Son: Dad, did you know? Bitcoin Core is one of the most reviewed software, maybe it's the most reviewed software ever. Dad: Son, why is that? Son: Bitcoin Core has the biggest bug bounty ever. #Bitcoin

Dad: Son, what is a "Bitcoin block" exactly? Son: Hi Dad, Think of it as a record of ownership at a certain point in time. The "point in time" is measured as "block height", which is the number of blocks in the chain between a given block and the very first block in the blockchain. Dad: So the blockchain can also be used to measure time? Son: Yes, exactly, that's why Satoshi also called the blockchain a "timechain". #Bitcoin

Dad: Son, how long does it take to pay using Lightning? Son: Hi Dad, A LN payment takes only a fraction of a second. Dad: Wrong! Although payments take only a couple of seconds, you usually need at least two minutes to discuss with the counterparty how fucking awesome the Lightning Network is. Budget your time accordingly, son! Son: LOL. Thanks for your advice, Dad. :-D #Bitcoin

Dad: Son, what if the Opendime is lost? Does the Opendime also have recovery words? Son: Hi Dad, An Opendime is made to change hands, like cash. The private key is generated on the device, and without breaking the seal by pushing a pin through the hole marked on the back of the Opendime, there is no way to back it up. Dad: And if I break the seal? Son: Then the private key will be revealed in the private-key.txt file and QR code image. There is no way back, and once unsealed, you should move the funds into another wallet. #Bitcoin

Son: Dad, I'm grateful that you taught me this: "Good habits and simple rules, if applied, can positively change your whole life." Dad: Son, how did you put that to use? Son: Numerous ways, but one of them is stacking sats, no matter what happens. Dad: Son, that seems to have paid off. #Bitcoin

Dad: Son, who else can see my balances on the Bitcoin blockchain? Son: Hi Dad, Everybody can see yours and all other unspent transaction outputs (=UTXO) on the chain. The blockchain is a public ledger, and that's the point. The question is, which coins are yours? ;-) Dad: Is this not a huge privacy issue? Son: You will be fine if you use Bitcoin correctly. Dad: Son, please define "used correctly". Son: Use a new Bitcoin address each time you receive a new payment and consolidate your coins wisely. #Bitcoin

Dad: Son, what excites you so much about Bitcoin? Son: Hi Dad, We were born too late to explore the oceans, too early to explore the stars, but just the right time to fix the money!! Dad: Great time to be alive! Son: Dad, tell them to buy the ticket and to take the ride … to buy bitcoin. It's not too late, but the time frame in which one can buy bitcoin is slowly closing. #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, is Bitcoin real money? Son: Hi Dad, This depends on how you define the term "money"? Dad: Honestly, I have no idea. Until recently, I was unaware that there is a difference between "currency" and "money". Son: Dad, unfortunately, few people know that. Money is a "Store of Value", a "Medium of Exchange", a "Unit of Account" and a "System of Control". Therefore, bitcoin is the best form of money that we have ever known. However, we are still working on the "Unit of Account" thing. #Bitcoin

Dad: Son, on a scale from 1 to 100,000,000 how satisfied is a bitcoin? Son: Hilarious, Dad. #Bitcoin
