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.

The Taihuttu family dressed up for Halloween in Phuket, Thailand, where they recently moved homes after receiving disturbing messages pinpointing their location from YouTube videos.

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.

Exodus CEO: U.S. buying bitcoin would be a global signal — but taxpayers shouldn’t foot the bill

“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?

One of the steel plates the Taihuttu family uses to store part of their bitcoin seed phrase. Didi etched it by hand using a hammer and letter punch — part of a decentralized storage system spread across four continents.

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.”

To throw off would-be attackers, Didi Taihuttu encrypts select words from each 24-word seed phrase — then splits the phrases into four sets of six and hides them around the world.

Didi Taihuttu

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.

Didi Taihuttu

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.

Didi, Romaine, and their three daughters live largely off-grid, managing crypto through decentralized exchanges, algorithmic trading bots, and a globally distributed cold storage system.

Didi Taihuttu

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.”

It’s time to start recommending some Tesla Powerwall alternatives [update]

It's time to start recommending some Tesla Powerwall alternatives [update]

Great batteries that aren't the Tesla Powerwall

For years, Tesla Powerwall has been the go-to recommendation for “normals” looking for a painless, low-effort experience from their first home solar and battery backup solutions. Its CEO’s recent involvement in controversial politics, however, means that people are now distancing themselves from the once-trailblazing company.

It begs the question: what other home solar battery solutions are there?

UPDATE 26JUL2025: added more options, put everything in alphabetical order.

Electricians and contractors often praise the sleek, energy-dense Tesla Powerwall, for good reasons. But the Powerwall isn’t the only top-shelf home battery on the market, but long wait times, Elon’s antics, and the proliferation of really good integrated alternatives from legacy EV brands might have you shopping for Tesla alternatives already. If that’s you, the next logical step is to re-think the brand’s solar battery offerings as well – here are some of the best options out there.

As I was putting this list together, I realized there were plenty of ways for me to present this information. “Best batteries ..?” Too opinion-based. “Cheapest batteries ..?” Too much research and a quick descent into Temu-grade nonsense. In the end, I went with the same solution I’ve been using on my 0% EV financing lists: alphabetical order, by brand. Enjoy!

Bluetti EP800 + B500

If you’re in a smaller space or renting and can’t (or don’t want to) add a hardwired battery solution to your home, Bluetti’s EP800 + B500 modular system is a sweet “middle ground” option that combines the Bluetti EP800 off-grid inverter and the company’s B500 battery packs in a floor-standing unit that can be used without a solar roof but also plays well with most rooftop PV options.

The basic EP800 + B500 package offers about 9.9 kWh of capacity for under $9,000 as I type this, and the system can scale up to nearly 20 kWh by adding more B500 packs. The system puts out 7.6 kW of power – more than enough, in other words, to keep some lights on and your fridge and foods (and meds) cold.

What’s more, it works great with Bluetti’s AC300 or AC500 gear if you want an option that’s a bit more portable if you move a lot or plan on moving soon.

EG4 14.3 kWh PowerPro

Two of the home solar installers I talked to in preparing this post mentioned the EG4 14.3kWh batteries, and its specs (on paper, at least) compare nicely with the Powerwall 3.

Battery	Usable capacity (kWh)	Continuous power output (kW)	Roundtrip efficiency	Average price per kWh*	Coupling
Tesla Powerwall 3	13.5	11.5	97.5%	$926	DC or AC
EG4 14.3kWh PowerPro	11.44	10.24	99%	$786	DC

“The EG4 PowerPro solar battery from EG4 Electronics is the strongest alternative to the Tesla Powerwall,” writes Kristina Zagame, from the home solar experts at EnergySage. “(The EG4) has a similar capacity, meaning it’ll last a similar amount of time, and a slightly lower power output, which means it won’t be able to power quite as many devices at the same time. And, based on quotes through EnergySage, EG4 batteries tend to be a bit more affordable compared to Tesla.”

Enphase IQ Battery 10

If you’re looking for a one-brand solution for EV charging and whole-home battery backup but don’t want to be “locked in” to GM or Tesla’s ecosystem, Enphase offers a full line of Made-in-the-USA solutions that could be right for you.

