The Bitcoin Development Mailing List, a key communication platform for developers of the original blockchain, was briefly offline on Wednesday after an apparent bot attack.

Google flagged the publicly viewable group as containing “spam, malware, or other malicious content.” Users accessing the group received a “permanently removed” message while the issue was being sorted out.

The active group is used to discuss Bitcoin proposals, relay development messages, and flag and solve any issues across the Bitcoin ecosystem. It moved to Google in February 2024. Its previous hosts were the Linux Foundation, Oregon State University Open Source Lab’s infrastructure and SourceForge.net.

“Apparently we’re “permanently removed”. Our transgression? We’re “unwanted content,” developer Ruben Somsen posted on X. “Really Google? Open source development is “unwanted”?”

Google’s Workspace Support resolved the issue early Thursday, according to an X post. It did not provide a clear reason for the removal.

Reports suggested the takedown could have been due to a bot attack, where a malicious actor performs an extremely high number of tasks (such as clicks or visits) to disable a service and create havoc within a specific environment.

The intrusion comes as the bitcoin (BTC) price grapples with high volatility amid a shaky macroeconomic environment, stemming from a slew of U.S. tariffs announced Wednesday.

Bitcoin blockchain’s hashrate is surging, revealing a growing dislocation between the network activity and prices for its native token bitcoin (BTC).

On a 14-day moving average, the hashrate, representing the computational power required to mine a block on the proof-of-work Bitcoin blockchain, recently reached an all-time high of 838 exahashes per second (EH/s), and on a 24-hour time frame, it spiked to 974 EH/s, the second highest level ever, according to Glassnode data.

Measuring over a 24-hour window can be misleading due to block time variability, so longer timeframes give more reliable insights. In two days, Bitcoin’s difficulty adjustment — which recalibrates every 2016 blocks to maintain a 10-minute block interval — is expected to increase by over 3%, reaching a new peak.

This divergence between hash rate and price is notable. While bitcoin remains about 25% below its all-time high, mining costs continue to rise. For miners to stay profitable and cover operational expenses and capital expenditures, a strong bitcoin price, full blocks and high transaction fees are essential.

Currently, miners earn revenue through two channels: block rewards (3.125 BTC per block in the current epoch) and transaction fees. However, transaction fees are extremely low — averaging around 4 BTC per day, or roughly $377,634. As bitcoin’s block subsidy continues to halve every four years, sustained or increasing transaction activity will be critical to maintaining mining incentives.

Near empty blocks

Developer Mononaut, from Mempool, recently noted that Foundry USA Pool mined the emptiest “non-empty” block in over two years, containing just seven transactions — a rarity only surpassed by a block with four transactions back in January 2023.

In other words, while the rising hashrate paints a picture of a booming network, the near-empty blocks make it the case of a powerful train speeding down the tracks but without passengers.

That’s a cause for concern for Nicolas Gregory, creator of the Mercury Layer and a former Nasdaq Board Director.

“Half-empty bitcoin blocks tell a tale — hawking the store-of-value line could scupper its future,” Gregory said on X.

“I hope bitcoiners realize this space is more than just podcasts, spaces, and the ‘number go up’ digital gold narrative. If we don’t get people using bitcoin for real commerce, it’s game over,” Gregory added.

HONG KONG—It was a battle of stablecoin issuers Thursday afternoon in Hong Kong, with Justin Sun, the founder of the Tron blockchain, and First Digital Trust (FDT), a Hong Kong-based fiduciary, holding press conferences over allegations of fund misappropriation involving Techteryx’s TrueUSD reserves.

Sun doubled down on claims that TrueUSD’s reserves were “misappropriated by a few bad actors,” leading to him needing to quietly bail out the stablecoin.

Sun pointed a finger the Hong Kong regulatory framework surrounding trusts, arguing at the press conference that loopholes and loose rules allowed the alleged misappropriation to occur.

“This situation highlights a serious challenge to the integrity of the financial system that must be addressed,” he said. “I found it hard to believe the scale of fraud orchestrated by a long list of licensed intermediaries.”

