'Bitcoin Family' hides crypto codes etched onto metal cards on four continents after recent kidnappings

A question of high-profile kidnappings targeting cryptocurrency executives has rattled the manufacture — and prompted a quiescent information gyration among immoderate of its astir disposable evangelists.

Didi Taihuttu, patriarch of the alleged "Bitcoin Family," said helium overhauled the family's full information setup aft a drawstring of threats.

The Taihuttus — who sold everything they owned successful 2017, from their location to their shoes, to spell all-in connected bitcoin erstwhile it was trading astir $900 — person agelong lived connected the outer borderline of crypto ideology. They travel full-time with their 3 daughters and stay entirely unbanked.

Over the past 8 months, helium said, the household ditched hardware wallets successful favour of a hybrid system: Part analog, portion digital, with effect phrases encrypted, split, and stored either done blockchain-based encryption services oregon hidden crossed 4 continents.

"We person changed everything," Taihuttu told CNBC connected a telephone from Phuket, Thailand. "Even if idiosyncratic held maine astatine gunpoint, I can't springiness them much than what's connected my wallet connected my phone. And that's not a lot."

CNBC archetypal reported connected the family's unconventional retention strategy successful 2022, erstwhile Taihuttu described hiding hardware wallets crossed aggregate continents — successful places ranging from rental apartments successful Europe to self-storage units successful South America.

As carnal attacks connected crypto holders go much frequent, adjacent they are rethinking their exposure.

This week, Moroccan constabulary arrested a 24-year-old suspected of orchestrating a bid of brutal kidnappings targeting crypto executives.

One victim, the begetter of a crypto millionaire, was allegedly held for days successful a location southbound of Paris — and reportedly had a digit severed during the ordeal.

In a abstracted lawsuit earlier this year, a co-founder of French wallet steadfast Ledger and his woman were abducted from their location successful cardinal France successful a ransom strategy that besides targeted different Ledger executive.

Last period successful New York, authorities said, a 28-year-old Italian tourer was kidnapped and tortured for 17 days successful a Manhattan flat by attackers trying to extract his bitcoin password — shocking him with wires, beating him with a gun, and strapping an Apple AirTag astir his cervix to way his movements.

The communal thread: The pursuit of crypto credentials that alteration instant, irreversible transfers of virtual assets.

"It is decidedly frightening to spot a batch of these kidnappings happen," said JP Richardson, CEO of crypto wallet institution Exodus. He urged users to instrumentality information into their ain hands by choosing self-custody, storing larger sums connected hardware wallets, and — for those holding important assets — exploring multi-signature wallets, a setup typically utilized by institutions.

Richardson besides recommended spreading funds crossed antithetic wallet types and avoiding ample balances successful blistery wallets to trim hazard without sacrificing flexibility.

That rising consciousness of vulnerability is fueling a caller request for carnal extortion with security firms present racing to connection kidnap and ransom (K&R) policies tailored to crypto holders.

But Taihuttu isn't waiting for firm solutions. He's opted for implicit decentralization — of not conscionable his finances, but his idiosyncratic hazard profile.

As the household prepares to instrumentality to Europe from Thailand, information has go a changeless taxable of conversation.

"We've been talking astir it a batch arsenic a family," Taihuttu said. "My kids work the news, excessively — particularly that communicative successful France, wherever the girl of a CEO was astir kidnapped connected the street."

Now, helium said, his daughters are asking hard questions: What if idiosyncratic tries to kidnap us? What's the plan?

Though the girls transportation lone tiny amounts of crypto successful their idiosyncratic wallets, the household has decided to debar France entirely.

"We got a small spot celebrated successful a niche marketplace — but that niche is becoming a truly large marketplace now," Taihuttu said. "And I deliberation we'll spot much and much of these robberies. So yeah, we're decidedly going to skip France."

Even successful Thailand, Taihuttu precocious stopped posting question updates and filming astatine location aft receiving disturbing messages from strangers who claimed to person identified his determination from YouTube vlogs.

"We stayed successful a precise beauteous location for six months — past I started getting emails from radical who figured retired which location it was. They warned maine to beryllium careful, told maine not to permission my kids alone," helium said. "So we moved. And present we don't movie thing astatine all."

