Tom Lee says ‘crypto spring’ started as Bitmine buys $238 million in ether

0

Bitmine (BMNR), the largest Ethereum treasury firm, bought 101,745 ether (ETH) last week as Chairman Thomas Lee said a new “crypto spring” is underway, even as market sentiment remains subdued.

The purchase lifted the firm’s holdings to over 5.18 million ETH, roughly 4.29% of the token’s outstanding supply, according to a Monday update.

Bitmine’s total crypto and cash holdings stand at $13.1 billion. In addition to its ETH position, the firm holds 200 bitcoin , $700 million in cash and equity stakes including investments in Beast Industries and Eightco Holdings.

The latest buy, worth roughly $238 million at current ETH prices, has extended a run of elevated weekly purchases as the firm doubles down accumulating ETH at scale.

Crypto spring builds as CLARITY Act moves forward

That bet is anchored by the firm’s view that crypto markets are climbing out from the past months’ “mini-winter,” as Lee pointed to improving market conditions and positive signs of U.S digital asset regulation, known as the CLARITY Act, moving forward.

“The U.S. Senate released the CLARITY Act compromise text, and while it bans stablecoin yield on reserves, activity-based ‘rewards’ can be offered, in an attempt to balance the needs to protect existing depository institutions (aka traditional banks),” he said in a statement. “This compromise is largely acceptable to us, and we hope to see this bill passed in 2026.” Polymarket’s prediction market traders assigned more than a 60% chance of passage this year, he added.

“Crypto Spring, in our view, has commenced and like past cycles, investor sentiment and conviction are muted and bearish even as crypto prices strengthen,” Lee said.

Lee said Ethereum is benefiting from two long-term trends: the shift of financial assets onto blockchain rails known as tokenization and the rise of artificial intelligence (AI) tools that, in his view, will seek neutral, public networks for payments and verification.

He added that ETH is increasingly viewed as both a store of value and a medium of exchange, citing its outperformance against equities since the start of the Iran conflict.

BitMine has also expanded its staking operations, pledging over 4.36 million ETH — more than 84% of its holdings — to generate yield, earning about $297 million in annualized revenue. Its MAVAN staking platform is designed to support both internal operations and outside institutional demand. Lee will be speaking at CoinDesk’s Consensus Miami this week.

SEC Delays Review of Prediction Market ETFs: Reuters

The US Securities and Exchange Commission has delayed the expected launch of the first exchange-traded funds (ETFs) linked to prediction markets after requesting more information about their structure and disclosures, Reuters reported Monday.

The delay affects more than two dozen proposed ETFs from Roundhill Investments, GraniteShares and Bitwise, according to Reuters, citing people familiar with the matter. The issuers filed for the products in February, and launches had been expected this week after a 75-day review period.

The proposed funds would give investors exposure to event contracts tied to binary outcomes, including elections, economic data and market prices, without requiring them to trade directly on prediction market venues such as Kalshi.

The delay marks another development in the US approach to regulating prediction markets, which have attracted scrutiny over insider trading, ethics and market manipulation concerns.

“Delay is likely temporary”

According to the sources cited by Reuters, the delay is likely temporary, suggesting that progress with the filings could resume once the SEC receives and reviews additional details from issuers on product structure and disclosures.

According to Bloomberg ETF analyst Eric Balchunas, the ETFs were expected to launch on Thursday. His colleague James Seyffart last week said Roundhill’s filing had an effective date of May 5, with the first prediction market ETFs linked to event-contract outcomes such as whether Democrats or Republicans control the House or Senate.

How prediction market ETFs would work

Prediction market ETFs are designed to give investors exposure to binary event contracts without requiring them to trade on specialized prediction markets platforms.

Specific features differ across more than 20 of the proposed ETFs, but the products generally use derivatives to track the odds of binary “yes” or “no” outcomes in underlying contracts traded on CFTC-regulated platforms such as Kalshi. These contracts settle at $1 if an event occurs and $0 if it does not.

Roundhill previously highlighted significant risks associated with the proposed ETFs in its February filings, stating that investments in event contracts involve “unique risks that differ from those associated with traditional futures, options or securities.”

The company said such investments could result in significant losses, valuation uncertainty and deviations from the fund’s investment objective.

It also pointed to potential settlement issues tied to how event outcomes are interpreted, including errors, ambiguities or disputes over the definition of the underlying event, the data sources used or the timing of determination.

Strategy (MSTR) Pauses Bitcoin Buys Ahead Of Earnings

0

Strategy halted its bitcoin buying streak days before earnings, a pause that underscores how much the company now revolves around capital markets rather than software.

