Ethereum could begin adding post-quantum protections to accounts for as little as $0.07, without waiting for a hard fork, according to the Ethereum Foundation’s Kohaku project lead Nicolas Consigny.

In a Saturday X post, Consigny shared a paper proposing a cheaper way for Ethereum users to protect their accounts against future quantum-computing threats. The approach adapts SPHINCS+, a post-quantum signature standard developed by the US National Institute of Standards and Technology, to work more efficiently on Ethereum.

Dubbed “SPHINCS-,” the proposal aims to reduce onchain verification costs without requiring a protocol change or precompile. Consigny described SPHINCS- as a bridge toward a future post-quantum signature system dubbed “leanSPHINCS,” which aims to further reduce verification costs through aggregation.

The proposal seeks to address the long-term risk of a quantum threat to Ethereum’s Elliptic Curve Digital Signature Algorithm with a cost-efficient solution that may be deployed before a dedicated hard fork is developed.

Future quantum computing threats stirs crypto community

In April, post-quantum startup Project Eleven awarded a prize to researcher Giancarlo Lelli for using a quantum computer to break a 15-bit elliptic-curve key.

Bitcoin’s keys are 256 bits long, significantly larger than the 15-bit key Lelli managed to crack. He derived the private key from a public key paired to it, using a variant of Shor’s algorithm, a quantum computing technique that theoretically poses a threat to the type of cryptography used by Bitcoin.

According to Glassnode, about 1.92 million Bitcoin, representing nearly 10% of the total supply, are considered “structurally unsafe” in a future quantum attack scenario. Another 4.12 million BTC, or 20.6% of the supply, are classified as “operationally unsafe” due to key or address management practices.

The analytics company estimates that the remaining 69.8% of the supply, or 13.99 million Bitcoin, remains unexposed to a quantum computing threat, broadly in line with Ark Invest’s March estimate that 65% of the supply was safe.

TLDR:

• Michael Saylor introduced BPS, CEBE BPS, and BTC Yield to standardize Bitcoin treasury company evaluation.
• Strategy holds 845,256 Bitcoin worth $54.5 billion, with BPS at 220,016 satoshis per diluted share.
• CEBE BPS drops to 118,000–134,000 satoshis after deducting $6.75B debt and $15.5B preferred stock.
• BTC Yield of 12.8% year-to-date tracks BPS growth, though critics question the metrics’ independent validity.

Michael Saylor has introduced a new framework for evaluating Bitcoin treasury companies, offering three core metrics designed to bring consistency and transparency to the sector.

The metrics; Bitcoin Per Share (BPS), CEBE BPS, and BTC Yield: aim to standardize how investors assess Bitcoin-backed corporate strategies.

Strategy, Saylor’s company, holds 845,256 Bitcoin worth $54.5 billion and serves as the primary reference model.

BPS and CEBE BPS Define the New Measurement Standard

Bitcoin Per Share (BPS) is the first metric Saylor introduced. It divides a company’s total Bitcoin holdings by its diluted share count.

Strategy’s current BPS stands at 220,016 satoshis per share. This figure reflects total Bitcoin exposure before accounting for any senior financial obligations.

CEBE BPS offers a more conservative picture for investors. It subtracts senior claims, such as debt and preferred stock, before calculating Bitcoin per share.

Strategy carries $6.75 billion in debt and $15.5 billion in preferred stock. After these adjustments, Strategy’s CEBE BPS falls between 118,000 and 134,000 satoshis per share.

Saylor explained the distinction between the two metrics clearly. He stated via X: “BPS measures Bitcoin per common share before senior claims. CEBE BPS measures Bitcoin per common share after senior claims. CEBE is the conservative risk metric. BPS is the common equity growth metric.” The gap between the two figures reflects the weight of leverage on the balance sheet.

The relevance of each metric depends on liability duration. Saylor noted that short-duration liabilities make CEBE BPS the more important figure.

