A wave of high-profile kidnappings targeting cryptocurrency executives has rattled the industry — and prompted a quiet security revolution among some of its most visible evangelists.

Didi Taihuttu, patriarch of the so-called “Bitcoin Family,” said he overhauled the family’s entire security setup after a string of threats.

The Taihuttus — who sold everything they owned in 2017, from their house to their shoes, to go all-in on bitcoin when it was trading around $900 — have long lived on the outer edge of crypto ideology. They travel full-time with their three daughters and remain entirely unbanked.

Over the past eight months, he said, the family ditched hardware wallets in favor of a hybrid system: Part analog, part digital, with seed phrases encrypted, split, and stored either through blockchain-based encryption services or hidden across four continents.

“We have changed everything,” Taihuttu told CNBC on a call from Phuket, Thailand. “Even if someone held me at gunpoint, I can’t give them more than what’s on my wallet on my phone. And that’s not a lot.”

CNBC first reported on the family’s unconventional storage system in 2022, when Taihuttu described hiding hardware wallets across multiple continents — in places ranging from rental apartments in Europe to self-storage units in South America.

As physical attacks on crypto holders become more frequent, even they are rethinking their exposure.

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

One victim, the father of a crypto millionaire, was allegedly held for days in a house south of Paris — and reportedly had a finger severed during the ordeal.

In a separate case earlier this year, a co-founder of French wallet firm Ledger and his wife were abducted from their home in central France in a ransom scheme that also targeted another Ledger executive.

Last month in New York, authorities said, a 28-year-old Italian tourist was kidnapped and tortured for 17 days in a Manhattan apartment by attackers trying to extract his bitcoin password — shocking him with wires, beating him with a gun, and strapping an Apple AirTag around his neck to track his movements.

The common thread: The pursuit of crypto credentials that enable instant, irreversible transfers of virtual assets.

“It is definitely frightening to see a lot of these kidnappings happen,” said JP Richardson, CEO of crypto wallet company Exodus. He urged users to take security into their own hands by choosing self-custody, storing larger sums on hardware wallets, and — for those holding significant assets — exploring multi-signature wallets, a setup typically used by institutions.

Richardson also recommended spreading funds across different wallet types and avoiding large balances in hot wallets to reduce risk without sacrificing flexibility.

That rising sense of vulnerability is fueling a new demand for physical protection with insurance firms now racing to offer kidnap and ransom (K&R) policies tailored to crypto holders.

But Taihuttu isn’t waiting for corporate solutions. He’s opted for complete decentralization — of not just his finances, but his personal risk profile.

As the family prepares to return to Europe from Thailand, safety has become a constant topic of conversation.

“We’ve been talking about it a lot as a family,” Taihuttu said. “My kids read the news, too — especially that story in France, where the daughter of a CEO was almost kidnapped on the street.”

Now, he said, his daughters are asking difficult questions: What if someone tries to kidnap us? What’s the plan?

Though the girls carry only small amounts of crypto in their personal wallets, the family has decided to avoid France entirely.

“We got a little bit famous in a niche market — but that niche is becoming a really big market now,” Taihuttu said. “And I think we’ll see more and more of these robberies. So yeah, we’re definitely going to skip France.”

Even in Thailand, Taihuttu recently stopped posting travel updates and filming at home after receiving disturbing messages from strangers who claimed to have identified his location from YouTube vlogs.

“We stayed in a very beautiful house for six months — then I started getting emails from people who figured out which house it was. They warned me to be careful, told me not to leave my kids alone,” he said. “So we moved. And now we don’t film anything at all.”

“It’s a strange world at the moment,” he said. “So we’re taking our own precautions — and when it comes to wallets, we’re now completely hardware wallet-less. We don’t use any hardware wallets anymore.”

The family’s new system involves splitting a single 24-word bitcoin seed phrase — the cryptographic key that unlocks access to their crypto holdings — into four sets of six words, each stored in a different geographic location. Some are kept digitally through blockchain-based encryption platforms, while others are etched by hand into fireproof steel plates using a hammer and letter punch, then hidden in physical locations across four continents.

“Even if someone finds 18 of the 24 words, they can’t do anything,” Taihuttu explained.

On top of that, he’s added a layer of personal encryption, swapping out select words to throw off would-be attackers. The method is simple, but effective.