“Energy systems developer Enphase Energy is providing an even more holistic approach to managing home power usage with the introduction of new EV charger technology called the IQ line,” wrote Scooter doll, when the brand first introduced its EV charging solutions back in 2023. “The Enphase IQ is Wi-Fi enabled and integrates seamlessly into a customer’s existing home system that can be controlled with your phone.”

Franklin WH aPower 2

If you love the sleek, minimalistic styling of the Tesla Powerwall 3 but still prefer to spend your money elsewhere, the Franklin WH aPower 2 offers similarly sleek styling and beats the Tesla offering on usable energy storage capacity by 1.5 kWh. That’s nearly a full day of keeping a modern refrigerator running.

The Franklin is also designed to be easily retrofit into an existing solar system, but it loses out to the Powerwall on price per kWh, at $1,176 (vs. $926 for the Tesla unit).

GM Energy Home System

Arguably the most fully integrated EV + battery backup + solar option out there outside of Tesla, the GM Energy Home System promises to do everything a conventional home solar battery does, plus work seamlessly with your GM EV to provide even more flexibility – whether that means using the electric fuel stored in your EV to hold out that much longer in an emergency, or using the energy stored in your home’s solar battery to power an escape in your EV is up to you.

GM Energy and GM’s car dealers list Qmerit as their installation partner, and they’re great, but if you “already have a guy,” you can order the Home System directly from GM Energy’s website for $12,700 (as I type this).

The GM Energy Home System system includes:

GM Energy PowerBank
GM Energy PowerShift Charger
GM Energy Home Hub & Inverter

StorEn vanadium flow BESS

StorEn Vanadium Flow Batteries — Vanadium flow batteries; via StorEn Technologies.

If lithium-ion’s ten-year cycle life or overhyped fire risk makes you nervous, StorEn Technologies is developing a consumer-focused battery solution based on vanadium flow chemistry. Their system promises to last 25 years or more with no capacity loss, so you can charge and drain the battery fully each day and without stressing about wear … but there are a couple of downsides.

First, they’re not yet available to the general public – only to StorEn’s early investors in (what I understand to be) a sort of quasi-Kickstarter deal.

Second, the StorEn batteries are significantly bulkier than a Powerwall. That said, if you’ve got the room and you’re old enough to realize that 25 years isn’t actually a super long time, the StorEn solution might to be a super compelling, nearly maintenance-free setup that might outlast both your solar panels and the roof they’re mounted on.

So, remember how I started this off saying that I wouldn’t turn this into a “best batteries” post? That’s partly driven by the fact that I’m neither an electrician, a chemical engineer, or someone who’s researched thousands of end-user experience surveys to come up with whatever metrics I’d need to confidently and correctly call one battery “the best.”

Our friends and solar industry experts at EnergySage, though? They’ve got all three of those things on staff, and they really, really like the Villara VillaGrid+.

“The Villara VillaGrid+ stands out as the best battery on the market, scoring highest in EnergySage’s rigorous Equipment Rating System, explains EnergySage’s Kristina Zagame. “That said, (the Villara VillaGrid+) is not necessarily the best Tesla Powerwall alternative. It’s a very different (and much pricier) battery.”

What puts the VillaGrid+ on top? According to Zagame, it all comes down to the battery’s lithium-titanium-oxide, or LTO chemistry. “Unlike more traditional lithium-ion batteries, LTO has better recharge capabilities for longer life cycles, and doesn’t contain any carbon, which makes it extra safe. The only downside is you’ll definitely shell out more money upfront for the VillaGrid+.”

That extra money will also buy some additional peace of mind, as Villara backs its LTO batteries with a 20-year warranty compared to Tesla Powerwall and its (and just about everyone else’s) 10-year deal. I couldn’t find a price, but Villara’s other products, like VillaGrid 5.75 kWh battery, come in at nearly double Powerwall’s per kWh cost. Check out the specs, below, then let us know if you think the novel chemistry and additional warranty are worth it in the comments.