Longer-duration liabilities, however, make BPS more applicable. If Bitcoin’s annual return rate exceeds the cost of capital, BPS better captures the upside available to common shareholders.

BTC Yield Tracks Bitcoin Per Share Execution Over Time

BTC Yield is the third metric in Saylor’s framework. It measures the year-to-date percentage change in BPS. Strategy’s current BTC Yield stands at 12.8% for the year. This metric helps investors track whether a company is actually growing its Bitcoin per share over time.

The concept of amplification sits at the center of this framework. Saylor noted: “The difference between BPS and CEBE BPS is Amplification.”

A company with no debt or preferred stock would see BPS equal CEBE BPS, effectively tracking Bitcoin like an ETF. As liabilities increase, the two metrics diverge, creating room to outperform Bitcoin.

Not all liabilities carry the same risk profile. Short-duration, high-cost liabilities can convert amplification into underperformance risk.

Long-duration, low-cost liabilities, on the other hand, can work in favor of common equity holders. A well-capitalized Bitcoin treasury company, therefore, holds a structural advantage when managed correctly.

Reactions to the framework have been mixed across the crypto community. Supporters praise the metrics as a step toward greater transparency in Bitcoin corporate strategy.

Critics, however, argue that the measures lack independent validation. The debate reflects broader tensions around how Bitcoin treasury operations should be evaluated and communicated to investors.

TLDR:

• BSP has explicitly banned VASPs from listing or supporting anonymity-enhancing privacy virtual assets.
• VASPs must assess tokens across six pillars including issuer background, liquidity, and legal compliance.
• Ongoing monitoring is required, with deviation thresholds set as automatic triggers for token delisting.
• Misleading disclosures, market abuse, and cybersecurity risks are grounds for immediate token suspension.

The Bangko Sentral ng Pilipinas has moved to strengthen oversight of the digital asset market in the Philippines. The BSP privacy virtual assets ban prohibits virtual asset service providers from listing or supporting anonymity-enhancing coins.

Alongside this, the central bank has ordered VASPs to adopt stricter token listing, monitoring, and delisting standards. The move marks a significant tightening of regulatory control over the fast-growing crypto sector.

BSP Sets Six-Pillar Framework for Token Listing

The BSP issued a memorandum requiring VASPs to establish a robust due diligence process for listing virtual assets. The directive was released by BSP Deputy Governor Lyn Javier and applies to all regulated platforms.

VASPs must assess each token across six defined pillars before listing. These cover issuer background, market maturity, use cases, transparency, traceability, security, liquidity, and legal compliance.

For issuer background, VASPs may review incorporation documents, financial statements, and ownership structures. Fitness checks on directors, officers, and operators of the issuing entity are also required.

VASPs must also examine potential conflicts of interest involving the issuer, other VASPs, or government officers. This level of scrutiny brings VASP standards closer to those applied to traditional financial institutions.

Market maturity factors include market capitalization, average 30-day trading volume, and issue price. The number of on-chain holders and the exchanges already supporting the asset are also considered.

VASPs must make whitepapers and project documentation readily accessible to customers. These documents should cover tokenomics, target users, supported blockchains, and relevant risk disclosures.

For transparency and security, VASPs may review the token’s underlying blockchain technology, consensus algorithm, and known vulnerabilities. Independent audits and coverage by blockchain analytics firms are also evaluation factors.

Asset-backed and fiat-backed tokens face additional scrutiny around minting, issuance, redemption, and value maintenance protocols.

Liquidity providers, withdrawal rights, and reserve composition are reviewed under the redemption and liquidity pillar.

Ongoing Monitoring and Immediate Delisting Triggers Required

Beyond listing approval, the BSP requires VASPs to conduct continuous monitoring of listed virtual assets. Platforms must set deviation thresholds that serve as automatic triggers for suspension or delisting.

Tokens that no longer meet the standards applied during initial listing must be removed. This ongoing requirement prevents platforms from treating listing as a one-time compliance exercise.

