numerous other articles. Here is the link, https://nakamotoinstitute.org.

Dad: Son, what do you mean by "stacking sats" exactly?
Son: Hi Dad,
To me, "stacking sats" is the act of converting an inferior asset into a superior one, namely bitcoin.
Because stacking sats is done often and mostly on a regular basis, this result is a fraction of a bitcoin, measured in "sats".
One bitcoin can be divided into 100,000,000 Satoshis, or "sats" for short.
Dad: Son, let us stack some sats together!

Son: Hi Dad,
The bitcoin markets are unpredictable.
Few are able to consistently turn a profit, particularly during a bear market, much less code a program to do so.
Dad: So, that is a taboo?
Son: Anything or anyone claiming guaranteed profits or insider knowledge should be treated as scam or scammer, uhm, with caution.

Son: Hi Dad,
Yes, of course they do.
Bitcoin is the best and hardest money ever.
However, the percentage of bitcoins used for crime is small compared to US dollars.
Dad: Hmm... Your counterargument makes these "facts" seem like an attack on Bitcoin.
Son: Bitcoin is black market money. Few.

The bag is really special. Pretty sure it has more security feature than a banknote.
Son: Hi Dad,
Not sure about that one. ;-)
But yes, the device seems well protected. However, I recommend you download the latest firmware from Coinkite, check it and install it on your Coldcard manually. And also inspect the device visually, and verify the bag number.
Dad: Son, why all the effort, it is "just a calculator".
Son: Haha. Anyway, I will send you a tutorial later.

Son: Dad, here's the four-point plan to not screw up with your bitcoin.
1. Never store a 12/24 recovery seed words online, not even encrypted
2. Never type a 12/24 recovery seed words onto any online device
3. Only enter the 12/24 recovery seed words directly onto a hardware wallet
4. Only record the 12/24 recovery seed words onto durable physical medium such as a Cryptosteel Capsule or a Cryptosteel Cassette.
Dad: Son, sounds like a plan.

Dad: Son, why do you believe some individuals are reluctant to delve into the realm of Bitcoin?
Son: Hi Dad,
Common obstacles to Bitcoin include a general apprehension towards new technology, experiences of being deceived by unreliable shitcoins and their promoters.
Another major concern is the question, "If it's so beneficial, why isn't everyone already using it?"
Dad: I see...
Son: Breaking down these barriers often hinges on establishing personal trust. Dad, consider delving into more Bitcoin discussions with your boomer friends! ;)

Dad: Son, what is this again?
Son: Dad, this is just a random, 256-bit hexadecimal number. A bitcoin private key.
A private key is used to spend bitcoin and as the source of its public key. The public key is required to receive bitcoin.
Dad: Are public keys the same thing as addresses?
Son: No. Bitcoin addresses are derived from a public key using a one-way function. Or in other words:
A bitcoin address is a hashed version of a public key. It’s shorter than the original public key.

Dad: Son, why does it take so long to have my new Umbrel ready to use? It is syncing since hours now.
Son: Dad, again, it's a question of time preference.
A full node, what your Umbrel is, is a program that fully validates transactions and blocks.
Everything from the Genesis block to today's latest block must be downloaded and validated first. This is the only way to be sure that you have a valid copy of the blockchain running.
Dad: Ok, I see. How can this be accelerated?
Son: A fast internet connection and a fast SSD disk helps to speed up the initial sync, however ...
You'll have to be patient, Dad. ;-)

Dad: Son, is there a difference between Bitcoin and bitcoin (upper-/lowercase 'b')? I have seen both spellings in publications.
Son: Hi Dad,
When expressed using a small 'b', the word bitcoin usually refers to the unit of currency.
Dad: And the uppercase 'B' ?
Son: Bitcoin with a capital 'B' is typically associated with Bitcoin, the protocol and payment network or to refer to the ecosystem as a whole.
Dad: So, "Saving in bitcoin is investing in Bitcoin."
Son: "Stacking sats makes Bitcoin better."

Dad: Son, how does Taproot make Bitcoin fungible?
Son: Hi Dad,
With Taproot/Schnorr, all on-chain transaction outputs for spending look the same.
Dad: All transaction outputs? Even multisig??
Son: Yes, multisig and opening or closing lightning channel look like any other normal Bitcoin transaction. There are no more "multisig m of n" labels shown in the Block Explorer.
Users can combine signatures into one key and use it as programmable funds, also known as "smart contracts", without identifying the purpose, which improves both privacy and fungibility. The best is, these transactions are smaller and cheaper.

