Confidence is quickly eroding in the crypto sector, as it faces a wave of bankruptcies and investigations into Sam Bankman-Fried and his failed exchange, FTX, for losing and misspending billions of dollars in user deposits.

But Didi Taihuttu; his wife, Romaine; three daughters, and Teddy, a Pomeranian puppy they adopted in Portugal last year, are as confident as ever in their bet on bitcoin — they’re just changing how they store it.

Ever since liquidating all of their assets and buying bitcoin in 2017 back when it was trading at around $900, the Taihuttus have safeguarded their crypto riches in three main places: centralized exchanges, or CEXs, such as Bybit and Kraken; decentralized exchanges, or DEXs, such as Uniswap; and hardware wallets hidden in secret vaults on four different continents. But as digital asset brokers, lenders, and exchanges continue to fall into bankruptcy — locking up customer funds in the process — the Dutch family of five is proactively moving $1 million in crypto into DEXs, which allow users to hang on to custody of their tokens.

“For me, bitcoin is still about freedom, and decentralized currency should be able to be used by everyone in the world without needing to do KYC or any other regulatory stuff,” Taihuttu told CNBC, referring to the know-your-customer, or KYC compliance, required by many centralized platforms such as Coinbase. DEXs don’t require users to connect an ID or bank account to the platform, hence making it an ideal custody solution for the Taihuttus.

CNBC caught up with the 44-year-old patriarch a few days after the family made the move from Lagos, Portugal, to Phuket, an island just off the western coast of mainland Thailand in the Andaman Sea. The family is currently living on 0.3 bitcoin a month — about $5,000 — and they are buying back the bitcoin that they sold when the cryptocurrency was trading at around $55,000 a year ago. For the Taihuttus, the cascade of crypto bankruptcies and failed tokens just shows that “bitcoin is the king” and “completely different than all the other projects.”

While the Taihuttus did not have any tokens tied up with FTX, Celsius, Voyager Digital, or any of the other platforms that recently went under, the wave of failures did remind them of the importance of ownership.

In crypto, one of the mantras is “not your keys, not your coins,” meaning that rightful possession of tokens comes through the custody of the corresponding private keys. DEXs such as Uniswap and SushiSwap are peer-to-peer platforms where transactions happen directly between traders, entirely cutting out intermediaries such as banks and brokers. That means that users retain custody of their tokens by never handing over their private keys.

DEXs eliminate centralized intermediaries from financial transactions such as trading, holding and transferring assets through programmable pieces of code known as smart contracts. These contracts are written on a public blockchain such as ethereum, and execute when certain conditions are met, negating the need for a central intermediary. In essence, with DEXs, you trust code, and with CEXs, you trust people.

“You never send your bitcoin to an exchange. Your bitcoin stays in your own wallet, meaning you have complete custody of your coins,” explained Taihuttu. “You connect to a DEX, and by making that connection, you trade out of your own wallet.”

That nuance of ownership is critical.

“If the DEX collapses, it doesn’t matter, because the bitcoin are always in your own wallet,” he added.

Changing their storage strategy

From the beginning, Taihuttu said he could tell something was “really off” with FTX, even though it was one of the biggest CEXs on the planet before it imploded in November.

“Too many influencers were paid too much money to promote that one,” said Taihuttu, who added that reliable crypto products and companies typically don’t rely so heavily on celebrity endorsements.

The Dutch father of three had learned his lesson in 2017, when he lost four bitcoin to a hack of a centralized exchange known as Cryptopia.

“From that moment, I was always searching for alternatives,” he explained.

People who choose to hold their own cryptocurrency can store it “hot,” “cold,” or some combination of the two. A hot wallet is connected to the internet and allows owners relatively easy access to their coins so they can spend their crypto. The trade-off for convenience is potential exposure to bad actors.

“Cold storage often refers to crypto that has been moved to wallets whose private keys — the passwords that enable the crypto to be moved out of the wallet — are not stored on internet-connected computers, so that hackers can’t hack into the computer and steal the private keys,” said Philip Gradwell, chief economist of Chainalysis, a blockchain data firm.

Thumb drive-size devices such as a Trezor or Ledger offer a way to secure crypto tokens “cold.” Square is also building a hardware wallet and service “to make bitcoin custody more mainstream.” The Taihuttu family has largely relied on cold storage to safeguard their tokens for the last six years.

Currently, the Taihuttus keep 27% of their crypto holdings “hot” on centralized exchanges such as Bybit, a platform Taihuttu said is transparent and backed by real assets. He also keeps some tokens on Kraken, since it is one of the oldest exchanges. He refers to this crypto stash as his “risk capital,” and he uses these crypto coins for day trading and potentially precarious bets.