VASPs must suspend or delist tokens in cases involving adverse market developments or abnormal price movements.

Legal and regulatory non-compliance, cybersecurity concerns, and consumer protection risks also qualify as delisting grounds.

Misleading disclosures and market abuse are included in the list of immediate suspension triggers. The BSP’s framework applies a continuous risk-based lens to all listed digital assets.

The BSP privacy virtual assets ban is among the most direct provisions in the memorandum. Privacy coins, which obscure transaction details and user identities, are now explicitly prohibited from VASP platforms.

The ban targets anonymity-enhancing virtual assets that limit traceability and complicate anti-money laundering efforts. This positions the Philippines alongside other jurisdictions that have moved to restrict privacy coin access.

While the BSP outlined specific documentary requirements, it noted the list is not exhaustive. VASPs are permitted to develop their own internal listing frameworks, provided they align with BSP guidelines.

The regulator’s approach gives platforms some flexibility while maintaining baseline standards. This balance reflects a practical stance toward a market that continues to evolve rapidly.

TLDR:

• Spot Bitcoin ETFs shed $4.4B over 14 sessions before Thursday marked the first day of marginal inflows.
• Strategy added 1,550 BTC at $65,200, lifting its total treasury to 845,256 BTC amid retail panic selling.
• On-chain exchange outflows hit 6,133 BTC on Friday, signaling institutional accumulation at cycle lows.
• Oil falling to $85.25 and a US–Iran MOU draft lifted Bitcoin back to $63,600 in Friday’s relief rally.

Bitcoin bottom hunters are finding reasons for cautious optimism this week as several converging factors point to a potential market floor.

A 14-day ETF outflow streak finally snapped on Thursday, while institutional buyers quietly accumulated through the panic.

Falling oil prices tied to Iran deal progress and the anticipated SpaceX IPO are also drawing investor attention back to risk assets.

Together, these developments suggest early signs of a return to crypto markets, though confirmation remains pending.

Easing ETF Outflows and Institutional Accumulation Point to a Shift

Spot Bitcoin ETFs bled roughly $4.4 billion across a brutal 14-session outflow streak. Total AUM compressed from approximately $104 billion to $80 billion, the heaviest redemption run in over a year.

BlackRock’s IBIT and Fidelity’s FBTC absorbed the steepest selling pressure during that stretch. Spot Ether ETFs lost more than $700 million across the same period.

Thursday marked the first day of marginal inflows, snapping the negative streak entirely. The Fear & Greed Index sat at 16, deep in “Extreme Fear” territory, while the MVRV Z-score registered 0.34.

That level has historically aligned with capitulation lows in prior Bitcoin cycles. Bitcoin’s realized price near $53,500 further strengthens the case for a value entry zone.

Retail investors capitulated throughout the selloff, with Glassnode’s SOPR holding below 1.0 for most of the period. Coins changed hands at a loss, confirming broad panic among smaller participants.

Institutions, however, moved in the opposite direction. Strategy added 1,550 BTC between June 1 and June 7 at roughly $65,200, lifting its treasury to 845,256 BTC.

On-chain exchange data recorded net outflows of 4,281 BTC on Thursday and 6,133 BTC on Friday. Coins leaving exchanges typically indicate larger players moving assets into custody rather than preparing to sell.

On Hyperliquid, whales built their largest net long position in two months. The divergence between retail panic and institutional accumulation is currently at cycle extremes, a setup that has historically preceded a Bitcoin bottom.

SpaceX IPO Buzz and Falling Oil Prices Lift Risk Appetite

The anticipated SpaceX IPO is drawing fresh capital attention toward high-growth and speculative assets. Risk appetite tied to a landmark listing of that scale tends to lift sentiment across adjacent markets, including crypto.

Investors rotating into growth exposure ahead of a major IPO often broaden their positions into digital assets. That dynamic could channel incremental buying into Bitcoin at a critical technical juncture.

