Son: Hi Dad,
We need to separate money and state.
We need to separate economy and state.
Dad: Son, I cannot agree more. Just like the separation of church and state, it is time we separate money and state, and economy and state as well.
Son: Let's empower individuals and ensure true economic freedom.
Dad: Thank you, Satoshi, for Bitcoin.

Dad: Son, what about trading bots?
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.

"The more you learn,

the more you stack,
the more luck you will have."
Dad: Son, "The amount of good luck coming your way depends on your willingness to act."
That is a quote from "Barbara Sher" which basically says the same thing.
Son: .., but without Bitcoin – a huge difference.

Dad: Son, how do you generate these 24 seed words?
Do you pick random words from your head?
Son: Hi Dad,
This doesn't work that way. First, these words are special words, taken from the "BIP39 Word List". Second, picking words from your head is not random and therefore a bad idea.
I don't always generate a new seed, but when I do, I use dices.
Dad: Why dices? How does this even work?
Son: Dice rolls provide entropy. You could also flip a coin as a source for randomness. The process is simple and is available in BlueWallet (advanced mode), SeedSigner and in every Coldcard.

Dad: Son, guess which ones are mine. ;-)
Jokes aside.
How likely is it that someone could guess one?
Son: In short, extremely unlikely.
Dad: Extremely unlikely? So, it is possible?!

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, what is "Cold Storage" exactly?
Son: Hi Dad,
"Cold storage" is a general term for different ways of securing bitcoins offline. Your signing keys are disconnected from the internet.
Dad: So "BlueWallet" must be a hot wallet?
Son: Yes. It's connected to the internet. This is perfectly fine for daily transactions and smaller amounts.
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.

https://www.teach-me-bitcoin-son.com/media//generated/what-are-hd-bitcoin-wallets.png
Dad: Son, what are "HD Bitcoin Wallets"?
Son: Dad, by definition, wallets are private key and public key management systems. In the beginning, every key pair used had to be backed up individually. That's why many have reused addresses, which is bad for privacy, as you know.
BIP-32 made Bitcoin better and introduced "HD wallets", which stands for "Hierarchical Deterministic", and not for "High Definition". With this BIP, it's possible to generate multiple addresses (public/private key pairs) derived from a single source of random data (=entropy).
Dad: Why was this introduced in the first place?
Son: It makes backing up the random bits of data much easier and safer, especially if combined with BIP-39, which introduced the mnemonic seed words, which is just entropy in a human-readable form.

Dad: Son, I have many small transactions in my wallet. How can I reorganize these for more efficiency?
Son: Hi Dad,
I agree that having an optimized UTXO set is a good idea, but you shouldn't link the transaction history by sending all your funds to a new address.
You could mix your coins using a mixing service, or just combine the UTXOs from the same source.
Dad: How should I know which UTXO can be mixed?
Son: Privacy starts with proper coin control.
From now on, label each UTXO with the payment reason and the sender's name. This helps for further processing.

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: LOL, no Dad, I used a little Python script for that.
Interestingly, the longer the seed (12, 15, 18 vs. 24 words), the fewer valid combinations there are. Of course, these seeds are for fun and testing ONLY!

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, why do you not use numbers based the word’s indexed number in the BIP39 list instead of the first 4 letters of the recovery word?
Son: Hi Dad,
That's a good question. Let's quote the BIP39 creators to answer it.
"A mnemonic code or sentence is superior for human interaction compared to the handling of raw binary or hexadecimal representations of a wallet seed. The sentence could be written on paper or spoken over the telephone"
I think it is wrong to use numbers when the creators intentionally designed the standard so that we use words.
Dad: Ok, makes sense. Thanks.

Son: Dad, your Bitcoin mnemonic seed is as unique as you are.
Dad: Son, while there is a vast amount of genetic diversity, humans share a common genetic framework.
The total number of unique genetic codes is astronomical due to the complex combinations possible with the four DNA bases.
Also, genetic information is inherited and passed down through generations – as you know ;)
Son: A Bitcoin mnemonic seed is a unique word sequence generated from random numbers, mapped to a predefined set of words. BIP-85 allows you to derive a child seed from a parent seed.
Dad: Never thought about it that way!

Son: Hi Dad,
The BIP39 standard supports an optional 25th word, a so-called passphrase. The passphrase encrypts the seed and creates a new wallet.
Dad: Son, do I have limitations? Size, or something?
Son: On the Coldcard hardware wallet for example, passphrases are limited to 100 characters in length. The on-screen interface supports ASCII characters only.

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.

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.

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.

Son: Hi Dad,
Hyperinflation makes all sorts of goods and services essentially unaffordable for the majority of people, but I'm not speaking about bitcoin. ;) Hyperinflation will lead to Hyperbitcoinization. This is why:
Because bitcoin is the hardest money in the world, people will upgrade their "store of value" and just use bitcoin.For me, Hyperbitcoinization is here when prices are expressed in bitcoin, uhm, when prices are expressed in sats.

Money is a "Store of Value", a "Medium of Exchange", a "Unit of Account" and a "System of Control". Therefore, bitcoin is the best form of money that we have ever known. However, we are still working on the "Unit of Account" thing.
