This video is from an old Coldcard tutorial showcasing dice rolls to add entropy. If you have no other hardware to migrate to but are worried about being on a hot wallet until you find a replacement device, this is just one of many possible options for the time...

DON'T LET YOUR BITCOIN DIE WITH YOU 💀 ⚰️ Yea look, nobody likes to admit it but we all have to die one day. As I've been talking to people about their self custody lately - both Casa members and not - I hear the same thing over and over. "What happens if I die?" Many people feel pretty good about their bitcoin security for themselves. But their family members often have no idea how to use this stuff. Hardware wallet? Seed phrase stamped on metal? Shamir's secret sharing backups using SD cards, a passphrase, and a treasure hunt through the backyard with a shovel? 😵 We're solving that problem for all Casa members, starting today with Casa Inheritance. A key design principle we kept while building this was to make it as simple as possible for Recipients (your family members that will receive your bitcoin if you pass), while maintaining Casa-level security. An estate transfer is already a stressful time for family, and it can become even more stressful if you add in a crazy treasure hunt to access a fortune in bitcoin. For our basic 3 key vaults, we wanted it to be as easy as using the app. No metal plates, no need to use a hardware wallet, no magic passwords you have to keep track of or else risk messing up the asset transfer. Simplicity is security. So how does it work, in detail? A Vault Owner (Casa member) designates a Recipient (their family or friend) in the Casa app. The Recipient receives an invite to create a free Casa account. The Recipient scans a QR code provided by the Vault Owner, which contains an encrypted version of the owner's mobile key. This encrypted key is only able to be imported by the Recipient's Casa account, and the Recipient can't initially use it or see the vault balance. If the Vault Owner passes away, the Recipient can request access to the vault in their Casa app. This starts a 6 month timer, and sends a ton of notifications every month to the owner. If the owner is still alive, they can reject the request in app. If they are not, the timer will run out. When it does, the Recipient will be able to use the shared mobile key and the request a signature from the Casa Recovery Key for the shared vault. This gives them 2 out of 3 signatures, enough to access the assets. For 5 key vault users, one hardware key is shared with the Recipient. This small increase in friction for Recipients is often worth it for the increased security and resilience of a 5 key vault for larger holdings. To summarize now that you have the details: 1. Share keys and vault access during setup 2. 6 month timelock to ensure no malicious theft 3. Use shared keys and Casa key to access assets Full setup takes less than 5 minutes. Inheritance is one of the biggest problems in self custody today. If you've hodled through years of painful bear markets, you owe it to yourself and your family to not let the reward for that patience go to zero because you didn't have a plan - and we're here to make that easy. Check out the video to see how easy it really is. Like I said earlier this week - Casa is going after major problems in self-custody this year. Check this one off the list ✅. Next one coming sooner than you think 🔥.

Peter Thiel on $NVDA (about a year ago): It is probably quite tricky. If you had to concretize it, one thing that is very strange is if you just follow the money, at this point 80 to 85% of the money in AI is being made by one company, it is NVIDIA. It is all on this very weird hardware layer, which Silicon Valley does not even know very much about anymore. We do not really do hardware, we do not do silicon chips in Silicon Valley anymore. I get pitched on these companies once every three or four years, and it is always, I have no clue how to do this, it sounds like a pretty good idea, but man, I have no clue, and we never invest. There is this theory that the hardware piece makes the money initially, then gets more commodified over time, and it will shift to software. And the, I do not know, multi trillion dollar question is whether that is going to be true again this time, or whether NVIDIA will have this incredible monopoly. I suspect NVIDIA will. I think it will maintain its position for a while. I think the game theory on it is something like this. All the big tech companies are going to start trying to design their own AI chips so they do not have to pay the 10x markup to NVIDIA. How hard is it for them to do it? How long will it take? If they all do it, then the chips become a commodity and nobody makes money in chips. So do you go into hardware? You should do it if nobody else is doing it. If everybody does it, you should not do it. I am not sure how that nets out, but probably people stay stuck for a while and NVIDIA goes from strength to strength for a while.