Oil prices falling to $85.25 per barrel after a draft US–Iran Memorandum of Understanding further improved the macro backdrop. The deal, if signed, could include suspended US oil sanctions and a Strait of Hormuz reopening.

Lower energy prices directly ease the inflation pressure that has kept the Fed sidelined. That matters for crypto, as the rate-cut narrative has been the primary macro headwind all week.

Bitcoin reclaimed $63,600 on Friday after Trump canceled threatened Iran strikes following the MOU draft. The Russell 2000 gained 3.0%, and equities staged their strongest session of the week.

However, the MOU remains unsigned, and the relief rally’s durability hinges on formal deal closure. Traders should treat the current bounce as conditional until confirmation arrives.

The macro picture remains complicated, with May CPI at 4.2% and Goldman Sachs pushing its first rate-cut forecast to late 2027.

Still, the combination of snapping ETF outflows, institutional accumulation, SpaceX IPO momentum, and easing oil prices marks a meaningful shift in tone.

Whether these signals compound into a confirmed bottom depends on the next several days of ETF flow data. For now, the setup is the most constructive it has been in two weeks.

“It doesn’t have to be done as a rulemaking,” said SEC Commissioner Hester Peirce, who has led much of the agency’s crypto work since the start of last year. In response to a question from CoinDesk, she said the SEC has exemptive authority that it routinely uses. “We can do it as a rule, but we don’t have to do it as a rule.”

In March, SEC Chairman Paul Atkins described the incoming policy as “an innovation exemption to facilitate limited trading of certain tokenized securities with an eye toward developing a long-term regulatory framework.” He said it would be “limited in time and scope, but long enough so that we can craft more durable rules that harness the full potential of these new technologies.”

More recently in May, he added: “I also think we should consider what a future-proofed framework may look like, which would take the form of notice-and-comment rulemaking and would address the ‘exchange’ definition as applied to onchain trading systems.”

CoinDesk canvassed the views of several lawyers who are former officials at the SEC, asking questions about the choice to put off formal rulemaking, and whether the interim work on this will hold up. Most agreed that the approach may not carry the highest force of SEC authority, but it’d still be difficult to put the toothpaste back into the tube if the next administration sees things differently.

Ethereum researchers are exploring a way to harden user accounts against future quantum-computing threats without waiting for a disruptive network upgrade. According to Ethereum Foundation project lead Nicolas Consigny, the “SPHINCS-” proposal could start delivering post-quantum protections for as little as $0.07 in on-chain verification costs, avoiding the need for a hard fork.

Consigny shared the idea in a Saturday post on X, linking to a technical paper hosted on Ethresear.ch. The work adapts SPHINCS+, a post-quantum signature scheme standardized by the US National Institute of Standards and Technology (NIST), to run more efficiently on Ethereum’s execution environment.

Key takeaways

• Ethereum could add early post-quantum account protections using Consigny’s “SPHINCS-” approach without requiring a hard fork.
• The proposal targets lower on-chain signature verification costs by adapting SPHINCS+ to the EVM more efficiently.
• “SPHINCS-” is positioned as a transitional step toward a future, even more cost-efficient system called “leanSPHINCS.”
• The broader objective is to reduce long-term risk to Ethereum’s current Elliptic Curve Digital Signature Algorithm (ECDSA) once quantum capabilities advance.

A bridge to post-quantum signatures on the EVM

In the X thread, Consigny points to a paper proposing “SPHINCS-,” a variant designed to make SPHINCS+ signatures cheaper to verify on Ethereum. Unlike some migration plans that require protocol changes, the proposal is intended to reduce on-chain verification costs without mandating a protocol update or a dedicated precompile.

That distinction matters for Ethereum users and developers because it aims to make post-quantum readiness possible on a shorter timeline. Hard forks are expensive in governance and coordination, and they introduce additional operational complexity for wallets, contracts, and infrastructure. A solution that can be introduced with fewer low-level changes lowers the practical barrier to moving away from purely ECDSA-based assumptions over time.

