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. #Bitcoin

Dad: Son, why not load the seed words into another wallet and spend all the Bitcoins twice? Son: Hi Dad, That's not how it works. Bitcoins cannot be double spent. Bill Gates once said: “Bitcoin is a technological tour de force.” Think about it... Bitcoins are purely digital and at the same time something that cannot be copied. Dad: That is indeed very impressive, son. #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, don't ask a cab driver about Uber or a central banker about Bitcoin. Son: Hi Dad. Stop. Telegraph decoded. Stop. You too, have a fantastic day! Stop. #Bitcoin

Son: Dad, Bitcoin is the best money humans ever had. Bitcoin is secure, decentralized, permissionless, borderless, and settles within an hour, regardless of the value sent. Dad: Son, these are all indeed fascinating properties, and "One world, one money!" Son: Exactly, Dad. Bitcoin is the future. Embrace it, one block at a time! #Bitcoin

Dad: Son, bitcoin is worthless. Son: Hi Dad, Have you ever paid taxes on your bitcoin? #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, 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, what do you recommend to your friends? Son: Hi Dad, "Pay attention to Bitcoin and educate yourself." or "Invest in yourself, invest in Bitcoin." Dad: Son, why exactly this recommendation? Son: Because Bitcoin is the hardest money, the greatest monetary and technological revolution since the Internet itself. It's not a fad. Dad: I also believe that Bitcoin will not go away. Son: Bitcoin is here to stay — that's for sure – and it will transform money, the Internet and so much of the world around us. It's just starting... #Bitcoin

Son: Dad, there's no friend as loyal as a bitcoin. Dad: Son, "as a book". Ernest Hemingway said, "There is no friend as loyal as a book." #Bitcoin

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. ;-) #Bitcoin

Son: Dad, volatility is _______________. Dad: Son, that must be "nerve-wracking". Volatility is nerve-wracking. Son: For me, volatility is "the price for being early". #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. :-) #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

Dad: Son, I just bought a bitcoin. Son: Ahh.. the beginning of a deep friendship! #Bitcoin

Dad: Son, what is a passphrase? 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. Dad: Okay, that is a powerful feature! Son: So little effort and so much more security. #Bitcoin

Dad: Son, what is "Coin Control" and what is it for? Son: Hi Dad, In Bitcoin, not every UTXO is the same, even if the amount is exactly the same. Dad: An "UTXO" is a coin or note in my wallet, right? Son: Yes. With coin control, you can choose which coin or note you want to spend. It like choosing a note by its serial number. Coin control is crucial for maintaining privacy. Make sure to use it. #Bitcoin

Son: Thanks __________________ for Bitcoin. Dad: Son, who is going to fill the blanks? #Bitcoin

Dad: Son, what is the best application for lightning? Son: Hi Dad, Bitcoin payments and killing shitcoins. #Bitcoin

Dad: Son, how much have you lost trying to trade? Be honest. Son: Hi Dad, I leverage traded once, and again. I got liquidated and many sats changed hands. For me, trading is gambling. Never again. After many blocks, I still can feel the pain. Dad: Everybody wants more sats, as it seems. Son: That's true, Dad. Lessons learned. #Bitcoin
