Online payments firm Block has launched proof-of-reserves for its corporate Bitcoin treasury and two of its flagship products, Cash App and Square, joining a growing list of crypto companies proving their holdings onchain. 

“People shouldn’t have to trust that their bitcoin is there, they should be able to verify it,” the Jack Dorsey-led company said in a post to X after announcing the proof-of-reserves feature and other new offerings in Las Vegas on Monday.

Block said anyone can “independently confirm Block’s holdings” through on-chain signatures. “Reserves are actively controlled, not just historically observed,” it added.

The proof-of-reserves seeks to verify the 8,883 Bitcoin, worth $681.4 million, marked on Block’s balance sheet — the 14th-largest Bitcoin holding among corporate treasuries.

Proof-of-reserves became more widely adopted after the collapse of FTX in November 2022 as a transparency measure to assure customers that holdings were fully backed, secure and not at risk of misuse.

Binance, Kraken, OKX, Bitfinex and Bitget are among the largest crypto trading platforms that have adopted proof-of-reserves disclosures.

Strategy’s Saylor once said proof-of-reserves is a ‘bad idea’

Strategy, the biggest corporate holder of Bitcoin in the world, has not issued any proof-of-reserves. 

In May 2025, Strategy executive chairman Michael Saylor flagged proof-of-reserves as a security risk when asked why his company doesn’t adopt the measure, arguing that it exposes sensitive information.

“It actually dilutes the security of the issuer, the custodians, the exchanges and the investors,” Saylor said at the time. “It’s not a good idea. It’s a bad idea.”

Block also launched a Bitkey hardware wallet with a touchscreen to verify transactions while rolling out a feature on Cash App allowing certain users to have payments automatically converted into Bitcoin.

Block is also offering 5% Bitcoin cash back rewards at Square merchants and has raised customer withdrawal limits fivefold to $10,000 per day and $25,000 per week.

Dorsey is one of the biggest advocates seeking to push Bitcoin payments into the mainstream.

He previously said Bitcoin payments must see wide adoption to uphold Satoshi Nakamoto’s original vision of Bitcoin as an electronic peer-to-peer cash system.

The Bank of Japan’s (BoJ) monetary policy decision on Tuesday boosted expectations of a hike in borrowing costs by the end of the second quarter. The yen is loving it, while bitcoin remains under pressure.

The central bank kept its benchmark interest rate unchanged at 0.75% as widely expected. The decision, however, wasn’t unanimous, as three board members wanted to hike rates today itself.

The 6–3 vote split is the largest since Kazuo Ueda became governor of the central bank, indicating that more policymakers are now pushing to raise borrowing costs.

Markets price June rate hike

The central bank also raised its forecast for core inflation to 2.8% for this fiscal year, while revising economic growth projections lower to 0.5% from 1%. The rationale behind the BoJ’s hawkish tilt is largely tied to war-related disruptions in energy flows through the Strait of Hormuz, which have pushed up global energy prices and fed into inflationary pressures across energy-import-dependent economies like Japan.

Traders immediately priced in a 74% chance of a rate hike on June 16. That aligns with the consensus among Bank of Japan watchers, who had widely expected a June hike ahead of the decision, according to Bloomberg News.

Yen jumps: Another carry unwind shock ahead?

The Japanese yen rose, pushing the dollar-yen (USD/JPY) pair down nearly 0.5% to 158.95 (For major currencies, that’s a notable move). Rate hikes, or expectations of them, typically support a country’s currency, in this case, the yen.

The bitcoin-yen pair (BTC/JPY) listed on bitFlyer fell by 0.6% to 12.28 million yen, consistent with the weakness in the dollar-denominated prices, according to data source TradingView.

Trends in the Japanese yen are closely watched, given its long-standing role as a funding currency.

Sustained yen strength is often associated with risk aversion. This is because the Bank of Japan’s prolonged period of ultra-low interest rates over the past decade, including the post-COVID years, encouraged traders to borrow in yen and invest in higher-yielding assets abroad.