"It's a unusual satellite astatine the moment," helium said. "So we're taking our ain precautions — and erstwhile it comes to wallets, we're present wholly hardware wallet-less. We don't usage immoderate hardware wallets anymore."

The family's caller strategy involves splitting a azygous 24-word bitcoin effect operation — the cryptographic cardinal that unlocks entree to their crypto holdings — into 4 sets of six words, each stored successful a antithetic geographic location. Some are kept digitally done blockchain-based encryption platforms, portion others are etched by manus into fireproof alloy plates utilizing a hammer and missive punch, past hidden successful carnal locations crossed 4 continents.

"Even if idiosyncratic finds 18 of the 24 words, they can't bash anything," Taihuttu explained.

On apical of that, he's added a furniture of idiosyncratic encryption, swapping retired prime words to propulsion disconnected would-be attackers. The method is simple, but effective.

"You lone request to retrieve which ones you changed," helium said.

Part of the crushed for ditching hardware wallets, Taihuttu said, was a increasing mistrust of third-party devices. Concerns astir backdoors and distant entree features — including a controversial update by Ledger successful 2023 — prompted the household to wantonness carnal hardware altogether successful favour of encrypted insubstantial and alloy backups.

While the household inactive holds immoderate crypto successful "hot" wallets — for regular spending oregon to tally their algorithmic trading strategy — those funds are protected by multi-signature approvals, which necessitate aggregate parties to motion disconnected earlier a transaction tin beryllium executed.

The Taihuttus usage Safe — formerly Gnosis Safe — for ether and different altcoins, and likewise layered setups for bitcoin stored connected centralized platforms similar Bybit.

About 65% of the family's crypto is locked successful acold retention crossed 4 continents — a decentralized strategy Taihuttu prefers to centralized vaults similar the Swiss Alps bunker utilized by Coinbase-owned Xapo. Those facilities whitethorn connection carnal extortion and inheritance services, but Taihuttu said they necessitate excessively overmuch trust.

"What happens if 1 of those companies goes bankrupt? Will I inactive person access?" helium said. "You're putting your superior backmost successful idiosyncratic else's hands."

Instead, Taihuttu holds his ain keys — hidden crossed the globe. He tin apical up the wallets remotely with caller deposits, but accessing them would necessitate astatine slightest 1 planetary trip, depending connected which fragments of the effect operation are needed. The funds, helium added, are intended arsenic a semipermanent pension to beryllium accessed lone if bitcoin hits $1 cardinal — a milestone he's targeting for 2033.

The displacement toward multiparty protections extends beyond conscionable multi-signature. Multi-party computation, oregon MPC, is gaining traction arsenic a much precocious information model.

Instead of storing backstage keys successful 1 spot — a vulnerability known arsenic a "single constituent of compromise" — MPC splits a cardinal into encrypted shares distributed crossed aggregate parties. Transactions tin lone spell done erstwhile a threshold fig of those parties approve, sharply reducing the hazard of theft oregon unauthorized access.

Multi-signature wallets necessitate respective parties to o.k. a transaction. MPC takes that further by cryptographically splitting the backstage cardinal itself, ensuring that nary azygous idiosyncratic ever holds the afloat cardinal — not adjacent their ain implicit share.

The displacement comes amid renewed scrutiny of centralized crypto platforms similar Coinbase, which precocious disclosed a information breach affecting tens of thousands of customers.

Taihuttu, for his part, says 80% of his trading present happens connected decentralized exchanges similar Apex — a peer-to-peer level that allows users to acceptable bargain and merchantability orders without relinquishing custody of their funds, marking a instrumentality to crypto's archetypal ethos.

While helium declined to uncover his full holdings, Taihuttu did stock his extremity for the existent bull cycle: a $100 cardinal nett worth, with 60% inactive held successful bitcoin. The remainder is simply a premix of ether, layer-1 tokens similar solana, link, sui, and a increasing fig of AI and education-focused startups — including his ain level offering blockchain and life-skills courses for kids.

Lately, he's besides considering stepping backmost from the spotlight.

"It's truly my passionateness to make content. It's truly what I emotion to bash each day," helium said. "But if it's not harmless anymore for my daughters ... I truly request to deliberation astir them."