Chairman Michael Saylor said Sunday the firm would skip purchases this week and resume next week, marking only the second break this year in what has become a steady accumulation program.

The timing places the decision ahead of Tuesday’s first-quarter report, where analysts expect revenue growth alongside another loss tied to bitcoin accounting and financing costs. Estimates point to revenue near $125 million, up from $111.1 million a year earlier, with a projected per-share loss that varies widely across forecasts.

Strategy holds about 818,334 bitcoin, or close to 3.9% of total supply, reinforcing its position as the largest public bitcoin treasury. Its most recent buy added 3,273 BTC at an average price near $77,900. 

Bitcoin traded around $80,000 in early Monday hours, extending a rebound that has lifted sentiment across crypto markets. 

Because of this price jump, Strategy’s stock was up 3% in early market trading. Over the last two days, MSTR is up over 10%. 

The bitcoin purchase pause itself may reflect standard pre-earnings caution, yet it lands as investors focus less on operating performance and more on the structure funding Strategy’s accumulation.

The company has shifted from a software firm with a bitcoin position into a financing vehicle built to convert market demand into bitcoin exposure. That model relies on continuous access to capital through common stock issuance and preferred shares, including its high-yield STRC instrument.

STRC is Strategy’s new bitcoin driver

STRC, which targets a $100 trading level while offering a variable dividend near 11.5% annualized, has drawn scrutiny from analysts who see asymmetry in its design. Holders receive income tied to Strategy’s balance sheet, yet remain exposed to downside if bitcoin prices fall or if demand for the shares weakens.

The stock pop also comes on the heels of fresh enthusiasm generated by Saylor’s keynote at the Bitcoin 2026 conference in Las Vegas last week.

Rather than focusing on Bitcoin price targets or more Bitcoin purchases, Saylor’s pitch centered on STRC — Strategy’s Bitcoin-backed preferred stock — and a sweeping thesis that digital credit is poised to cannibalize trillions of dollars in the legacy credit market.

“The world’s $300 trillion credit market is a much bigger opportunity than the world’s roughly $2 trillion Bitcoin market, and Strategy has built the first product to bridge the two,” Saylor argued during the keynote.

STRC, which pays an 11.5% monthly variable dividend and trades on Nasdaq, has grown to approximately $8.5 billion in notional value in under nine months — larger, Saylor claimed, than the entire existing universe of monthly-paying preferred securities combined. 

“This is going viral,” he told the audience.

BlackRock’s iShares Preferred & Income Securities ETF has already taken a roughly $210 million position in STRC.

Saylor said STRC has financed the acquisition of approximately 77,000 BTC year-to-date in 2026, roughly ten times the net inflow of all U.S. spot Bitcoin ETFs combined over the same period. 

Recent buying patterns show how quickly Strategy can scale. Ahead of April’s dividend cycle, Strategy deployed more than $3 billion into bitcoin, with purchases concentrated into a handful of sessions exceeding $400 million each.

Trump-affiliated World Liberty sues Justin Sun for ‘defamation’ after Tron creator’s lawsuit

0

World Liberty Financial, the cryptocurrency company affiliated with U.S. President Donald Trump and his family, filed a defamation lawsuit against Tron creator Justin Sun in a Florida state court Monday, alleging “gross misconduct” from Sun over WLFI tokens he bought.

The lawsuit comes on the heels of Sun’s own lawsuit against World Liberty, which was filed in a federal California court, alleging World Liberty had unfairly frozen his ability to transfer his WLFI tokens. In Monday’s suit, World Liberty alleged that Sun-related entities bought WLFI tokens for other investors through straw purchases and may have “engaged in short selling” of the token.

World Liberty froze Sun’s WLFI tokens “to protect” itself “and the broader community as a result, the lawsuit said, adding that Sun’s tweets complaining about his tokens being frozen contain false or defamatory information.

Sun allegedly hired influencers and used bots to “amplify his lies,” World Liberty claimed, and as a result the company said it had “lost specific business opportunities.”

Many portions of the lawsuit were redacted, including portions describing Sun’s purchase of the tokens and sections about his alleged misconduct.

This alleged misconduct includes what World Liberty describes as “a large, deliberate, short-selling campaign designed to suppress $WLFI’s price at the moment of its public launch,” which the suit tied to Sun-affiliated wallets moving $300 million to Binance.

“Upon discovering these violations, World Liberty exercised its contractual rights to freeze Sun’s entities’ tokens to prevent further harm to World Liberty and the broader $WLFI community, an ability that Sun knew about well before this action was taken,” the lawsuit said.