Sun even said that for the time being, Hong Kong trust companies should be avoided entirely, and urged regulators to take decisive action to safeguard the city’s global financial reputation.

For that case, Sun might have an ally in the shape of Hong Kong lawmaker Johnny Ng — called the city’s Web3 politician. He released a statement saying that he’s aware of multiple reports this year of alleged fraud exploiting trust companies, and acknowledged that local regulation needs to be improved.

First Digital Trust denies all allegations

After Sun’s press conference, First Digital Trust held its own event on X, with CEO Vincent Chok saying Sun had yet to produce “one solid piece of evidence” to back up his claims.

FDT followed its fiduciary duties, acted in clients’ best interests, complied with instructions from Sun and his nominees, which were signed off by Techteryx directors, and noted that the company is subject to third-party audits, Chok said.

Chok, however, acknowledged he was previously unaware of the familial connection between Aria CFF and Aria DMCC — the funds where TUSD’s reserves are held up.

In a complaint to the Department of Justice, Techteryx noted that Aria CFF, the fund it said is authorized to hold TrueUSD’s reserves is managed by Matthew Brittain. Aria DMCC, which Techteryx said is unauthorized, is controlled by his spouse, Cecilia Brittain.

Chok said FDT is working to recover funds, but know-your-customer (KYC) and anti-money laundering (AML) issues involving the ultimate beneficial owner of Techteryx are apparently holding things up.

He also rejected Sun’s claims in a post on X that First Digital Trust is unable to fulfill redemption obligations of its FDUSD stablecoin. The token is still very much solvent, Chok said.

FDT said it plans to pursue legal action over Sun’s claims.

Earlier, the company posted examples of on-chain data showing redemptions going through.

U.S. recession fears are in the air following President Donald Trump’s tariff plan, with prediction platforms Polymarket and Kalshi indicating heightened concerns the economy will take a hit.

On Polymarket, a decentralized prediction platform, the chance of the country slipping into recession this year topped 50% for the first time since the betting contract “US Recession in 2025” began trading early this year. The contract’s Yes shares soared to over 50 cents from 39 cents in less than 24 hours.

The contract will resolve to Yes if the National Bureau of Economic Research (NBER) confirms a recession at any point before Dec. 31. The other condition requires back-to-back quarterly contractions in gross domestic product.

Kalshi, a U.S.-based regulated prediction market, also points to heightened economic concerns among traders, with the probability of a 2025 recession rising to 54% from 40% .

Financial markets tend to be forward-looking and may react to rising U.S. recession odds by sending risk assets such as bitcoin (BTC) and other cryptocurrencies lower. At publication time, the S&P 500 futures traded 3% lower, pointing to severe risk aversion on Wall Street and offering bearish cues to bitcoin, which changed hands at $83,100, 1.5% lower in 24 hours.

The sweeping tariffs unveiled Wednesday set a base rate of 10% on all imports, plus higher taxes on 60 nations identified as worst offenders. China, the most heavily hit, warranted a 34% levy on top of the existing 20% charge, taking the total to 54%. The base tariffs go into effect on April 5 and the higher reciprocal rates on April 9.

While the Trump administration expects tariffs to rectify the large and persistent U.S. goods trade deficits, in the short run, they could add to domestic inflation and global instability. The latter could happen immediately if China, the European Union and others hit back with higher tariffs, starting a full-blown global trade war.

Risk-off to be short-lived?

Still, some observers say the tariff uncertainty might lead only to an economic slowdown rather than a full-blown recession.

“The threat of further tariff escalation remains a key concern, but our economic forecasts do not call for a recession in the US,” UBS said in a blog post. “In our base case, a wide range of selective tariffs and counteractions are likely to lead to slower economic growth compared to last year, but they should not prevent the US economy from expanding by around 2%—its historical trend rate—this year.”

As for financial markets, some observers say the tariffs are dovish, meaning the initial risk-off reaction could be short-lived and quickly reversed by expectations of Federal Reserve interest-rate cuts.

“Remember – tariffs are dovish, and big tariffs are very dovish,” Joseph Wang, operator of the research portal fedguy.com said on X, referring to his November post that detailed how big tariffs would lead to more rate cuts.

