Dad: Son, since most of us cannot afford Bitcoin – is "Bitcoin Cash" still a good deal? Son: Hi Dad, "Bitcoin Cash" is trash. This is not bitcoin. You can buy one dollar worth of bitcoin. #Bitcoin

Dad: Son, how many Bitcoins does, or did, Satoshi have? Many, I am certain, since he was early. ;-) Son: Hi Dad, Some estimate Satoshi had around 980,000 bitcoins. This number is heavily debated, though. Dad: Estimate based on what? Why do we know that? Son: The blocks mined by Satoshi have a special pattern, like a fingerprint. We do not know who Satoshi was, but we know with high probability the number of bitcoins he had. Satoshis' coins never moved and are considered lost forever. I'm pretty sure even Satoshi felt short bitcoin. ;-) #Bitcoin

Son: Dad, I taught my kids that: "The more you learn, the more you earn, the more you stack, the more luck you will have." Dad: Son, "The amount of good luck coming your way depends on your willingness to act." That is a quote from "Barbara Sher" which basically says the same thing. Son: .., but without Bitcoin – a huge difference. #Bitcoin

Dad: Son, is the Bitcoin price artificially suppressed? One Bitcoin should already be worth many times more, as rare as Bitcoins are. Son: Hi Dad, Yeah, buy as much as possible of the artificially low-cost asset, and move it off the exchange into cold storage. They may be able to delay the death of the dollar, but Bitcoin's settlement properties make this type of attack impossible to win. The question is not "if", but "when". Dad: At the same time, one Bitcoin is already so expensive that it will be impossible for most to own a whole coin. #Bitcoin

Dad: Son, this Bitcoin thing is just a passing fad. Back in my day, we trusted banks and cash! Cash was king. Son: Hi Boomer Dad, Times are changing. Bitcoin offers decentralized, permissionless and secure transactions that are final. It's the future! Dad: I don't understand it, and I don't trust it. Son: Don't be afraid, Dad. You might be surprised by the benefits it brings. #Bitcoin

Dad: Son, do you have any idea where I can hide my Bitcoin seed recovery phrase? Son: Hi Dad, No, but I can tell you many bad hiding places that are used by many and therefore known to burglars. Under the mattress, master bedroom, bedroom closet, drawers, safes, cabinets, refrigerator/freezer, toilet tank, vases, and suitcases. These places should be avoided. Dad: What's wrong with suitcases? Son: Surprisingly, people use a suitcase as a not-so-secure safe. Burglars know this. #Bitcoin

Dad: Son, why not use gold as store-of-value? Son: Hi Dad, Bitcoin is the decentralized financial network. It allows individuals worldwide to store and send value to one another without intermediary agents like banks or payment processors. Dad: Okay, well, that sounds promising. Son: It's a technology that will transform the world. Gold can't compete with Bitcoin. #Bitcoin

Dad: Son, how do you generate these 24 seed words? Do you pick random words from your head? Son: Hi Dad, This doesn't work that way. First, these words are special words, taken from the "BIP39 Word List". Second, picking words from your head is not random and therefore a bad idea. I don't always generate a new seed, but when I do, I use dices. Dad: Why dices? How does this even work? Son: Dice rolls provide entropy. You could also flip a coin as a source for randomness. The process is simple and is available in BlueWallet (advanced mode), SeedSigner and in every Coldcard. #Bitcoin

Dad: Son, I am reading the "Bitcoin white paper" right now and try getting my head around this: "The network timestamps transactions by hashing them into an ongoing chain of hash-based proof-of-work, forming a record that cannot be changed without redoing the proof-of-work." Son: Hi Dad, A "hash" is like a "digital fingerprint" of any collection of data. Each new fingerprint builds on a previous one and adds a chain link segment. Dad: Bitcoin seems to be a very sophisticated system. Son: Dad, that's just the tip of the iceberg. #Bitcoin

Dad: Son, having kids does not make you a father. Raising them does. Son: Dad, buying bitcoin doesn't make you a Bitcoiner. Holding your keys does. #Bitcoin

Dad: Son, at this rate I am going, my student loans should be paid off in 3 years. Son: Hi Dad, That's great. Dad: Lessons learned. #Bitcoin

Son: Dad, did you know that from 2100 to 2140, only two bitcoin will be mined! Think about it!! 40 years = two coins! Dad: Son, these coins will be exorbitantly expensive. Son: Exorbitantly expensive, yes, but measured against what?! Real Estate? Gold? Dollars? #Bitcoin

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, 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

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

Son: Dad, I just bought bitcoin. AMA. #Bitcoin

Dad: Son, I have seen into the future. The value of governmental paper bills will continue to go down from here. Son: Hi Dad, I have also seen into the future. I see Bitcoin. Bitcoin is the brighter future. #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

Dad: Son, it's too early for mainstream adoption. There are otherwise intelligent people who still think Bitcoin is going to zero. Son: Hi Dad, Yes, we are so early. In the year 2050 “Bitcoin is crashing from $20 million per coin to $19 million per coin! It’s going to zero! I has no intrinsic value!” Dad: Son, not sure that I will live to see it. I would be over 100 years old. #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