As a result, yen strength is often seen as triggering the unwinding of these so-called carry trades. The unwinding of yen-funded positions was widely cited as weighing on global risk assets in August 2024, when bitcoin fell from $65,000 to $50,000 over the course of a week.

It is therefore possible that growing expectations of a potential rate hike in June could renew concerns about another episode of yen carry trade unwind-driven global risk aversion.

That said, the latest available data on market flows from February suggests otherwise. Japan continued increasing its holdings of U.S. Treasury notes, indicating that yen-funded carry trades remain active.

“Japan, the largest foreign holder, raised its stockpile by +$14 billion, to $1.24 trillion, the highest since February 2022. This marks Japan’s 13th monthly purchase of the last 14 months, as Japanese institutions continue chasing higher yields overseas,” the founders of newsletter service LondonCryptoClub said.

“As we have said, there is no “JPY carry unwind” trade. Those who are talking about that don’t understand how Japanese investors operate and you should ignore them,” they added.

Acting US Attorney General Todd Blanche said the US Department of Justice and FBI are no longer targeting blockchain developers over platforms used for illegal activity, instead shifting focus to the users engaged in financial crime.

Speaking at a Bitcoin conference in Las Vegas alongside FBI Director Kash Patel and Coinbase chief legal officer Paul Grewal on Monday, Blanche said that the approach to enforcement has significantly changed under the Trump administration.

The acting attorney general explained that as long as developers have nothing to do with illicit activity, the DOJ and FBI have no reason to go after them, noting that “we have fundamentally changed the game when it comes to our investigations.”

“The basic principle is that if you are developing software, if you are a coder, if you are part of that process and you are not the third-party user, and you are not helping and knowing the third party is using what you developed to commit crimes, you are not going to be investigated and not going to be charged,” he said.

The comments mark a shift in tone from the US government, which had taken strong action against the developers of platforms like Tornado Cash. The crypto mixer and privacy protocol faced significant enforcement action over illicit activity facilitated on the platform, such as money laundering and sanctions evasion.

Tornado Cash was sanctioned by the Office of Foreign Assets Control in August 2022 before the sanctions were lifted in November 2024. Developers Roman Storm and Roman Semenov were indicted in August 2023; Storm was convicted in August 2025, while Semenov remains at large. Storm has denied any wrongdoing.

Doubts remain over DOJ’s approach

Blanche’s comments were seen as positive within the crypto community, but some argued that more work needs to be done to provide developers with clarity. 

Responding to Blanche on X, Coin Center executive director Peter Van Valkenburgh said it was a “better message than developers have heard from DOJ in recent years,” but the message still leaves room for doubt. 

“But the real question is where [the] DOJ draws the line between publishing noncustodial software and ‘helping’ or ‘knowing’ about a bad user,” he said. 

Van Valkenburgh pointed to a court case in which developer Michael Lewellen sued the DOJ for pre-enforcement clarity on whether publishing his Ethereum-based crowdfunding tool constituted money transmission.

The case was dismissed in late March, with a Texas court finding that Lewellen had failed to demonstrate that there was a credible threat of enforcement from the DOJ. 

“DOJ is publicly acknowledging that developers are still sleeping with one eye open. At the same time, DOJ is telling the courts that Lewellen should not be allowed to ask for legal clarity because there is no credible threat,” he said, adding:  

“If the law is so clear why are devs sleeping with one eye open? If the law is so clear why fight to have the case dismissed?”

The DOJ’s change in approach has been taking shape for more than a year. In April 2025, Blanche released a memo explaining how the DOJ would handle enforcement differently going forward.

The memo outlines a commitment to “ending regulation by prosecution,” under which developers will not be targeted for the actions of users of their platforms or for unwitting regulatory violations.

“I do not want any platform to look at the Department of Justice or the FBI as somebody who’s going to just cause them a lot of problems,” Blanche said at the Las Vegas conference.

Japanese crypto exchange Bitbank has launched a crypto-linked credit card that allows users to settle bills with assets held on its platform. 

The product marks a new step for crypto payments in Japan’s regulated market.