One issue Sun knew about prior to his tweets was that World Liberty had the ability to freeze tokens, the suit said throughout the filing.

“Not only was Sun aware of the agreements’ terms, but Sun also knew through his personal experience that the defamatory statements were false because he (and the public) knew that World Liberty had the power to restrict the transferability of tokens,” the suit said.

The suit alleged defamation and calls for damages, expenses and retraction of Sun’s statements.

Kraken’s parent company Payward alleges $25 million crypto custody fraud in lawsuit against Etana and firm’s CEO

0

Payward, the parent company of crypto exchange Kraken, has accused former custody partner Etana and its CEO, Dion Brandon Russell, of misappropriating more than $25 million in client funds, according to a second amended complaint filed in the U.S. District Court in Colorado on Monday.

The crypto exchange alleges that Etana Custody, which is going through Chapter 11 bankruptcy, operated a “Ponzi-like” scheme in which custodial assets were commingled, spent on operating expenses and risky investments, and falsely reported as intact to clients.

The Wyoming-based firm said it entrusted Etana with hundreds of millions of dollars over several years as part of a fiat on-ramp partnership. But when it sought to withdraw roughly $25 million in reserve funds in April 2025, Kraken claims Etana stalled with what it alleges as fabricated reconciliation issues and misleading explanations.

According to the complaint, Etana lacked the funds to meet the withdrawal request and instead relied on new deposits to cover shortfalls.

“Kraken has millions of users and hundreds of billions of dollars in quarterly transaction volume. We did not get here by rolling over. If you take our money or deceive our customers, then know this: we will find you, we will sue you, and we will not stop until justice has been served,” Matt Turetzky, head of litigation at Kraken, said in emailed comments.

Etana didn’t respond to a request for comment by publication time.

Counterparty risk, the danger that a firm holding or facilitating users’ assets can’t return them, has become a defining issue in crypto markets, where users often rely on exchanges, lenders and custodians to safeguard funds.

Unlike traditional finance, where segregation, insurance and oversight are more standardized, crypto platforms have historically operated with looser controls, making it harder to verify whether assets are fully backed.

High-profile failures from FTX to smaller custodians have shown how quickly trust can evaporate when that assumption breaks. Cases like Kraken’s dispute with Etana underscore the same core concern, whether customer funds are truly ring-fenced or exposed to operational and liquidity risks behind the scenes.

Kraken is a U.S.-based crypto exchange operated by Payward Inc., offering spot and derivatives trading alongside custody and staking services. Founded in 2011, the platform serves both retail and institutional clients globally, supporting trading in assets like bitcoin and ether (ETH), as well as fiat on- and off-ramps. It is known for emphasizing security and regulatory compliance across multiple jurisdictions.

Etana is a crypto-focused custody firm that provided fiat on- and off-ramp services and held customer assets on behalf of exchanges like Kraken.

The lawsuit outlines several alleged instances of misuse. In one, Etana purportedly deployed at least $16 million of Kraken-related funds into promissory notes issued by Seabury Trade Capital, which later defaulted. Kraken claims those funds were never returned and may have been diverted to cover company expenses.

In another, Etana is accused of using customer assets to finance a foreign-exchange hedging strategy while retaining any investment income for itself.

Throughout this period, Kraken alleges that Etana continued issuing account statements and dashboard updates that showed customer balances as secure and fully accounted for, despite internal shortfalls.

Regulatory pressure mounted in 2025, when Colorado authorities issued a cease-and-desist order and increased capital requirements. Etana ultimately entered liquidation proceedings in November 2025 and is now under the control of a court-appointed receiver.

Kraken is seeking at least $25 million in damages, along with potential treble damages under civil theft claims, plus injunctive relief and attorneys’ fees.

The complaint also targets Russell personally, alleging he exercised near-total control over Etana’s operations and directed the misuse and concealment of funds.

The custodian isn’t the only crypto firm to run into liquidity trouble in recent months. Institutional lender Blockfills filed for bankruptcy in March after halting withdrawals, reporting roughly $75 million in losses and facing a lawsuit alleging misuse of customer funds.

Kraken parent Payward closes $550 million Bitnomial deal, securing full CFTC derivatives stack

0

Payward, the parent company of crypto exchange Kraken, has completed its acquisition of Bitnomial, giving the firm a full U.S. derivatives stack regulated by the Commodity Futures Trading Commission (CFTC).