Battery	Usable capacity (kWh)	Continuous power output (kW)	Roundtrip efficiency	Average price per kWh*	Coupling
Tesla Powerwall 3	13.5	11.5	97.5%	$926	DC or AC
Villara VillaGrid+	11.5	10	98.5%	Get quote	DC or AC

Vertical Aerospace completes first ever public airport-to-airport eVTOL flight

Vertical Aerospace eVTOL completes historic airport-to-airport flight

Air taxi startup Vertical Aerospace achieved a world’s first this week, completing the first flight between two airports through public airspace for an eVTOL at the Royal International Air Tattoo in Gloucestershire, England.

The Royal International Air Tattoo (RIAT) is the world’s largest military airshow, held every July and serving as a public showcase for the latest advancements in aviation technology. It’s fitting, then, that RIAT served as setting for the Vertical VX4 prototype’s first piloted public flight.

The eVTOL aircraft flew 17 miles from the company’s Flight Test Centre at Cotswold Airport to RAF Fairford, a Royal Air Force station used by the US Air Force. The Vertical VX4 reached speeds of 115 mph, and an altitude of 1800 ft, and also marked the first landing at a public location for an aircraft of this type.

The Vertical Aerospace entry was the only battery-electric aircraft present at RIAT 2025, and the flight served as a demonstration of the company’s broader strategy to unlock new hybrid-electric applications for defense, logistics, and special/close support missions where the eVTOL’s (relatively) quiet operations could give it a tactical advantage.

“RIAT is a global stage for the most advanced, mission-ready aerospace technology, and we’re proud to showcase how electric aviation will support the future of defense,” says Stuart Simpson, CEO of Vertical Aerospace. “Our hybrid-electric roadmap unlocks new capabilities for military operations, and Vertical’s RIAT presence reinforces our commitment to playing a meaningful role in the future of military and special mission aviation.”

Vertical’s VX4 debuted last year, with a 20% increase in the power-to-weight ratio that enables a top cruising speed of 150 mph and transports four passengers plus a pilot up to 100 miles on a single charge.

The inaugural VX4 flight was witnessed by several thousand UK aircraft enthusiasts, and showed how an eVTOL aircraft could integrate with real-world airport operations, building momentum toward more regular, certified deployment.

Electrek’s Take

Archer, BETA, EHang, Joby, XPeng – the list of eVTOL manufacturers seems to be as long as the list of new electric car brands that didn’t exist back when I first started working with EVs back in ::gulp:: the 1990s. The future of regional point-to-point air travel certainly seems to be vertical, and electric.

Honda takes a page from Tesla playbook, launches new insurance business

Honda launches in-house insurance agency for U.S. drivers

Say what you will about Elon Musk, but Tesla has changed the way that millions of people buy cars and, by extension, car insurance. Now, Honda is taking a page from Tesla’s successful playbook and launching its own in-house insurance business. Enter: Honda Insurance Solutions.

Honda Insurance Solutions is being launched as a fully licensed insurance agency serving the insurance needs of Acura and Honda customers, but it’s not stopping at competitive pricing and coverage options for Honda cars and motorcycles. Honda Insurance Solutions promises to go several steps beyond Tesla’s offering with coverage for trailers, RVs, homes, and even pets.

“Honda Insurance Solutions offers customers access to coverage through a brand they know and trust,” says Petar Vucurevic, President, American Honda Insurance Solutions, LLC and Senior Vice President, American Honda Finance Corporation. “Insurance is a key touchpoint in the vehicle ownership journey, and we aim to deliver a superior experience tailored to the unique needs of each customer, while promoting safer driving and increased peace of mind on the road.”

The company says the launch of its new insurance business is just part of Honda’s broader digital vehicle sales platform strategy, with future plans to integrate insurance offerings into new products.

Electrek’s Take

It’s important to note some of the key differences between Honda’s insurance offering and Tesla’s. Honda isn’t offering discounts, they’re not bundling insurance premiums into the vehicle financing, and they’re not building their insurance offerings into their dealerships’ checkout/F&I offices. Not yet, anyway.

What Honda is doing right now is deepening relationships with its existing customers and finding ways to make money on products it hasn’t sold them – whether that’s the Harley parked in the garage next to their Prologue or the garage itself.

It’s a smart play. And, once Honda figures out a way to cut franchise dealers out entirely and go to a direct sales model, it’ll look even smarter.