The paper’s core framing is that “SPHINCS-” can function as a bridge—a starting point that brings account protections closer to post-quantum security while the ecosystem works toward a longer-term, more optimized signature scheme.

Why Ethereum is looking beyond ECDSA

The quantum concern is straightforward: if sufficiently capable quantum computers become available, the cryptography underpinning today’s elliptic curve signatures becomes vulnerable. The article attributes the motivation directly to the long-term threat posed to Ethereum’s use of the Elliptic Curve Digital Signature Algorithm (ECDSA).

Consigny’s approach is built around the idea that post-quantum signatures should be available before the ecosystem reaches a point where a dedicated hard fork or a full replacement becomes unavoidable. In other words, the proposal is less about “solving quantum tomorrow” and more about narrowing the window of unpreparedness.

For investors and operators, this shifts the discussion from purely theoretical security to migration readiness. Even if timelines for large-scale quantum attacks remain uncertain, the key economic question becomes how quickly the network can reduce reliance on vulnerable primitives.

“leanSPHINCS” and the direction of travel

In describing SPHINCS-, Consigny also highlights a further goal: eventual migration to “leanSPHINCS.” The paper characterizes leanSPHINCS as a future system intended to cut verification costs even more, with the help of signature aggregation.

This matters because signature verification costs are not just a technical detail—they affect how feasible post-quantum security is for everyday transactions. If aggregation reduces the amount of computation or on-chain work required per authorization, it can help move post-quantum schemes from “prototype-ready” to “economically practical.”

At the same time, the bridge approach implies trade-offs: SPHINCS- is designed to improve efficiency now, but it is still framed as an interim step rather than the final end state.

Quantum risk conversations spread across Bitcoin and Ethereum

The Ethereum proposal lands in a broader wave of crypto security discussions about how quantum advancements could impact blockchain cryptography.

Earlier this year, a post-quantum research effort by Project Eleven awarded a prize to Giancarlo Lelli for work involving a quantum computer capable of cracking a 15-bit elliptic-curve key. As the article notes, Bitcoin keys are 256 bits, far larger than the example that was factored. Still, the demonstration used a variant of Shor’s algorithm—a method that is widely discussed in relation to how quantum computers could theoretically threaten certain public-key cryptosystems.

Separate from the experimental headline, blockchain analytics has also tried to quantify exposure. The article cites Glassnode’s estimates that about 1.92 million BTC (nearly 10% of supply) are considered “structurally unsafe” in a future quantum attack scenario, while another 4.12 million BTC (about 20.6%) are classified as “operationally unsafe” due to key or address management practices.

Glassnode also estimated that the remaining 69.8% (or 13.99 million BTC) appears unexposed, broadly aligning with an earlier Ark Invest estimate that 65% of Bitcoin supply was safe. While these classifications don’t eliminate uncertainty around quantum timelines, they show that market participants are treating quantum risk as something that can be managed—at least partially—through operational practices.

For Ethereum, the SPHINCS- proposal can be viewed through the same lens: rather than waiting for an emergency upgrade, developers are exploring mechanisms to reduce long-term cryptographic fragility in advance.

What to watch next is whether Ethereum implementers can validate the proposal’s practical on-chain performance in real execution conditions—particularly whether the claimed low verification cost remains consistent as systems scale—and how the community plans the longer transition toward leanSPHINCS and any eventual broader post-quantum signature rollout.

Ethereum Foundation privacy project Kohaku lead Nico said Ethereum accounts can start preparing for post-quantum risks without waiting for a hard fork. 

In a June 2026 post on X, Nico wrote, “Ethereum can already start preparing accounts for a post quantum world, without waiting for a hard fork.”

The researcher said the current cost would be about $0.07 per account. The claim points to account-level protection, not a full chain upgrade. That means users or wallet teams could add protection through smart contract logic while Ethereum developers keep working on longer-term protocol changes.

