Dad: Son, Bitcoin is like water. Son: Hi Dad, Yes, but also... Bitcoin is like a sponge that soaks up value over time, only to release it when needed. Dad: Okay, let's agree on "Bitcoin is." #Bitcoin

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. #Bitcoin

Son: Dad, Become your own bank and stop worrying about banks going bankrupt. Dad: Son, mother and I now have a fraction of our reserve in bitcoin. Son: Great. Every fraction of a bitcoin you own is a safer and more secure store of value compared to the fractional reserve scam used by traditional banks. #Bitcoin

Son: Dad, you can spend a fraction of a bitcoin. Dad: Son, no, thank you. That is out of question. Son: The question is: What is your unit of account. #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

Son: Dad, there is no such thing as overproduction in Bitcoin. Bitcoin always paces itself. Everything works as designed and everything is in perfect order every 10 minutes on average. Dad: Son, it seems to me that Bitcoin runs as accurately and precisely as a Swiss watch. Son: Bitcoin is indeed a great timekeeper. #Bitcoin

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. #Bitcoin

Son: Dad, few people know that our local government's currency is not backed by gold. Dad: Many do not even want to know. #Bitcoin

Dad: Son, what about "paper wallets"? Son: Hi Dad, Don't use them nowadays. These paper wallets are considered unsafe for various reasons. Dad: What should I use instead? Any suggestions? Son: "Opendimes" are today's paper wallets. This is a very safe and effective way to generate a uncompromised private key. Dad: And then I load the private key into BlueWallet? Son: If you want to move your funds, then yes. #Bitcoin

Dad: Son, dollar gains from stocks, bonds and ETFs have distracted me from how powerful Bitcoin is. Then I was distracted about the increasing dollar value of my sats. It took me a while... Son: Hi Dad, This happens to most people. As long as you don't fall into the shitcoin trap, you're already one step ahead of many. #Bitcoin

Son: "My name is ██████ and it's been zero days since I bought some bitcoin." Dad: Son, are you okay? Son: Yeah, I just can't get enough. #Bitcoin

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

Dad: Son, what does m/44'|48'|84'/0'/0' mean? Son: Hi Dad, 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. #Bitcoin

Dad: Son, if you are feeling down, text mum. Son: Dad, yes, I would – and buy some bitcoin. #Bitcoin

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. #Bitcoin

Dad: Son, what is the mempool? Son: Hi Dad, A mempool, also known as "memory pool", is the queue of pending and unconfirmed transactions for a Bitcoin network node. Dad: And who controls the mempool? Son: There is no one global mempool: every node on the network maintains its own mempool, so different nodes may hold different transactions in their mempools. #Bitcoin

Dad: Son, meanwhile, I have more trust in Bitcoin than in my bank. Son: Hi Dad, You are not the only one. With Bitcoin, you no longer need to trust any centralized entity or any counterparty. Bitcoin is a trustless system. Dad: Ironically, the vast majority of people still do not trust mathematics, cryptography and the protocols. Son: Few understand this. #Bitcoin

Dad: Son, I'm still happy I changed my mind on Bitcoin. Son: Hi Dad, Many people will feel the same way. For everyone else, it will simply be "normal" one day. #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