The deal gives Payward control of Bitnomial’s futures broker, exchange and clearinghouse licenses. That structure allows Payward to offer regulated crypto derivatives in the U.S. without relying on a patchwork of third-party venues.

The transaction values Payward’s equity at $20 billion. It follows the firm’s $1.5 billion acquisition of retail futures platform NinjaTrader in 2025, the two deals together forming the backbone of its U.S. derivatives push.

Payward said it plans to start with spot margin on Kraken and NinjaTrader. Perpetual futures, contracts without a set expiry, and options are expected to follow.

The acquisition also gives Payward a business-to-business path. Banks, fintech firms, and brokerages could connect to regulated U.S. derivatives products through a single integration with Payward Services, the company added.

Bitnomial was founded in 2014 and spent more than a decade building its CFTC licenses. Payward is paying up to $550 million in cash and stock for the company, according to the provided briefing.

The deal comes as U.S. crypto firms race to bring derivatives onshore under CFTC rules. Coinbase has already launched perpetual-style futures in the U.S., while other trading firms are exploring similar products.

The crypto futures and options market has become the dominant layer of digital asset trading, dwarfing spot activity in both volume and leverage. In the past 24 hours alone, crypto futures have generated around $200 billion in trading volume, roughly double the activity in spot markets. A significant portion of this market, particularly options, is concentrated on unregulated offshore venues, limiting direct access for U.S.-based traders.

Bitcoin stalls near $80,000. Stocks and ETF inflows still point to a breakout: Crypto Daily

0

Bitcoin has pulled back to $79,000 after briefly topping $80,000 during the Asian hours. As of writing, the leading cryptocurrency by market value was still up 0.4% on a 24-hour basis.

The CoinDesk 20 Index was up 0.4% alongside a nearly 1% rise in ether (ETH) and marginal gains in XRP (XRP) and solana (SOL).

According to analysts at Marex, the level map matters more right now than the narrative.

“80k is the psychological barrier. A clean break and hold above it turns this into a momentum trade with room to extend. A rejection and fade keeps us in the same range logic and invites profit taking back toward the mid 70s,” they said in an email.

“This is exactly where traders watch whether spot demand keeps lifting offers or whether the move is mostly positioning,” they added.

The probability of a clean break above $80,000 remains high, thanks to the risk-on sentiment in global markets and strong market flows.

“The driver stack is straightforward. Equities are firmer on AI and megacap earnings, and crypto is riding that risk-on impulse. At the same time, institutional demand is clearly back in the mix,” Marex analysts said.

“Strong ETF inflows into the end of last week tell you real money is buying the breakout attempt rather than fading it,” they added. Marex Crypto is an institutional-focused division of Marex Group plc, a diversified financial services firm.

The 11 U.S.-listed spot exchange-traded funds (ETFs) pulled in more than $600 million on Friday, extending a run of institutional demand that has totaled $3.29 billion over the past two months, according to data source SoSoValue.

“Spot ETF flows also remain supportive, with roughly $163m in net inflows last week. While there were notable outflows from April 27 to 29, likely tied to month-end rebalancing and some basis trade adjustments, Friday’s approximately $630m inflow more than offset those earlier outflows,” the market insights team at Singapore-based QCP Capital, one of the largest digital asset trading firms in Asia, said.

Even with the supportive backdrop, analysts noted a few key risks that could pose headwinds.

Firstly, the risk-on rally could face renewed pressure if tensions between the U.S. and Iran flare up again. The two sides have been engaged in peace talks for weeks without a breakthrough, while energy markets remain sensitive to any disruption linked to the Strait of Hormuz, a key global shipping route for crude oil.

Amid this, U.S. President Donald Trump has threatened to impose tariffs on countries that purchase Iranian oil.

“Global markets are entering a more fragmented phase with trade tensions intensifying. The United States has warned China of 100% tariffs if it continues purchasing Iranian oil. China has responded with defiance. At the same time, President Trump has raised tariffs on EU vehicles to 25%, adding pressure to transatlantic relations,” Timothy Misir, head of research at BRN, said.

Second, persistent security risks in decentralized finance (DeFi) threaten widespread adoption.

For now, though, the setup is straightforward: equities are strong, ETF inflows are rising, and bitcoin is riding both. Stay alert!

What’s trending

Today’s signal

The chart shows bitcoin’s weekly price swings in candlestick format.

Early today, BTC tested the resistance at $80,619. That’s the level where the November sell-off ran out of steam, paving the way for a bounce.