The other 73% of Taihuttu’s total crypto portfolio is in cold storage. These cold hardware wallets, which are spread around the globe, hold bitcoin, ether and some litecoin

The family declined to say how much it holds in crypto, but they did disclose that they are shifting $1 million worth of bitcoin, ether, litecoin, polkadot, and other tokens from these hardware wallets and centralized exchanges to decentralized exchanges.

Taihuttu said he ultimately wants to move 100% of the family’s crypto savings into DEXs and invest 15% of their net worth into upstart DEXs since he sees these decentralized platforms as the centerpiece of the next bull run. When asked why he is going all in on DEXs instead of keeping his crypto cold, Taihuttu pointed to ease of access.

DEXs allow him to connect the crypto he safeguards on thumb drives in hiding spots all over the world directly to the platform, meaning that he can make trades far more easily while still protecting his tokens.

“Our capital now is really difficult to use in trading, because then I need to send my bitcoin from my ledger into an exchange,” Taihuttu said.

The financial privacy offered by DEXs is also a huge incentive.

“You’re trading from an anonymous ledger on an exchange as an anonymous entity,” he said. “You get full access to non-KYC trading in a decentralized way on a DEX.”

Taihuttu isn’t alone in shifting his focus to DEXs. Following the FTX bankruptcy, Trezor’s sales revenue reportedly jumped 300% and billions of dollars in bitcoin fled exchanges. Meanwhile, Multicoin Capital, a crypto investment firm, told limited partners that 7% of its assets are similarly stored cold, in self-custodied wallets.

The pros and cons of DEXs

Centralized exchanges are a big part of what helped spur crypto adoption by offering new investors an easy on-ramp.

“Centralized exchanges have played a vital role in the adoption of cryptocurrency,” said Auston Bunsen, co-founder of QuikNode, which provides blockchain infrastructure to developers and companies. “With their growth came the industry’s growth.”

But in the last few years, and especially in the last six months, decentralized exchanges have grown in popularity as investors look to trade in a manner that protects their funds.

Boaz Sobrado, a London-based fintech data analyst, sees three main advantages to DEXs: they are noncustodial, meaning you don’t have to trust someone, like Sam Bankman-Fried, to store your funds for you; they are open, meaning anyone in the world can participate; and transaction data is more widely available, reducing the risk of insiders getting an edge from knowledge only they have.

Uniswap has facilitated more than $1 trillion in trading volume from around 100 million trades since it launched in 2018, according to a research note from Bank of America on June 13. Rival DEXs such as SushiSwap and PancakeSwap have also gained traction among traders, though Uniswap still accounts for around 51% of all trading volumes on DEXs year to date.

While DEXs play an important role in the digital asset ecosystem, there are a lot of reasons these decentralized platforms won’t eclipse their centralized peers any time soon, according to Alkesh Shah, Bank of America‘s head of web3, crypto and digital assets strategy.

“Centralized exchanges provide a one-stop shop for investing or trading digital assets with someone to speak to if something goes wrong — this will be critical for mainstream adoption beyond the early adopters of today,” Shah told CNBC.

Shah said that investors are likely to prefer exchanges that are more transparent about their operating practices, adding that regulated and transparent CEXs are likely to be important for mainstream adoption long-term.

Bank of America said in its June note that it expected Uniswap, in particular, to face regulatory scrutiny. The bank said it also saw the potential for the Securities and Exchange Commission to require its registration as a National Securities Exchange or broker-dealer.

“Uniswap may be unable to comply with regulatory requirements, given its inability to verify user identities, implement AML/KYC [anti-money laundering/know your customer] requirements or provide the necessary disclosures for the thousands of tokens listed on its platform,” the research note said.

Some centralized platforms are splitting the difference by offering DEX-type services, but it is unclear what sort of regulatory blowback they might ultimately face.

Meanwhile, Sobrado told CNBC that at this stage, most DEXs lose money, meaning they might not be sustainable.

DEXs are also automated market makers, meaning that the exchange pools liquidity from its users and then uses an algorithm to price the assets within that pool. Sobrado said that this model has proven remarkably resilient — but is unproven versus orderbook exchanges such as Coinbase.

Under it all, the Bitcoin Family still believes that the original cryptocurrency is a solid bet. They say they haven’t been swayed by the turmoil of the last six months.

“We seem to get that lesson every bitcoin cycle,” said Taihuttu. “It was Mt. Gox, it was banning bitcoin in China, it was banning mining. There’s drama every time.”

“But looking at the current situation: We have a huge war going on, we have a huge financial crisis, we have FTX, we have Celsius, we have a lot of bear market signals,” he said. “I think that bitcoin is really holding strong at $16,800. For me, bitcoin is still doing perfect and still doing what it always does: Being a decentralized currency that is usable by all people all over the world.”