The card, named “EPOS Crypto Card for Bitbank,” was launched through a partnership with EPOS Card, the fintech arm of Marui Group. Bitbank said the service is the first in Japan to let credit card bills be settled directly from crypto exchange balances.

Bitcoin bill payments added for users

The card allows users to pay monthly credit card bills with bitcoin from their Bitbank accounts. The payment feature is currently limited to bitcoin, according to the company’s Monday release.

Bitbank said the service gives crypto holders another way to use digital assets without moving funds to another platform. The exchange and EPOS Card may consider adding more cryptocurrencies later.

Moreover, the EPOS Crypto Card for Bitbank also offers 0.5% cashback in crypto on monthly spending. Users can receive rewards in bitcoin, ether, or Aster.

The rewards will be deposited into users’ Bitbank accounts. This setup keeps the cashback inside the exchange and gives users direct access to their crypto rewards.

Japan’s crypto card market sees more activity

Bitbank’s launch follows growing activity around crypto-linked cards in Japan. Binance Japan introduced its own Binance Japan Card in January, allowing users to earn BNB from card spending.

The Bitbank card takes a different route by focusing on bill settlement from exchange-held crypto assets. The launch shows how Japanese crypto firms are adding payment services while working within local market rules.

Bitcoin bulls fell $515 short of their $80,000 target after BTC (BTC) topped out at $79,485 on Monday, but a potential upside is that the brief pullback provides a necessary retest of key underlying levels. 

In technical analysis, a break of structure is generally followed by a support-resistance retest as swing traders take profits at preset levels that align with metrics such as the Fibonacci retracement, exponential moving averages, Bollinger Bands, order book structure, and more. The support-resistance flip is also a feature traders look for to confirm that a longer-term resistance (in this case) has turned into support. When confirmed, it gives some traders the confidence to open new positions at the S/R level as they believe the break of structure and retest marks either the completion or the start of a trend reversal. 

After managing the first decisive breakout from the three-month-old channel, Bitcoin retested the channel resistance (at $76,688) that had pinned down every BTC rally since Feb. 8. A deeper retest could see the price drop to the 20-day moving average at $75,250, and then confirmation of the S/R flip would entail daily candle closes above the former trendline resistance.

Outside of the naked price action from the candlestick chart, the long-to-short delta (heatmap below) shows longs currently with the advantage, with a -$38.6 million delta, and the figure widens to -$153 million if BTC rises to $77,500.

Essentially, the SR flip from the Monday US morning session liquidated long positions down to $76,500, potentially confirming the trendline resistance as support. As the price rebounds, the chart shows shorts having significantly more leveraged exposure at risk.

Bulls may succeed in pushing the price through the most immediate overhead shorts and returning BTC to its range highs below $80,000, but the aggregate orderbook set at 2.5% to 5% shows a wall of asks stacked from $79,700 to $80,000. This suggests that clearing the $80,000 level could remain a challenge in the short-term.

Robinhood users are confronting a new phishing campaign that rides on Gmail’s native dot alias feature and weaknesses in the platform’s account-creation flow. The emails, which appear to originate from Robinhood’s mail server, warn of an unrecognized device login and direct recipients to malicious sites via a deceptive call-to-action button.

Early reports on social media show users receiving messages that look like legitimate Robinhood alerts. The attackers exploit Gmail’s dot-insensitivity to register nearly identical-looking accounts, then leverage a flaw in Robinhood’s onboarding flow to inject forged content into the automated emails. The result is an email that can slip past common defenses and prompt a user to click through to a phishing page.

Key takeaways

• The attack leverages Gmail’s dot alias behavior to route phishing emails to a target’s inbox by creating Robinhood-style accounts that differ only by a dot in the address.
• Fraudsters embed HTML instructions in the optional “device name” field during Robinhood’s account creation, which Gmail treats as formatting, enabling a seemingly legitimate email with a malicious phishing link.
• The forged message can pass standard email authentication (SPF, DKIM, DMARC), making the email appear trustworthy and increasing the likelihood of a click on the phishing button.
• Victims are at risk mainly if they enter credentials on the fake site; the mere visit does not grant access, but credential input can lead to account compromise.
• Robinhood confirmed that the incident involved abuse of the account creation flow, not a breach of its systems or customer accounts, and no personal data or funds were reported as impacted.

