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

Dad: Son, do you have a good Bitcoin investment strategy you would like to share? Son: Hi Dad, Sure. Don't trade, don't sell – that's the strategy. Holding bitcoin is savings, not investing. People with a high time preference will invest their fiat money seeking for fiat gains. #Bitcoin

Dad: Son, I am getting old. I need a backup solution for my passphrase. I think getting another Cryptosteel Capsule. I have so many tiles left. Do you know if I can buy only a Capsule container without the tiles? Son: Hi Dad, Yes, you can buy an empty Capsule. This package includes no tiles or separators and is perfect for backing up a passphrase. On the Cryptosteel website, go to 'Products' > 'All Products' > 'Shop'. Use the coupon "TEACH_ME_BITCOIN_SON_CS10" during checkout to get 10% off! Dad: Great, found it. Thank you. :-) #Bitcoin

Dad: Son, many people I know have cryptophobia. Son: Hi Dad, I'm not surprised. Bitcoin is like early electricity. Raw, dangerous, very volatile and hard to use. With time, Bitcoin will feel much safer, easier to use, and simply normal. Dad: I also believe that Bitcoin is here to stay. Son: Like electricity, it will inspire and power new unimaginable industries. And one day we will wonder how we could live without Bitcoin. #Bitcoin

Son: Dad, Bitcoin scarcity is intensifying as soaring demand triggers an imminent explosion. Dad: Son, so does this mean that a price explosion is imminent? Son: The question is not if, but when. #Bitcoin

Dad: Son, cam yuu hlp be to make a bitcorn paymentt? Son: Dad, what's wrong? Are you drunk?! Dad: Alk goood. coudl be, .. maybe jhst a little too muvh of that finee botttle, .. Son: 4 things not to operate intoxicated: 1. Firearms 2. Heavy machinery 3. Vehicles 4. Bitcoin That's my message for today, Dad. Talk tomorrow. #Bitcoin

Dad: Son, what exactly is "difficulty adjustment"? Son: Hi Dad, The "difficulty adjustment" is why Bitcoin will never die. The more people are mining, the harder it gets to find a new block and vice versa. This ensures that, on average, a new block is found every 10 minutes. Dad: Son, literally no one outside of Bitcoin knows or understands what the "difficulty adjustment" is. Son: Weightlifters maybe do. #Bitcoin

Dad: Son, I feel embarrassed asking this question, but what is the difference between a full node and a miner? How do I get my full node to mine? Son: Hi Dad, A full node verifies blocks. A miner creates blocks. A full node on a Raspberry Pi is not made for mining. You need specialized equipment to mine. Dad: Son, that is a pity. I was hoping to make some sats. #Bitcoin

Son: Dad, FUD (Fear, Uncertainty and Doubt) does not help on your Bitcoin HODL journey. 99.99 percent of the news is irrelevant and makes you feel bad at the end of the day. Yet, you watch it anyway, Dad. Every single day. Dad: Son, you are not going to sell your sats and watch the BTC price anyway. Every single hour, 100 times a day. Son: Touché. #Bitcoin

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. #Bitcoin

Son: Daily reminder: Dad, no one is coming to secure your wallet's recovery seed words for you. ;-) Dad: Son, thank you for helping me to help myself. With a Cryptosteel, it was done in no time. Thank you for the recommendation and the "TEACH_ME_BITCOIN_SON_CS10 " coupon code. Son: You're welcome, Dad. Glad you did it. Have you secured the passphrase too? Dad: Yes, I did. Got a "Capsule Duo". #Bitcoin

Son: Hello there How’s your trading going? Dad: Son? #Bitcoin

Son: Hi Dad, Men lie, women lie, but code and numbers don't. Dad: Son, you are speaking the truth. #Bitcoin

Son: Dad, someone who loves Bitcoin podcasts is a sign of a cool person who hasn't let me down yet. Dad: Son, why that conclusion? Son: First, this person likes to learn and, Second, this person loves Bitcoin. That's why this person must be pretty cool. :-) Dad: However, do you have a podcast recommendation? #Bitcoin

Dad: Son, what are you going to do when Bitcoin wins? Son: Hi Dad, Bitcoin has already won. Many just don't know it yet. #Bitcoin

Dad: Son, what is an "Epoch" in Bitcoin? Son: Hi Dad, With a "Bitcoin epoch" people usually mean a period of roughly 4 years (210,000 blocks and about 10 minutes between them) with a specific mining reward. The first epoch started with the genesis block in 2009, and a block reward of 50 bitcoin. From May 2020 until some time in 2024, we're in the 4th mining epoch, and the block reward is at 6.25 bitcoin per block. Dad: I see a bitcoin supply squeeze coming. Son: Dad, me too. #Bitcoin

Dad: Son, understanding what Bitcoin is, is damn hard. Explaining it to someone else is even harder. Have you tried? Son: Dad, you're absolutely right on that. Aside from the fact that Bitcoin is different things to different people, the term "Bitcoin" is also used equally for different things. Dad: The confusion is immense. Son: "Giacomo Zucco" tweeted no long ago, "Bitcoin's Layer 1 Protocol (BP) is about time. Bitcoin's Layer 2 Protocol (LNP) is about space." I really like the concept of "BP" and "LNP". Dad, what do you think comes on top of "LNP"? #Bitcoin

Son: Dad, Stacking something is better than nothing. Dad: Son, the hardest part is getting started. Son: Since Relai it's relai easy. Download the app and you are ready to go. Don't forget to use code "TEACHIN". Dad: Why? Son: 0.5% lower fees for you, and some supports us. Thank you. #Bitcoin

Dad: Son, is it possible to sell Bitcoins? Son: Hi Dad, Yes, it's possible. Most exchanges that let you buy bitcoins also let you sell bitcoin, for a fee, of course. So, ... Could you sell? Yeah, sure. Should you sell? Hell, no! #Bitcoin

Son: Dad, don't forget to invest in your friendships. Tell your friends about Bitcoin today. Dad: Son, what is the easiest way to get someone to start using Bitcoin? Son: Dad, onboarding friends to Bitcoin is like 1-2-3. 1. Install BlueWallet on friend's mobile phone. 2. Create a wallet and get a receiving address. 3. Scan the QR code and send $10 worth of sats. Dad: So, it costs me $10 to orange pill a friend? Son: Dad, orange pilling is priceless! #Bitcoin