SPHINCS- targets low-cost EVM verification

The technical post on Ethereum Research describes SPHINCS-, an EVM-optimized family of stateless post-quantum signatures. The design comes from SPHINCS+ and newer work on compact hash-based signatures. Its goal is to cut on-chain verification cost without using a precompile or changing Ethereum rules.

Nico’s post says a Solidity verifier can already check a post-quantum-style signature on Ethereum at practical cost. One optimized variant, called C13, verifies at about 127,000 gas and uses a 3,704-byte signature. The research also includes a Lean 4 formal proof through Verity.

The problem it tries to solve is simple. Today, Ethereum and Bitcoin accounts rely on ECDSA signatures. Researchers warn that strong future quantum computers could break that type of cryptography. SPHINCS- uses hash-based signatures, which aim to resist those attacks.

Privacy and security remain priorities

Recent crypto.news coverage shows the proposal fits a broader Ethereum roadmap. Vitalik Buterin has discussed account abstraction, which lets wallets define how transactions are approved and paid. Moreover, account abstraction forms part of Ethereum’s short-term privacy plan with FOCIL and keyed nonces.

As previously reported, Buterin said the Ethereum Foundation would focus more tightly on long-term survival, security, privacy, openness, and censorship resistance. That same coverage said Ethereum roadmap work includes post-quantum security and formal verification as future goals.

Moreover, externally owned account signatures using ECDSA are one area exposed to future quantum attacks. For wallets, the report said native account abstraction could let accounts adopt post-quantum signature schemes once efficient options exist.

Audits and limits still matter

Nico said the design has gone through an initial review with Fable, with more audits planned. That review does not make the system final. The Ethereum Research post notes limits, including non-standard settings, bounded signature counts, and a difference between Keccak-based designs and NIST-aligned versions.

For users, the key point is that Ethereum may not need to wait for a full protocol change before wallets begin testing quantum-resistant account protection. For developers, the next steps include more review, safer wallet flows, clearer cost models, and better hardware support.

The account path matters because many funds sit in old-style addresses. A wallet-based route could let high-value accounts test protection before Ethereum adopts broader changes through later technical upgrades, proposal rounds, and wider public review.

The proposal does not mean Ethereum faces an immediate quantum attack. It also does not replace future network-level work. It does show that account-level defenses can move from research into testing today, at a cost that Nico says is low enough for wide trials.

TLDR:

• The SEC approved NYSE Arca’s rule change on June 12 to list the T. Rowe Price Active Crypto ETF
• The fund holds 5 to 15 digital assets including BTC, ETH, SOL, XRP, SHIB, DOGE, and SUI.
• Unlike spot ETFs, the fund actively targets outperformance of the FTSE Crypto US Listed Index.
• Spot XRP ETFs have already attracted $1.44 billion in inflows following their market debut.

The T. Rowe Price Active Crypto ETF has received SEC approval to list on NYSE Arca. The decision, issued on June 12, marks a new chapter in multi-asset crypto investment products.

The fund will hold between 5 and 15 digital assets, targeting long-term capital growth. It is benchmarked against the FTSE Crypto US Listed Index and aims to outperform it through active management.

SEC Clears Multi-Asset Fund With Broad Crypto Exposure

The T. Rowe Price Active Crypto ETF is structured under NYSE Arca’s Commodity Based Trust Shares framework. The SEC approved the exchange’s rule change proposal, allowing the fund to be listed and traded publicly. This approval follows a broader trend of regulators clearing diverse crypto investment vehicles.

The fund’s eligible assets span across the largest digital asset classes. These include Bitcoin, Ether, Solana, XRP, and Cardano.

Additional holdings may include Avalanche, Litecoin, Polkadot, Dogecoin, and Chainlink. Stellar, Hedera, Bitcoin Cash, Shiba Inu, and Sui are also on the eligible assets list.

Unlike single-asset spot ETFs, this product offers diversified exposure across multiple digital assets. Portfolio managers will actively rebalance holdings to pursue returns above the benchmark index. The fund uses delayed disclosures as part of its active management strategy.