E-quipment highlight: Haulotte E MAX rough terrain electric scissor lifts [video]

The new HS18 E MAX (called “HS5390” E MAX in the US, because we don’t know what meters are) rough terrain electric scissor lift from Haulotte can drive around your job site at full height, and with a full load.

Last week, Haulotte added the new HS5390 E MAX to its line of electric rough-terrain scissor lifts, completing the company’s existing HSE (HS electric) range of scissor lifts. The HS18, though, is unique – and not just because of its 18 meter fully extended height. The HS18 E MAX can be driven both fully extended, and fully loaded.

Two configurations of its material handling racks are available for the HSE scissors. The racks are built to suit the materials being transported, generally expected to be “panels” (think drywall, windows, etc.) or pipes.

With a load capacity of 400 kg (over 880 lbs.), Haulotte says its new HS5390 E MAX is ideal for jobs that require the transport of heavy loads across unfinished surfaces, using a series of optional attachments to offer a productive and safe solution to keeps materials organized and off the ground, minimizes the risk of trip and fall accidents.

Haulotte says its PULSEO-powered scissor lifts (“PULSEO” is Haulotte’s electric drive brand name) revolutionize the aerial industry by offering the performance of an internal combustion diesel machine in a more environmentally friendly package that can be used across the job site and in indoor or urban settings where loud, polluting diesels aren’t an option.

Electrek’s Take

This is a great example of a second-generation product doubling down on electrification and delivering significant improvements on its products without focusing on things like increased runtime (that’s the equivalent of “range anxiety” in the automotive world).

By stepping back and saying, “these things are already getting the job done time-wise, how can we make them do more in the time they already have?” Companies like Haulotte and JCB have made it infinitely easier for construction crews to put the HSE scissor lifts to work.

Mazda EZ-6 EV goes on sale with a starting price under $25,000

Mazda EZ-6 EV goes on sale with a starting price under ,000

Mazda officially opened the order books on its new Mazda EZ-6 EV and EREV versions of the car in China yesterday. And the starting price? It’s under $25,000.

Co-developed by Mazda and Chinese state-owned Changan Auto, the EZ-6 was one of two new electric offerings that debuted back in April. The other was a CX-5/0-sized crossover called the Arata, but the EZ-6 seemed closer to production, with a promised on-sale date later this year.

Well, Mazda lived up to its promise. The all-new Mazda EZ-6 is officially available for pre-order in China. And, while our sources (Chinese car blogs Autohome and CarNewsChina) are a bit fuzzy on the actual price, the translation seems to indicate a starting price of just 160,000 yuan (a tick over $22,800, as I type this).

One thing that’s less fuzzy, however, is that there are four extended range EV, or “EREV” versions of the car (read: hybrid) along with three fully electric BEV versions available for order at the pre-sales launch.

Value for money

Despite the low price, the base version of the newest Mazda get leather seating surfaces, and higher trim versions splice leather and suede (Alcantara?) together. There’s a 14-speaker Sony audio system available, too, along with 64-color ambient lighting, “zero-gravity” front seats, which means that the seats can recline to a near-flat position, and a panoramic glass roof.

The BEV model is reported to be equipped with a single electric drive motor putting out 190 kW of power (approx. 254 hp), and can be had with either a 56.1 or 68.8 kWh battery pack, good for a CLTC range of 480 km or 600 km (about 370 miles), respectively. Top speed of either model is an electronically-limited 170 km/h (105 mph).

The “EREV” model (man, do I hate that acronym) is equipped with a 93 hp 1.5L range extending ICE generator paired to a 160 kW (215 hp) electric motor and feeding electrons to a lithium iron phosphate battery. Battery range is about 80 miles, with a “maximum comprehensive range” quoted as 1301 km (approx. 808 miles).

Electrek’s Take

Mazda’s CEO, Masahiro Moro is working with Changan to, “turn Mazda’s China business around.” The EZ-6 is part of that plan, and is being called Mazda’s first “global” sedan. Despite that, it seems unlikely that the EZ-6 will ever make it to the US.

And that’s too bad. Our roads could use a little electrified Zoom-zoom.

Bidirectional charging may be required on EVs soon due to new CA law

Bidirectional charging may be required on EVs soon due to new CA law

It’s an exciting week for grid resiliency-lovers in California, as Governor Gavin Newsom followed up his earlier smart grid law and signed another law this week which may require bidirectional charging on EVs in the future – though the law has no hard timeline attached, so it may be a while before we see this happen.

Bidirectional charging refers to the capability of electric vehicles to not just take electricity from the grid to charge, but to output electricity in various forms, whether this be vehicle-to-load (plugging in devices, like the 1.8kW capability on the Kia Niro EV), vehicle-to-home (like Ford’s “Intelligent Backup Power” system), or vehicle-to-grid (like the Nissan Leaf is capable of).

