Saw some people panicking or asking about quantum computing's impact on crypto.
At a high level, all crypto has to do is to upgrade to Quantum-Resistant (Post-Quantum) Algorithms. So, no need to panic. 😂
In practice, there are some execution considerations. It's hard to organize upgrades in a decentralized world. There will likely be many debates on which algorithm(s) to use, resulting in some forks.
And some dead project may not upgrade at all. Might be a good to cleanse out those projects anyway.
New code may introduce other bugs or security issues in the short term.
People who self custody will have to migrate their coins to new wallets.
This brings to the question of Satoshi's bitcoins. If those coins move, then it means he/she is still around, which is interesting to know. If they don't move (in a certain period of time), it might be better to lock (or effectively burn) those addresses so that they don't go to the first hacker who cracks it. There is also the difficulty of identifying all his addresses, and not confuse with some old hodlers. Anyway, it's a different topic for later.
Fundamentally:
It's always easier to encrypt than decrypt.
More computing power is always good.
Crypto will stay, post quantum.
COLDCARD + @covewallet makes self-custody extremely simple.
Quick setup. Clear work flow. No guesswork.
This walkthrough shows how it works.
We're giving away a COLDCARD Q to help some upgrade their self-custody.

My wife bought a 2022 model Y performance about 2 months ago. She flew to Nashville to pick it up as we live in south Alabama. The car was dirty and the interior headliner and sun visors are stained. She called me when she picked it up and said it was making a weird noise. I figured she wasn’t used to an EV sounds. When she made it home I drove it the next day and instantly heard the strange noise. We called the service center and were told it was normal for model Y and may need to be lubricated. We took it in for service and the rear drive unit ended up being replaced and she was without her car for two weeks. The car seems fine now except the headliner and sun visors are still stained. I think the car could have been inspected, driven and detailed before she received it and most of the issues she has incurred would have been avoided. She specifically bought her used model Y from Tesla thinking she would receive the best product with the best service. That didn’t go as planned unfortunately.