The exploitation mechanics

Experts describe a two-pronged method that underpins the campaign. First, scammers create Robinhood accounts using email addresses that differ only by the presence or absence of a dot in Gmail’s address handling, such as “jane.smith@gmail.com” versus “janesmith@gmail.com.” In the eyes of Robinhood, these are distinct accounts, but Gmail routes mail to the same inbox, enabling fraudsters to seed legitimate-looking communications under a target’s actual address.

Second, attackers exploit the account-creation flow by injecting HTML into the optional “device name” field. Gmail interprets field content as formatting, allowing a phony email to contain a credible header and a convincing call to action. The crafted email can pass SPF, DKIM, and DMARC checks, making it appear as though it truly originates from noreply@robinhood.com. When a recipient clicks the phishing button, they are taken to a counterfeit login page designed to harvest credentials.

Robinhood’s response and user guidance

Robinhood’s official stance was communicated through its support account on X, which acknowledged that some users received a falsified email from “noreply@robinhood.com” with the subject line “Your recent login to Robinhood.” The company attributed the issue to an abuse of the account-creation flow and stressed that there was no breach of Robinhood’s systems or customer accounts, and that personal information and funds were not impacted.

“This phishing attempt was made possible by an abuse of the account creation flow. It was not a breach of our systems or customer accounts, and personal information and funds were not impacted. If you received this email, please delete it and do not click any suspicious links. If you have clicked a suspicious link or have any questions about your account, please contact us directly within the Robinhood app or website.”

Security researchers emphasize prudence: users should avoid clicking unfamiliar links, delete suspicious messages, and contact official Robinhood channels for account questions. The episode also underscores the need for vigilance around onboarding flows and the resilience of email authentication measures, which attackers now appear capable of circumventing in targeted contexts.

Industry context and what’s next

The phishing wave hitting Robinhood arrives amid a broader trend in crypto-security risk. Hacken, a blockchain security firm, reported earlier this month that phishing and social engineering dominated crypto attacks in the first quarter of 2026, accounting for about $306 million in losses. The finding highlights a persistent vulnerability vector in the crypto ecosystem, where attackers increasingly blend social manipulation with technical exploits to bypass conventional safeguards.

For investors, traders, and builders, the episode reinforces several practical considerations. Platforms must tighten onboarding checks to prevent impersonation through dot aliases or other address-equivalence tricks, while improving email authentication and leveraging behavioral signals to distinguish genuine messages from forged ones. Users should practice heightened skepticism with any alert that requests action within a financial app, especially when a message prompts credential input or redirects to a login page. Enabling two-factor authentication, staying within official apps or websites for sign-in, and cross-checking any unusual activity with direct support channels become critical defensive habits in this environment.

Looking ahead, observers will be watching how Robinhood and other platforms shore up their onboarding processes and email security controls. Investigators will also assess whether additional victims were targeted and whether similar dot-alias techniques are leveraged in other services. For now, the incident serves as a pointed reminder that even well-known fintech apps remain vulnerable to technically simple yet highly effective social engineering plays when combined with misconfigurations in onboarding flows.

Readers should watch for updates from Robinhood on account-flow protections and for guidance from security researchers on mitigations that can be deployed both by platforms and by users to reduce exposure to this evolving tactic.

XRP finally gave way at $1.40, and the way it broke matters more than the move itself. This wasn’t a slow drift lower. It was a high-volume push that cleared a level buyers had defended for weeks. Once that kind of support goes, it usually doesn’t snap back quickly. It tends to flip, and that’s exactly the test now.

News Background

• Bitcoin dominance pushed toward 60%, reinforcing a rotation out of altcoins and limiting follow-through demand for XRP.

• The multi-month triangle structure that had been compressing price finally resolved, with the move breaking lower instead of triggering the expected upside expansion.