While these applications may seem like a party trick, widespread use of bidirectional charging could lead to huge benefits for efficiency, grid resiliency, and enable much greater penetration of renewable electricity generation.

Most electric grids don’t really have trouble meeting the regular everyday needs of electricity consumers, it’s when big spikes happen that things get difficult. Either on a hot day when everyone is using air conditioning, or a day when electricity generation is curtailed for some reason or another, that’s when things get difficult.

And as climate change makes temperatures hotter, California’s grid is often overtaxed on the hottest summer days, which are becoming more numerous. Even worse, methane-burning fossil gas peaker plants are the highest-polluting form of electricity California consumes, and these are currently used at peak times in order to deal with high demand.

One solution to this problem is adding energy storage to the grid which can be dispatched when needed, and which can fill up when the grid is oversupplying electricity. This helps to balance out supply and demand of electricity and make everything a little more predictable.

This is why there has been a push for grid-based storage like Tesla megapacks, which represent a large source of rapidly-dispatchable energy storage.

But there’s another source of grid-connected batteries out there which was right under our nose the whole time: electric cars.

EVs, which are mostly connected to the internet anyway, could be used as a distributed energy storage device, and even called upon to help provide electricity when the grid needs it. We already see this happening with Virtual Power Plants based on stationary storage, but if cars had V2G, theoretically cars could contribute in a similar way – both saving the grid, and perhaps making their owners some money along the way via arbitrage (buying electricity when its cheap and selling it when its expensive).

The problem is, not many automakers have included V2G capabilities in their cars, and in the cars that do have it, not many manufacturers have made V2G-capable equipment, and the ones who have built it haven’t seen that many customers who are interested in spending the extra money to upgrade their electrical systems with V2G-capable equipment.

So there needs to be something to jumpstart all of that, and California thinks it might just have the thing.

New CA law might require bidirectional charging… eventually.

The idea started in 2023 when state Senator Nancy Skinner introduced a bill which would require EVs to have bidirectional charging by 2027.

As this bill made its way through the legislative process, it got watered down from that ambitious timeline. So the current form of the bill, which is now called SB 59, took away that timeline and instead gave the California Energy Commission (CEC) the go-ahead to issue a requirement whenever they see it fit.

The bill directs the CEC, the California Air Resources Board, and the California Public Utilities Commission to examine the use cases of bidirectional charging and give them the power to require specific weight classes of EVs to be bidirectional-capable if a compelling use case exists.

The state already estimates that integrating EVs into the grid could save $1 billion in costs annually, so there’s definitely a use case there, but the question is the cost and immediacy of building those vehicles into the grid.

The reason this can’t be done immediately is that cars take time to design, and while adding bidirectional charging to an EV isn’t the most difficult process, it also only really becomes useful with a whole ecosystem of services around the vehicle.

A recent chat Electrek had with DCBEL, making bidirectional chargers simpler for consumers

Even Tesla, which for years has touted itself a tech/energy company and sold powerwalls, inverters, solar panels and so on, is still only gradually trickling its bidirectional Powershare feature out onto its vehicles.

And that ecosystem has been a bit of a hard sell so far. It’s all well and good to tell someone they can make $500/year by selling energy to the grid, but then you have to convince them to buy a more expensive charging unit and keep their car plugged in all the time, with someone else managing its energy storage. Some consumers might push back against that, so part of CEC’s job is to wait to pull the trigger until it becomes apparent that people are actually interested in the end-user use case for V2G – otherwise, no sense in requiring a feature that nobody is going to use.

Electrek’s Take

Given all of these influences, we wouldn’t expect CA to require bidirectional charging any time soon. But it still gives the state a powerful trigger to pull if other efforts, like the recently-signed smart grid law, turn out not to be enough as California works to, grow, clean up, and make its grid more affordable all at the same time.

But having the force of law behind it could turn V2G into less of a parlor trick and more into something that actually makes a difference the way us EV nerds have been dreaming of for decades now (true story: Electrek once turned down Margot Robbie for an interview and instead talked to some engineers about V2G for an hour).

So, telling manufacturers that California may start mandating bidirectional charging soon means that those manufacturers will perhaps start taking V2G more seriously, particularly given the size and influence of CA’s car market. Even if the CEC doesn’t make it a requirement, the threat of it eventually becoming one means that EV-makers will probably start getting ready for it regardless.

There’s no real point to a single person discharging their car into the grid, but when millions of cars are involved, you could work to flatten out the famous “duck curve,” which describes the imbalance between electricity supply and demand. We hear a lot about “intermittency” as the problem with wind and solar, and grid storage as the solution to that, so being able to immediately switch on gigawatt-hours worth of installed storage capacity would certainly help to solve that problem. And we hope this law helps us get just a little closer to that potential future.