Wang argued that while tariffs are inflationary, they can be mitigated through foreign-exchange rates and are ultimately transitory. Meanwhile, damage to the business sentiment can be long-lasting, leading to unemployment, which the Fed would want to avoid.

Rates traders are already pricing a higher probability that the Fed will cut the benchmark borrowing cost in June, restarting the so-called easing cycle that began in September last year.

Over $100 million in Ripple USD (RLUSD) has been issued since April 1, among the highest levels in recent months, as demand for the relatively new stablecoin heats up.

A $50 million tranche of RLUSD was issued earlier this week on Tuesday, with another $50 million late Wednesday. That came as Ripple added the stablecoin to its official payments product, with payment providers BKK Forex and iSend already said to be using the stablecoin.

Industry leaders expect RLUSD to further shift crypto market dynamics, where upstarts tether (USDT) and USD Coin (USDC) could see competition from Ripple’s product.

XRP Ledger-based decentralized financial (DeFi) applications could be a cohort to watch for as RLUSD gains traction on various platforms, boosting XRP token demand.

RLUSD is a stablecoin pegged 1:1 to the U.S. dollar, offered on the XRP Ledger and Ethereum blockchain. It is fully backed by U.S. dollar deposits, short-term U.S. Treasuries, and cash equivalents.

To maintain its peg, RLUSD relies on a 1:1 reserve system—each token matches an equivalent fiat value.

Users can mint RLUSD by depositing dollars with authorized partners, who issue tokens, or burn RLUSD to redeem cash. Market arbitrage helps stabilize its price: if RLUSD trades below $1, traders buy it to redeem at par, raising demand; if above $1, they mint more, increasing supply.

Security features make RLUSD appealing to institutional users. An XRP Ledger amendment in January saw a “clawback” feature go live on the network, allowing the issuer to reclaim or “claw back” certain tokens, such as RLUSD, from users’ wallets under specific conditions.

This feature is typically implemented for regulatory compliance, to recover assets in cases of fraud, illegal activities, or when tokens are sent to unintended addresses.

Higher-than-usual market volatility affected bulls and bears alike as crypto futures racked up $450 million in liquidations in the past 24 hours as U.S. tariffs went into play.

President Donald Trump officially levied a 25% tariff on auto imports and a minimum 10% tariff on all exporters to the US. Additional duties were imposed on the nation’s biggest trading partners in Asia and the European Union, with China facing a 50% hike on several goods and a 26% fee on some Indian goods.

Turmoil in markets ensued with gains from the past three days wiped out in U.S. indices and cryptocurrencies. Asian markets tumbled early Thursday and U.S. 10-year Treasury yields slumped to the lowest level in more than five months. Gold set yet another record high.

Bitcoin inched above $87,000 as investors hoped for leaner long-term effects of the economic changes, with signs of a risk-on environment emerging at the start of the week. Majors ether (ETH) and xrp (XRP) traded above $1,900 and $2.15, respectively, with technical analysis suggesting higher moves in the near term.

But the euphoria was short-lived as crypto majors dipped as much as 5% from Wednesday’s highs before gradually stabilizing.

In Asian morning hours on Thursday, bitcoin traded just above $83,500 while ether traded slightly over $1,800 — effectively reversing all gains from Tuesday after a sudden drop following the Tokyo open.

That caused over $230 million in liquidations on both bullish and bearish bets, data shows, in an unusual move. BTC-tracked futures registered over $172 million in long and short liquidations alone, followed by ETH futures at $120 million and smaller altcoins at $50 million.

Liquidation refers to when an exchange forcefully closes a trader’s leveraged position due to a partial or total loss of the trader’s initial margin. It happens when a trader is unable to meet the margin requirements for a leveraged position (fails to have sufficient funds to keep the trade open).

Single-sided large liquidations can signal the local top or bottom of a steep price move, which may allow traders to position themselves accordingly. However, Thursday’s liquidations can be considered a sign of market uncertainty.