Price Action Summary

• XRP dropped from $1.44 to $1.39, breaking cleanly through the $1.40 support zone.
• The move was driven by a sharp spike in participation, not thin liquidity.
• Price is now stabilizing just below the breakdown level, trading in a tight $1.39–$1.40 range.

Technical Analysis

• The key shift is structural. $1.40 was support, now it’s resistance unless reclaimed quickly.
• Volume expanding into the breakdown confirms real selling pressure, not just positioning noise.
• The triangle pattern that held price for weeks has resolved lower, removing the compression support.
• Short-term bounces are showing up, but they’re reactive, not strong enough to reverse the move yet.

What traders should watch

• $1.40 is now the pivot. Reclaim it with volume, and the breakdown starts to look like a fakeout.
• $1.37 is the next downside level. Losing that opens the path toward deeper support near $1.31.
• If price keeps holding below $1.40, sellers stay in control and rallies are likely to get sold.

Canada has advanced a bill to block cryptocurrency donations in federal elections, pushing tighter controls on how political funding is handled.

According to Canada’s House of Commons, Bill C-25, known as the Strong and Free Elections Act, cleared its second reading on Friday, allowing lawmakers to move the proposal to committee for detailed review and possible amendments.

Tabled on March 26, the bill would bar political parties and candidates from accepting crypto contributions, with regulators identifying digital assets as a gap in existing campaign finance rules. Lawmakers backing the measure have linked the restriction to concerns around verifying the source of funds and enforcing contribution limits under current law.

No timeline has been set for the committee stage, leaving the pace of further progress dependent on parliamentary scheduling.

The decision to restrict crypto in elections is unfolding alongside efforts to define how digital assets fit within the financial system. Regulators have been working on stablecoin oversight frameworks that would expand the role of the central bank while refining rules for custody, investment funds, and storage practices.

Policy direction has taken shape under Prime Minister Mark Carney, who has previously expressed skepticism toward cryptocurrencies. Despite that, Canadian authorities have continued to build a structured regulatory approach, separating financial system integration from political use cases where tighter limits are now being proposed.

Crypto donations face growing scrutiny across democracies

Debate around crypto-linked political funding has intensified beyond Canada, with similar concerns raised in other jurisdictions. In the United Kingdom, the Joint Committee on the National Security Strategy warned in its March 18 report that cryptocurrency donations pose risks to transparency and national security due to difficulties in tracing their origin.

The UK committee called for an immediate halt to such donations until clearer rules are introduced, citing the possibility of foreign actors attempting to influence political outcomes. Lawmakers also proposed stricter disclosure thresholds and stronger penalties tied to foreign funding violations.

Republican US Senator Thom Tillis said he won’t support the Senate’s crypto market structure bill unless it includes ethics provisions limiting how White House officials can use crypto.

“There has to be ethics language in the bill before it leaves the Senate, or I’ll go from one of the people working on negotiating it to voting against it,” Tillis told Politico on Monday.

Democratic Senator Ruben Gallego said that there is “no final bill — there is no final movement — unless there is a bipartisan agreement when it comes to the ethics provision.”

Tillis, who is retiring early next year, is a senior member of the Senate Banking Committee, which is key to advancing the Senate bill. The House passed a version of it, called the CLARITY Act, in July.

The bill carves up crypto regulation between the Commodity Futures Trading Commission and the Securities and Exchange Commission and has been plagued by delays as lawmakers and lobbyists seek to add provisions on ethics and stablecoin yield payments.

Democratic lawmakers have heavily criticized the Trump family’s expanding crypto businesses and have sought to use the bill to crack down on a perceived conflict of interest.

Now, lawmakers are reportedly saying talks on the ethics provisions are moving forward, but it’s not clear what the language will be.

“We’re making progress,” Democratic Senator Adam Schiff told Politico. “We have been talking for a long time without making much progress, and now that other parts of the bill are starting to come together, we’re narrowing our differences.”

Schiff said earlier this year that Democrats want “a ban on sponsoring, endorsing or issuing digital assets that applies to all federal employees,” including the president, who has backed a memecoin and non-fungible tokens bearing his name and likeness.
