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. #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, 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

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, 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

Son: Hi Dad, We need to separate money and state. We need to separate economy and state. Dad: Son, I cannot agree more. Just like the separation of church and state, it is time we separate money and state, and economy and state as well. Son: Let's empower individuals and ensure true economic freedom. Dad: Thank you, Satoshi, for Bitcoin. #Bitcoin

Son: Dad, I just bought bitcoin. AMA. #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, why do your siblings still have no Bitcoin position? Son: Hi Dad, Good question.... I talked to them again and again and again about it, last time at the latest all-time high. I will do it again, at the next all-time high, every all-time high until they get some sats. Dad: Let us hope that the next all-time high will not be long in coming. #Bitcoin

Son: Dad, to secure your bitcoin, self custody is crucial and delaying it can be more costly than taking action now. Dad: Son, well, I know self custody is important, but I just don't have the time to figure it out right now. Son: Dad, delaying it can be more costly than taking action now. Just do it. I can help you out. #Bitcoin

Dad: Son, do you think bitcoin will eventually become a global currency? Son: Hi Dad, Bitcoin is already a global currency. :-) If you're asking if bitcoin will be the reserve currency, then yes, I think that is very likely. The question is not if, but when. #Bitcoin

Son: Dad, the best weapon you have is always away from view. Dad: Son, yes, it is between your ears, hidden in your cranial cavity. Son: Well, I was thinking of bitcoin, but okay. #Bitcoin

Dad: Son, how can you make a month's salary last forever? Son: Hi Dad, That's a damn good question! I have no idea. Tell me! Dad: It is quite simple. Turn it into bitcoin. #Bitcoin

Son: Yes – Yes – Yes – and so on. Dad: Son? Son: Dad? Dad: What are those "Yes" responses for? Son: That's what my Bitcoin node says when verifying transactions and rebroadcasting the valid ones across the network. #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 is smart money buying right now? Son: Hi Dad, Smart money is buying hard money. #Bitcoin

Dad: Son, what is the difference between a Bitcoin address and a Bitcoin public key? Son: Hi Dad, That's a good question! An address represents a hash of a public key of an asymmetric key pair. The owner of the key pair can use the private key to sign transactions or messages. Dad: Why sign a message? Son: For example, to prove ownership of an address. Only by using the correct private key a valid signature may be created, which then anyone can verify as valid by using the associated address which, again, represents the public key. #Bitcoin

Dad: Son, what is a "block explorer"? Son: Hi Dad, A block explorer is a website, a tool, that is used to view bitcoin transaction details, unspent transaction outputs (UTXO) and addresses online. Dad: So, is it something like a blockchain browser?? Son: Yeah, a blockchain explorer can be used to follow transactions in the graph until they end in an unspent output, an UTXO. These UTXOs are the actual bitcoin, the "data which have value". Dad: Let's play a game. Who will find the address with the most bitcoins – you or me? #Bitcoin