Tariffs-led risk-off has payments-focused cryptocurrency XRP trading close to the support zone near $2, a crucial level for confirming a significant topping pattern and renewed downtrend.

We are referring to the head-and-shoulders pattern, comprising three peaks, with the middle being the highest. A horizontal line drawn from the base of the three peaks, the neckline, marks the key demand zone.

In XRP’s case, the $1.90-$2 range has been that demand zone since January. So, a price move below the same would trigger the H&S breakdown, confirming a bullish-to-bearish trend change.

A potential breakdown could see prices nearly halve to $1.07, according to veteran analyst and trader Peter Brandt. Chart analysts identify targets using the measure move method, which involves determining the distance from the top of the head to the neckline and subtracting that distance from the breakdown point, in this case, $2.

On the higher side, $3, or the lower high created in early March, is the level to beat for the bulls.

It’s a risk-off day in Asia as traders look to Beijing’s response to U.S. President Donald Trump’s sweeping reciprocal tariffs on China and other Asian nations.

On Wednesday, Trump announced reciprocal tariffs on imports from 180 nations, including higher taxes on trading partners identified as worst offenders, such as China and the European Union.

Trump imposed a new 34% tariff on goods from China in addition to the existing 20% tax, bringing the total levy to 54%, the highest for any nation. Meanwhile, the latest action did not affect Canada and Mexico.

Observers say the ball is now in China’s court, and the nature of its retaliation could determine the market reaction.

“Everything now depends on China. If China devalues the Yuan in response to today’s large, additional US tariffs, that sets off a global risk-off that hits EMs first and then – if it persists – spills back to the US. China has so far kept a very low profile. That may now end,” Robin Brooks, managing director and chief economist at the International Institute of Finance, said on X.

Early Thursday, Beijing urged the U.S. to lift tariffs while vowing retaliation immediately. Meanwhile, the Chinese yuan dropped to a seven-week low of 7 RMB/USD alongside losses in the Asian equities and an impending death cross on bitcoin (BTC).

Letting the yuan depreciate, which makes Chinese goods more attractive in international markets, is one way to counter Trump’s tariffs. That said, it could spell trouble for carry (currency) trades and scare financial markets, as observed in 2015 and 2018.

Besides, potential intervention by the People’s Bank of China (PBoC) to stall a rapid yuan decline can boost the dollar index, inadvertently weighing over risk assets, including stocks and cryptocurrencies.

It’s no coincidence that Asian equities traded in the red at press time, with Japan’s Nikkei hitting an eight-month low. The U.S. stock futures fell over 2%, pointing to risk-off mode.

Bitcoin (BTC), the leading cryptocurrency by market value, traded near $83,300, having dropped from $88,000 to $82,500 following Trump’s tariffs announcement, according to CoinDesk market data.

The 50-day simple moving average (SMA) of the cryptocurrency’s spot price appears on track to cross below its 200-day SMA, confirming what is known as the “death cross” bearish technical pattern.

Though it has a mixed record of predicting price trends, the latest cross happening against the backdrop of escalating trade tensions warrants attention – more so, as options pricing now shows bias for puts or downside protection out to the June end expiry, according to Deribit and Amberdata.

U.S. stablecoin legislation took another major step on Wednesday as a House of Representatives committee joined Senate counterparts in advancing a bill to be considered by the overall House, bringing stablecoin regulations closer to reality.

Eventual approvals in both the overall House and Senate would let lawmakers start melding the two versions into a unified piece of legislation that could get a final nod. Republican lawmakers and President Donald Trump have aimed toward an August goal in getting the effort completed.

Though the crypto industry and their most reliable Republican allies in Congress were happy to welcome many Democrats to the yes side on moving the Stablecoin Transparency and Accountability for a Better Ledger Economy (STABLE Act) out of the House Financial Services Committee on Wednesday, the Democrats on the panel consistently raised concerns about Trump’s connections to the industry and stablecoins.

A week before the House committee focused on the bill in Wednesday’s markup — a session in which lawmakers make changes and debate amendments on legislation — the Trump-tied World Liberty Financial (WLFI) announced it’s supporting its own stablecoin (USD1). Trump has been highly active in crypto, including in selling non-fungible tokens (NFTs) and memecoin $TRUMP, even as he pushes for crypto-friendly policies at the federal level.