Litecoin is also a fork of Bitcoin with the block time and mining algorithm changed.

Think of it as a record of ownership at a certain point in time.
The "point in time" is measured as "block height", which is the number of blocks in the chain between a given block and the very first block in the blockchain.
Dad: So the blockchain can also be used to measure time?
Son: Yes, exactly, that's why Satoshi also called the blockchain a "timechain".

Dad: Son, what exactly is "difficulty adjustment"?
Son: Hi Dad,
The "difficulty adjustment" is why Bitcoin will never die.
The more people are mining, the harder it gets to find a new block and vice versa. This ensures that, on average, a new block is found every 10 minutes.
Dad: Son, literally no one outside of Bitcoin knows or understands what the "difficulty adjustment" is.
Son: Weightlifters maybe do.

One Bitcoin should already be worth many times more, as rare as Bitcoins are.
Son: Hi Dad,
Yeah, buy as much as possible of the artificially low-cost asset, and move it off the exchange into cold storage.
They may be able to delay the death of the dollar, but Bitcoin's settlement properties make this type of attack impossible to win.
The question is not "if", but "when".
Dad: At the same time, one Bitcoin is already so expensive that it will be impossible for most to own a whole coin.

Dad: Son, what is an "Epoch" in Bitcoin?
Son: Hi Dad,
With a "Bitcoin epoch" people usually mean a period of roughly 4 years (210,000 blocks and about 10 minutes between them) with a specific mining reward.
The first epoch started with the genesis block in 2009, and a block reward of 50 bitcoin.
From May 2020 until some time in 2024, we're in the 4th mining epoch, and the block reward is at 6.25 bitcoin per block.
Dad: I see a bitcoin supply squeeze coming.

The whole time was a period of preparation.
Growth in solitude. Once matured, in two months or so it grows upwards of 90 feet, towering over everything around it.
Okay, not "a few years with nothing valuable", but still Bitcoin is like bamboo.
Dad: That is a great analogy. It is also interesting to mention that bamboo that bends is stronger than the oak that resists.

A "hash" is like a "digital fingerprint" of any collection of data. Each new fingerprint builds on a previous one and adds a chain link segment.

"Cold storage" is a general term for different ways of securing bitcoins offline. Your signing keys are disconnected from the internet.

For storing funds long term, use a dedicated hardware wallet like the "Coldcard" or the "Passport". However, multisig – a "signing combination" of various wallet – would be the best solution.

This is a bad idea that should not be done because if one set of words is discovered, then it becomes far easier to brute force the rest of the seed phrase.
Storing bitcoin in multiple locations like this should be done with multi-signature wallets instead. A 2-of-3 quorum is a great configuration to secure your funds.

It's a "derivation path" and it describes how your Hierarchical Deterministic (HD) wallet derive a specific key within a tree of keys.
For example, if you want to get the next address from a wallet, it just increases the last number by one.
Dad: So this means that all receiving addresses are already known when the wallet is created?
Son: All receiving addresses, all change addresses, all accounts and much more are known from the beginning. Everything is derived from your 12 or 24 seed words using a derivation path.

Son: Dad, one day, my kids will say: "I'm old enough to remember when you could buy bitcoin with fiat currency."
Dad: Son, should it not read "I'm old enough to remember when you could stack sats with fiat currency."?
Son: Yeah. Anyway. I'm still surprised by that.

1. Nobody has enough bitcoin.
2. Nobody understands Bitcoin completely.

Dad: Son, owning a fraction of a Bitcoin is life-changing.
Son: Hi Dad,
I am not sure if your 200 bucks worth of bitcoin will be life-changing one day. ;-) But yes.
Dad: It is life-changing. I am reading more today and question the mainstream media more than ever.
Son: I truly agree, Dad. Many more things will change when you fall deeper down the rabbit hole.
Dad: Son, what changed for you?
Son: Everything – from steak to stacking SATs.

Dad: Son, how can I convert a 24 word seed into a 12 word seed (BIP39)? 12 words can be better memorized.
Son: Hi Dad,
Converting a 24 into a 12 word seed is impossible.
According to BIP 39, a mnemonic seed is converted into a binary seed using PBKDF2-SHA-512.
To turn a 24 word seed into a 12 word seed, you'd need to find a 12 word seed that produced the same binary seed, which is believed to be impossible.
Dad: Oh, I see.
It will take me a while to learn all 24 words.

