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.

Son: Dad,

Passphrases are easy to use.

Dad: Son, that is why everybody should use it. Right?

Son: Passphrases are easy to lose.

Dad: Uhm, that is bad. What do you suggest?

Son: That's why everybody should use a Cryptosteel.

Dad: It is not easy to do everything right.

Son: Get a "Capsule Duo". Use one for the recovery seed words and one for the passphrase. Store both Capsules on different locations. That's it.

#Bitcoin

Son: Dad, did you know that Bitcoin transactions are recorded in blocks on a chain called the blockchain?

Dad: Son, I have heard the term "blockchain" before.

How does it prevent double-spending?

Son: Each bitcoin can only exist in one block at a time, so it can't be in two separate blocks simultaneously. What we call "bitcoin" or "coin" refers to an unspent transaction output, alternatively identified as "UTXO".

Dad: Ah, got it. That ensures the integrity of the transactions then.

Son: Exactly, Dad! It's one of the reasons why Bitcoin is considered secure and trustworthy.

#Bitcoin

Dad: Son, what about ETH, XRP and Doge?

The media are very positive about them.

Son: Hi Dad,

These are all shitcoins, and shitcoins are true parasites.

I would not catch one.

#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 do you actually do all day besides your family, your work and Bitcoin?

Son: Hi Dad,

I'm a sats collector, a volunteer UTXO curator and a lifelong learner.

Oh, and did I mention I'm on Twitter a lot? ;)

#Bitcoin

Son: Dad,

Measuring your wealth in fiat is _____ .

Measure it in bitcoin and time instead.

Dad: Yes – an exiting time.

#Bitcoin

Dad: Son, what is the biggest risk in Bitcoin?

Son: Hi Dad,

The biggest risk is having no bitcoin at all.

#Bitcoin

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.

#Bitcoin

Dad: Son, this Bitcoin thing is overwhelming.

Can you present me a five-point plan of measures? I appreciate your help.

Son: Hi Dad,

Self sovereignty is tricky.

However, It's not black or white – it's a gradient.

Start and try to improve your setup over time.

Test it, find security holes, privacy leaks and fix them. Iterate over and over again.

#Bitcoin

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.

#Bitcoin

Dad: Son, there are less expensive bourbons.

Son: Hi Dad,

There are also thinner steaks and smaller cars.

Many ways to stack more sats.

#Bitcoin

Dad: Son, what about the latest Bitcoin change requests?

Son: Hi Dad,

Bitcoin is like a tree, and your wealth is like its shadow; when the tree is gone, the shadow disappears.

We should really take care of Bitcoin and avoid risks at all cost.

Dad: Send more sunshine!

#Bitcoin

Dad: Son, is it "cool storage" or "cold storage"?

Son: Hi Dad,

It's "cold storage".

The term does not matter, as long it's "your storage" and "your storage" is offline.

#Bitcoin

Dad: Son, everybody has heard about Bitcoin.

Many want it, especially when the price goes up.

Few people are actually holding Bitcoin. Why?

Son: Hi Dad,

The difference between the two is action.

First you have to learn, then buy or earn.

You have to make an effort.

Dad: No pain, no gain.

Son: Nah, more like "Work hard, have fun and make a difference." The life is bright in Bitcoinland. :-)

#Bitcoin

Dad: Son, what makes Bitcoin so powerful?

Son: Anyone, anywhere, can start using bitcoin right now. No permission is required.

Let that sink in, Dad.

#Bitcoin

Son: Dad, did you know that Bitcoin will take care of you, if you take care of your bitcoin?

Dad: Son, no, I did not know that.

Son: It's true, Dad. You should take care of your bitcoin.

Dad: What is the easiest way to do this?

Son: Start simple and improve on the go.

- Go off exchange and use a hardware wallet

- Secure your seed words in a Cryptosteel Capsule

- Test your setup and backups regularly

#Bitcoin

Son: Dad, is your stack bigger today than last week?

Dad: Yes, son.

Son: Did you get your coins off exchange?

#Bitcoin

Son: Good morning, Dad.

Bitcoin is in top form today,

as yesterday,

and the day before.

I hope you are as well.

Dad: Son, good morning!

There is nothing to complain about. :-)