U.S. regulation of stablecoins — generally dollar-tied tokens, such as Tether’s USDT and Circle’s USDC — is one of the two top policy priorities for the industry. And committee Chairman French Hill argued on the industry’s behalf that “innovation needs guardrails, not roadblocks.”

Republican members declined to discuss President Trump’s industry involvement in any explicit terms. When Waters and other Democrats pushed amendments to block the potential conflicts raised by the president’s business interests and his direct authority over regulators who would make decisions about stablecoins, they were rejected by the panel’s Republicans, who repeatedly called such protections “unnecessary.”

“We don’t discriminate on entrepreneurs based on who they are and where they come from,” Hill said. If the government wants clear guardrails around this space, he repeatedly argued, the best move is to pass the bill that establishes oversight.

Representative Maxine Waters, the senior Democrat on the panel, said that Trump “leveraged the power of the presidency to establish multiple crypto schemes to enrich himself and his family,” calling it a “display of greed.”

“He’s unlike any other issuer, because he’s the president of the United States,” said Representative Stephen Lynch, the ranking Democrat on the panel’s digital assets subcommittee, who argued Trump would be in a position to sign off on any government help needed by his own business interests were they to fail. “If this was a Democratic president who was trying to do this, the Republicans’ hair would be on fire, and rightly so. This should not be happening.”

Another Democrat, Illinois Representative Sean Castin, argued that Tron’s Justin Sun has put tens of millions of dollars into WLFI for no clear return other than its relationship to the Trump family. He contended that government officials tied to stablecoins could be influenced by foreign investors in a way that’s hidden from public scrutiny.

The Democratic arguments failed to move the committee’s Republican majority, so no new amendments stuck to the effort. Supporters have said this House version is largely parallel to the Senate’s. Representative Bill Huizenga, a Michigan Republican, said the House version properly maintains sufficient authority in the hands of state regulators, which offers a “lighter touch, at times.”

“We have an administration that is ready to embrace these products, and the time is now,” Huizenga said.

This was one of a few bills before the House Financial Services Committee dealing with crypto-tied topics. Another piece of legislation debated on Wednesday was one that would form a cross-government group of law-enforcement agencies to address illicit crypto use and another that would ban U.S.-issued central bank digital currency (CBDC). Lawmakers also voted on dozens of amendments to the stablecoin bill before voting to advance the bill itself, though they initially had difficulties with their electronic voting system.

As the stablecoin bill continues to move forward, Trump is also poised to sign the first pro-crypto congressional action: a resolution that erases an Internal Revenue Service rule that targeted decentralized finance (DeFi) operations. The president is expected to sign the resolution, though he hasn’t announced a schedule to do so.

Crypto exchange Kraken has registered as a restricted dealer in Canada, allowing the exchange to continue offering crypto trading services to Canadian users under the country’s evolving regulatory framework.

The registration, announced on Tuesday, comes after a multi-year process that required exchanges to meet higher standards for investor protection and governance. Kraken said it worked closely with Canadian regulators during this pre-registration phase, upgrading its compliance systems and internal controls to meet expectations set by the Ontario Securities Commission (OSC).

To lead its Canadian expansion, Kraken named Cynthia Del Pozo as general manager for North America. Del Pozo, a fintech and operations veteran, will oversee strategy, regulatory engagement and business development across the region.

“Canada is at a turning point for crypto adoption,” said Del Pozo in a statement, pointing to growing interest from both retail and institutional investors. A recent survey cited by Kraken found that 30% of Canadian investors currently hold crypto assets.

Kraken also announced it will offer free Interac e-Transfer deposits for Canadian users, a move aimed at reducing friction for newcomers to the platform. The exchange claims it doubled its team and user base in Canada over the last two years and now manages over $2 billion CAD in client assets.

Mayur Gupta, Kraken’s chief marketing officer and general manager of growth, will be speaking at CoinDesk’s Consensus 2025 in Toronto on May 14-15.
