Yeah, a hardware wallet is good, although for a billion dollars, 100 hardware wallets would be better. Could even go so far as to split a private key into seven horcruxes using Shamir's Secret Sharing and bury them in locations around the world.

Memorizing a seed phrase leaves you vulnerable to a $5 wrench attack, I wouldn't recommend it.

Of course the problem is the attacker may not know what method you used and resort to the $5 wrench attack anyway :)

Not stealing $3.6B might be an even safer bet.

The famous Bitcoin family reportedly spread their hardware wallets across the globe.

The article suggests each location contains 100% of the key, not using Shamir’s Secret Sharing.

> Taihuttu is trying to put a crypto cold wallet on every continent so it’s easier to access his holdings.

I hope it’s at least encrypted with an additional passphrase, otherwise it’s only as strong as the weakest bank’s security.

>>hnburn+66
Wow.

> Taihuttu has two hiding spots in Europe, another two in Asia, one in South America, and a sixth in Australia.

> We aren’t talking buried treasure – none of the sites are below ground or on a remote island – but the family told CNBC the crypto stashes are hidden in different ways and in a variety of locations, ranging from rental apartments and friends’ homes to self-storage sites.

I hope this is all a decoy or else it’s the worst opsec I’ve seen since about five hours ago.

Or the Winklevoss twins who store their codes in separate banks across the country.

I would not want to be a friend to the sort of idiots who would say stuff like this. Having a target painted on my back as a decoy somehow makes it even worse.

>>pshc+(OP)
Reminds me of the man who was sent to jail for refusing to reveal his keys. think this happens alot.

You don’t need splitting the private key. Bitcoin has multisig setup. For example, you can setup your wallet such that 6 out of 10 private keys need to sign in order to transfer funds. Spread that 10 private keys out. Or 3 out of 10. Or 2 out of 5. Any n out of m.

>>nether+cN
You're right, gathering multisigs would be much safer than gathering SSS shares because you wouldn't be carrying around bits of the private key.

>>pshc+(OP)
For the attacker, the problem isn't about protecting the crypto but to launder.

If gov got to you, it probably doesn't matter how well you got it protected.

>>pshc+YQ
Any single SSS share does not disclose any additional information about the private key (i.e. it is not like splitting the key itself into parts).

>>sratne+Q51
And SSS also allows n out of m.

still: physical threat + seed phrase cracked > physical threat

>>pshc+(OP)
You're still memorizing the seven locations around the world. It's the same thing with extra steps.
