Everybody should have their Bitcoin in Self Custody.
Otherwise you are owing paper.

What if one day the multisig companies (currently rubbing their hands after the Cold Card disaster) are forced by governments to require KYC before they will cosign your multisig transaction, because you lost one of your keys?
Pay attention.

Governos e empresas, sempre unidos contra a privacidade. KYC é a senha secreta para controlar sua liberdade financeira. Quem precisa de hackers quando tem burocracia?

simple, to verify it is to expose it 🤷🏻‍♂️

You don't need to buy an hardware wallet. The podcasters and HW companies are scamming you.
You can use an old laptop and make it air gapped by removing WiFi card, Bluetooth, and disable the Ethernet port. Do encrypt the hard drive. Never connect it to the internet.
Use it as your hardware wallet, generate your own seed with dice, and use sparrow to sign PSBT.
For additional double checks, get a seedsigner.
This hardware wallet business companies must end.
Study, you can do it!

"The people affected by this did everything right. They generated their seed on an air-gapped device using a random number generator..."
No @Simply Bitcoin, they did not do everything right.
They made the two mistakes every Bitcoiner should avoid:
- Trusting the device to generate the seed on their behalf.
- Failing to verify whether the generated seed was actually secure (I'm sure most of you guys have heard of Ian Coleman's tools).

In other words, they replaced Bitcoin's core principle of "Don't trust, verify" with "Do trust, don't verify."
I'm sorry, but that is not "doing everything right."
If they had generated their seed themselves using dice and protected it with a strong passphrase, they would have had time to move their funds.

Yes, Coin Kite has some responsibility. But the real problem is that most people lack the foundational knowledge to understand why they shouldn't delegate seed generation in the first place. When things go wrong, it's easier to blame the company than to admit you trusted them with something you should have controlled yourself.

The first thing you learn in IT is that computers cannot generate truly random numbers, only pseudo random ones.

I saw Cold Card users tweeting "what is a passphrase?", which reveals widespread ignorance.

The real disaster is the educators. Bitcoin has abundance of podcasters and influencers, yet almost none discuss entropy or how to generate your own seed phrase properly. It's far more lucrative to promote every hardware wallet on the market like they're consumer products than to do the hard work of teaching security fundamentals.