The SEC noted that the proposal aligns with the Securities Exchange Act. Additional safeguards against market manipulation have been built into the structure.

The exchange will also implement enhanced firewall protections and trading halt features specific to actively managed products.

Active Management Sets It Apart From Spot ETF Products

The T. Rowe Price Active Crypto ETF differs from conventional spot ETFs in a fundamental way. Spot ETFs track a single asset passively, while this fund actively manages a basket of assets. The goal is to outperform its index, not simply mirror it.

Multi-asset products reduce concentration risk compared to single-token ETFs. Spreading exposure across 5 to 15 assets provides a buffer against sharp moves in any one coin. This structure appeals to investors seeking measured crypto exposure within a regulated wrapper.

The approval arrives as other asset managers accelerate their own crypto ETF filings. BlackRock recently submitted a Form 8-A for its Bitcoin Premium Income ETF. Analysts widely interpret that filing as a signal of an imminent launch within days.

XRP holders responded positively to news of the token’s inclusion in the fund. Spot XRP ETFs have already drawn $1.44 billion in inflows since their launch. Ripple’s CEO has separately projected the company could reach $1 billion in annual revenue before year-end.

Robert Kiyosaki has again urged followers to move away from cash and into hard assets. 

In a June 13 post on X, the Rich Dad Poor Dad author asked how much a trillion dollars is, then used the answer to attack dollar savings.

Kiyosaki wrote that “cash is trash” and said savers of dollars lose purchasing power. He told followers to consider gold, silver, Bitcoin, and Ethereum. His post framed the U.S. dollar as vulnerable because, in his view, the Federal Reserve and U.S. Treasury can create money quickly.

His trillion-dollar example also served as a simple visual for readers. By comparing one dollar per minute with the creation of new money, Kiyosaki tried to make a large number feel personal. The post did not include a detailed investment plan. It focused on the idea that cash loses value when supply expands. That framing matches his usual criticism of fiat money. It also fits his asset-focused brand publicly online.

Bitcoin and Ethereum remain under pressure

The warning arrived during a weak period for crypto markets. Bitcoin traded near $64,569 on June 14, while Ethereum traded near $1,674, according to market data. Both assets remained far below their 2025 cycle highs after a sharp June selloff.

As previously reported by crypto.news, the June crypto crash came from several pressures at once. The report cited a hawkish Federal Reserve, U.S.-Iran tensions, ETF outflows, and a leverage unwind. Bitcoin fell from above $80,000 to below $62,000 during that period, while Ethereum moved toward $1,500.

Gold and Bitcoin split safe-haven debate

Kiyosaki has often grouped gold, silver, and Bitcoin as alternatives to fiat money. His latest post also added Ethereum to that list. The argument fits his long-running view that inflation and monetary expansion reduce the value of cash savings over time.

Crypto.news has also tracked the changing relationship between Bitcoin and gold. In May, crypto.news reported that Bitcoin had outperformed gold by roughly 35% to 36% on a relative basis since the start of the 2026 Iran conflict. That report said Bitcoin acted more like a risk-sensitive alternative store of value than a classic crisis hedge.

Market stress keeps investors cautious

Recent fund flows still show caution. As previously reported, U.S.-listed spot Bitcoin ETFs recorded 13 straight trading days of net outflows from May 15 through June 3. About $4.37 billion left the products during that streak.

Ethereum also faced pressure from weak demand. As crypto.news reported on June 12, spot Ethereum ETFs lost $15.89 million on June 11, extending outflows for three sessions. ETH traded near $1,652 at that time as geopolitical risk and weak technical structure kept buyers cautious.

Kiyosaki’s post adds a familiar voice to the wider debate over cash, inflation, and scarce assets. It does not change the short-term market setup. Bitcoin and Ethereum still need stronger demand, calmer macro conditions, and better fund flows to confirm a steadier recovery.