Dad: Son, what if the Opendime is lost?
Does the Opendime also have recovery words?
Son: Hi Dad,
An Opendime is made to change hands, like cash.
The private key is generated on the device, and without breaking the seal by pushing a pin through the hole marked on the back of the Opendime, there is no way to back it up.
Dad: And if I break the seal?
Son: Then the private key will be revealed in the private-key.txt file and QR code image. There is no way back, and once unsealed, you should move the funds into another wallet.

Dad: Son, so, Bitcoin is open-source? What does this mean exactly?
Son: Hi Dad,
The term open source refers to something anyone can independently review, modify and share because its design is publicly accessible.
Dad: So, everything is public and there are no secrets, except your own?
Son: Your private keys are private, of course.
Everything else is public and auditable. In this beautiful asymmetry lies the true power of Bitcoin.

Dad: Son, it's too early for mainstream adoption.
There are otherwise intelligent people who still think Bitcoin is going to zero.
Son: Hi Dad,
Yes, we are so early.
In the year 2050 “Bitcoin is crashing from $20 million per coin to $19 million per coin!
It’s going to zero! I has no intrinsic value!”
Dad: Son, not sure that I will live to see it.
I would be over 100 years old.

Dad: Son, who else can see my balances on the Bitcoin blockchain?
Son: Hi Dad,
Everybody can see yours and all other unspent transaction outputs (=UTXO) on the chain. The blockchain is a public ledger, and that's the point. The question is, which coins are yours? ;-)
Dad: Is this not a huge privacy issue?
Son: You will be fine if you use Bitcoin correctly.
Dad: Son, please define "used correctly".
Son: Use a new Bitcoin address each time you receive a new payment and consolidate your coins wisely.

Nothing.
Get a signing device and split wallet functionality from transaction signing.

No, not at all! Bitcoin is not only for individuals. Publicly traded companies own bitcoin too.
Dad: Can you name a few?
Son: Visit https://bitcointreasuries.net and find out for yourself.
Dad: Impressive. These companies hold huge amounts!
Son: It's just the beginning. More will follow, imagine what happens then. Oh, and did you notice that countries are on that list as well?

Dad: Son, what stands the term "RBF" for?
Son: Hi Dad,
"RBF" stands for "Replace By Fee". "RBF" allows to replace a stucked or unconfirmed transaction with a new one that uses a higher fee.
Dad: Son, this seems a useful feature to save fees.
Son: Yes.
Please note that the "replacement" transaction uses the same inputs as the original one.

Dad: Son, how many Bitcoins does, or did, Satoshi have? Many, I am certain, since he was early. ;-)
Son: Hi Dad,
Some estimate Satoshi had around 980,000 bitcoins. This number is heavily debated, though.
Dad: Estimate based on what? Why do we know that?
Son: The blocks mined by Satoshi have a special pattern, like a fingerprint.
We do not know who Satoshi was, but we know with high probability the number of bitcoins he had. Satoshis' coins never moved and are considered lost forever.
I'm pretty sure even Satoshi felt short bitcoin. ;-)

Dad: Son, what is the difference between blockchain and Bitcoin? Is there even a difference?
Son: Hi Dad,
"Blockchain" is the technology that underpins Bitcoin, and transactions are stored in blocks.
Think of it as a decentralized database or a decentralized ledger.
"Bitcoin" – the coins or the "value" – are the unspent transaction outputs that are stored on the blockchain.
Dad: Where on the blockchain?
Son: If the blockchain were a material flow or Sankey diagram, you would find the stored value at the ends of the diagram.

Dad: Son, tell me something interesting about "Bitcoin Transactions".
Son: Hi Dad,
Ok. A "Bitcoin Transactions" can consist of many inputs and many outputs. The inputs are outputs of previous transactions which you want to spend, and each output has values assigned to an address.
In general, a transaction is expected to have 2 outputs, the "destination address" and the "change address".
Dad: So, the remainder of the funds are moving on chain as well?
Son: Yes, you always have to move the whole unspent transaction output, also known as "UTXO" or coin.

This is a wonderful and powerful thing.