“You only need to remember which ones you changed,” he said.

Part of the reason for ditching hardware wallets, Taihuttu said, was a growing mistrust of third-party devices. Concerns about backdoors and remote access features — including a controversial update by Ledger in 2023 — prompted the family to abandon physical hardware altogether in favor of encrypted paper and steel backups.

While the family still holds some crypto in “hot” wallets — for daily spending or to run their algorithmic trading strategy — those funds are protected by multi-signature approvals, which require multiple parties to sign off before a transaction can be executed.

The Taihuttus use Safe — formerly Gnosis Safe — for ether and other altcoins, and similarly layered setups for bitcoin stored on centralized platforms like Bybit.

About 65% of the family’s crypto is locked in cold storage across four continents — a decentralized system Taihuttu prefers to centralized vaults like the Swiss Alps bunker used by Coinbase-owned Xapo. Those facilities may offer physical protection and inheritance services, but Taihuttu said they require too much trust.

“What happens if one of those companies goes bankrupt? Will I still have access?” he said. “You’re putting your capital back in someone else’s hands.”

Instead, Taihuttu holds his own keys — hidden across the globe. He can top up the wallets remotely with new deposits, but accessing them would require at least one international trip, depending on which fragments of the seed phrase are needed. The funds, he added, are intended as a long-term pension to be accessed only if bitcoin hits $1 million — a milestone he’s targeting for 2033.

The shift toward multiparty protections extends beyond just multi-signature. Multi-party computation, or MPC, is gaining traction as a more advanced security model.

Instead of storing private keys in one place — a vulnerability known as a “single point of compromise” — MPC splits a key into encrypted shares distributed across multiple parties. Transactions can only go through when a threshold number of those parties approve, sharply reducing the risk of theft or unauthorized access.

Multi-signature wallets require several parties to approve a transaction. MPC takes that further by cryptographically splitting the private key itself, ensuring that no single individual ever holds the full key — not even their own complete share.

The shift comes amid renewed scrutiny of centralized crypto platforms like Coinbase, which recently disclosed a data breach affecting tens of thousands of customers.

Taihuttu, for his part, says 80% of his trading now happens on decentralized exchanges like Apex — a peer-to-peer platform that allows users to set buy and sell orders without relinquishing custody of their funds, marking a return to crypto’s original ethos.

While he declined to reveal his total holdings, Taihuttu did share his goal for the current bull cycle: a $100 million net worth, with 60% still held in bitcoin. The rest is a mix of ether, layer-1 tokens like solana, link, sui, and a growing number of AI and education-focused startups — including his own platform offering blockchain and life-skills courses for kids.

Lately, he’s also considering stepping back from the spotlight.

“It’s really my passion to create content. It’s really what I love to do every day,” he said. “But if it’s not safe anymore for my daughters … I really need to think about them.”

The rare-earth miner MP Materials will enjoy growing strategic value to the U.S., as geopolitical tensions with China make the supply of critical minerals more uncertain, according to Morgan Stanley.

The investment bank upgraded MP Materials to the equivalent of a buy rating with a stock price target of $34 per share, implying 32% upside from Friday’s close.

MP Materials owns the only operating rare earth mine in the U.S. at Mountain Pass, California. China dominates the global market for rare earth refining and processing, according to Morgan Stanley.

“Geopolitical and trade tensions are finally pushing critical mineral supply chains to top of mind,” analysts led by Carlos De Alba told clients in a Thursday note. “MP is the most vertically integrated rare earths company ex-China.”

Beijing imposed export restrictions on seven rare earth elements in April in response to President Donald Trump’s tariffs. It has kept those restrictions in place despite trade talks with U.S.

Trump removed some restrictions Wednesday on the Defense Production Act, which could allow the federal government to offer an above market price for rare earths. MP Materials is the best positioned company to benefit from this, according to Morgan Stanley. Its shares rose more than 5% on Thursday.

MP Materials is developing fully domestic rare earth supply chain in the U.S. and plans to begin commercial production of magnets used in most electric vehicle motors, offshore wind wind turbines, and the future market for humanoid robots, according to Morgan Stanley.

The investment bank expects MP Materials to post negative free cash flow this year and in 2026, but the company has a strong balance sheet should accelerate positive free cash flow from 2027 onward.
