Dad: Son, I just got my Coldcard hardware wallet today.
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.

We share daily father-son dialogues explaining Bitcoin on Twitter and here on nostr. On Mondays, we send out a recap newsletter with the coolest things Dad has learned during the past week. If you are new to Bitcoin, this will help you get started. If you are already on your journey, this will help you stay up to date, keep away from scams, and avoid the common pitfalls. Our DM is open for your Bitcoin related questions.

Son: Dad, I should have paid more attention to Bitcoin in the beginning and I should have bought more.
Dad: Son, don't blame your past.
Be grateful for what it taught you.
I could say the same...
Now I am just glad I changed my mind on Bitcoin and saved my savings.
#Bitcoin
Dad: Son, is Bitcoin real money?
Son: Hi Dad,
This depends on how you define the term "money"?
Dad: Honestly, I have no idea.
Until recently, I was unaware that there is a difference between "currency" and "money".
Son: Dad, unfortunately, few people know that.
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.
#Bitcoin
Dad: Son, is bitcoin for individuals only?
Son: Hi Dad,
No, not at all! Bitcoin is not only for individuals. Publicly traded companies own bitcoin too.
Dad: Can you name a few?
Son: Visit 
BitcoinTreasuries.NET
BitcoinTreasuries.NET - Top Bitcoin Treasury Companies
Track Bitcoin holdings of public companies, governments, and institutions. Live data on corporate BTC treasuries with real-time valuations.
Son: Dad, buy bitcoin before you need it.
Dad: Son, in my opinion, it is always better to "want" something than to "need" something.
Son: And when you "want bitcoin", you realize that Bitcoin is on every level of Maslow's pyramid.
#Bitcoin
Dad: Son, since most of us cannot afford Bitcoin – is "Bitcoin Cash" still a good deal?
Son: Hi Dad,
"Bitcoin Cash" is trash. This is not bitcoin.
You can buy one dollar worth of bitcoin.
#Bitcoin
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. ;-)
#Bitcoin
Dad: Son, I have seen into the future.
The value of governmental paper bills will continue to go down from here.
Son: Hi Dad,
I have also seen into the future.
I see Bitcoin.
Bitcoin is the brighter future.
#Bitcoin
Son: Dad, what advice would you have given me back then if you had already known?
Dad: Son, this would be "Pay Yourself First".
Son: Yeah, that's a good one, Dad. That is valuable advice that will pay off over time.
Dad: .. or not, if this advice is not put into practice.
Son: Buy bitcoin first after payday, then dollar cost averaging until the end of the month – or end of cash – whatever comes first.
Dad: LOL. Yes, exactly. Something like that, and let me add "always live below your means".
#Bitcoin
Dad: Son, having kids does not make you a father.
Raising them does.
Son: Dad, buying bitcoin doesn't make you a Bitcoiner.
Holding your keys does.
#Bitcoin
Son: Dad, we just got the new car. :-)
Dad: Son, I am glad for you and I wish you many safe trips with it. However, you should have some spare diesel, blankets, food and water in that car. Always.
Son: Yeah, always have backups and a plan B.
#Bitcoin
Son: Hi Dad,
"Not stacked sats are not realized wishes."
People don't quite understand how immoral that is if they already heard of Bitcoin.
Dad: Son, something like the lack of self-care?
Son: Yes, you can look at it that way too.
Or in other words: If you don't stack these Satoshis, you're stealing from your future.
#Bitcoin
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.
#Bitcoin
Son: Hi Dad!
Fun fact: Your bitcoin can't be in two different blocks at once.
Dad: Son, how does it ensure that?
Son: Once a Bitcoin transaction is in a block, it can't be duplicated elsewhere, preventing double-spending. The full previously unspent "coin" moves forward with every transaction.
Dad: I see. So, no room for confusion or fraud?
Son: That's right, Dad!
Bitcoin is designed to be reliable and secure, making transactions trustworthy and final.
#Bitcoin
Dad: Son, who is the CEO of Bitcoin?
Son: Hi Dad,
There is no "CEO of Bitcoin".
Bitcoin is an open, collaborative project that no company or government controls, belonging to the people.
Dad: Son, but someone must have launched it.
Son: Satoshi Nakamoto is the presumed pseudonymous person or group who developed bitcoin, authored the bitcoin white paper and launched the network.
#Bitcoin
Son: Dad, Bitcoin is like Bamboo.
Dad: Son, what? Why should Bitcoin be like bamboo?
Son: Bamboo grows underground, unseen, for a few years with nothing valuable to offer the world.
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.
#Bitcoin
Dad: Son, why is relaying unconfirmed transactions from one Bitcoin node to others necessary?
Son: Hi Dad,
Nodes relay unconfirmed transactions they hear about to one another, and every node has its own, more or less synchronized, mempool.
If there was no mempool, there would be no way for miners to learn about unconfirmed transactions to include in blocks to begin with.
Dad: Why not send directly to the miners?
Son: It's important to think about each party's incentives and needs. Relaying transactions is not a waste, even if a node is not mining. Learning about unconfirmed transactions has value, for example while waiting for a payment.
#Bitcoin
Son: Dad, don't trust everything you see.
Even salt looks like sugar.
Dad: Son, what do you want to tell me?
Son: Use your Umbrel node to verify if your bitcoin is real bitcoin – or you will be salty in the end.
#Bitcoin
Dad: Son, I want one of those 21M Bitcoin so bad!!!
Son: Hi Dad,
I can understand this desire! One thing you should know: There will never be 21M BTC.
Dad: Why not 21M Bitcoin? Was I lied to?
Son: No, no one was lied to. Here is why: The block 501726 was generated without reward (-12.5 BTC), and block 526591 with half a reward (-6.25 BTC)
Also, the 50 BTC in the Genesis Block can't be spent, even if Satoshi comes back.
On top of that, ~4 million BTC have been lost. Well, those coins existed, but were lost. Maybe one or the other Satoshi will find its way back into circulation. However, keep stacking sats.
#Bitcoin
Dad: Son, there are valuable life lessons to be learned from Monopoly. Do you know them?
Son: Hi! Which one do you mean, Dad?
Dad: Just the most important:
Don't sit on too much cash.
Choose your investments and stick with it.
The Bank never “goes broke”. If the Bank runs out of money, the Banker issues as much as is needed.
Finally, avoid jail at all cost.
Son: Most of this can be reached by buying Bitcoin.