A decisive break above this level would strengthen the case that the recent rebound is part of a broader uptrend, potentially opening doors to $85,000. However, failure to break through could see the rally stall, with the market at risk of another round of selling pressure.

BTC, therefore, is at a make or break level.

Capital B Raises $1.2M from Adam Back to Fuel Bitcoin Treasury Strategy

0

Capital B raised 1.1 million euros ($1.28 million) through a warrant issuance subscribed by Blockstream CEO Adam Back, extending the cryptographer’s backing of the French-listed Bitcoin treasury company.

Back subscribed to 10 million subscription warrants at $0.13 each, according to a Monday announcement from Capital B. Each warrant gives Back the right to buy one new share of future company stock at the exercise price of $0.98, corresponding to the company’s market net asset value (mNAV) of 1.1 per share, the company said.

The deal would increase Back’s exposure to Capital B, where he is already one of the company’s largest strategic investors. Back now holds over 39.5 million shares or 9.97% of Plan B’s shares on a fully diluted basis. Back is best known as the inventor of Hashcash, the proof-of-work system cited in the Bitcoin white paper.

The raise comes as some Bitcoin treasury companies continue seeking capital for accumulation strategies, while others are using derivatives or asset sales to manage balance sheet risk during Bitcoin’s downturn. Capital B and the United Kingdom-based Connecting Excellence Group (XCE) were the only Bitcoin treasury companies to raise capital in Europe over the past month.

XCE’s $794,000 capital raise on April 23 was also backed by Adam Back.

Capital B shares rise 6% after capital raise announcement

Capital B’s said the new capital will be used to “accelerate” its Bitcoin treasury strategy, which was perceived as a positive signal from shareholders.

Capital B’s stock price rose by over 6.5% on Monday, but is still down over 16% since the beginning of 2026, data from Yahoo! Finance shows.

Capital B is the 25th largest Bitcoin treasury company, holding 2,943 BTC currently worth about $234 million, according to Bitcointreasuries.net data.

Other Bitcoin treasury companies are reducing the balance sheet risk associated with Bitcoin’s downturn.

On April 24, Nasdaq-listed Bitcoin treasury company Nakamoto announced an actively managed Bitcoin derivatives program seeking to generate recurring income from volatility and hedge part of its corporate BTC holdings against downside exposure.

Nakamoto is the 20th-largest Bitcoin treasury firm and the largest to disclose selling part of its holdings earlier this year. The company announced a sale of 284 Bitcoin (worth about $20 million at the time) in a March 30 filing with the US Securities and Exchange Commission. 

A month earlier, in February, Bitcoin treasury company Genius Group said it liquidated its entire treasury holdings of 84 BTC for about $5.7 million, which it used in repaying an $8.5 million debt obligation, according to an SEC filing.

Law Firm Files Restraining Notice for Kelp Exploit ETH

0

A US law firm has filed a restraining notice to block the transfer of frozen Ether from the Kelp exploit, arguing that its clients are owed over $877 million in compensation and damages by North Korea. 

Charlie Gerstein, a lawyer for US law firm Gerstein Harrow LLP, said in a post on the Arbitrum DAO forum on Friday that a New York district court signed off on a restraining notice and three writs of execution preventing the DAO from moving the Ether under threat of contempt of court.

The law firm argued that its clients, who were not affected by the Kelp exploit, won default judgments against North Korea in three separate US court cases in 2010, 2015 and 2016 and are owed a collective $877 million in compensatory and punitive damages, plus interest. It also argued that its clients have a claim to DPRK property. Gerstein said in the restraining notice that the stolen Ether is “property” in which the DPRK has a stake because the hacker group is affiliated with the country.

The freeze could mean those affected by the Kelp exploit would need to wait longer to see their funds recovered. This isn’t the first time the firm has attempted to claim stolen cryptocurrency.

Kelp DAO suffered a $292 million hack on April 18, which is believed to have been carried out by TraderTraitor, a subgroup of North Korea’s state-backed hacking unit, Lazarus Group. 

Days later, Arbitrum Security Council took emergency action to freeze 30,766 Ether (ETH), worth over $73 million, held in a wallet linked to the Kelp exploit.

Funds were proposed for Kelp victims

Aave Labs proposed on April 25 that the Arbitrum DAO unfreeze the $73 million in Ether tied to the Kelp DAO attack and direct those funds to “DeFi United,” a fund aimed at restoring rsETH and compensating its holders.

An Arbitrum DAO member under the handle Zeptimus said that if the law firm’s action is successful, the DPRK debt will not be transferred to the Kelp DAO victims.

“Your clients’ losses are real and the DPRK should answer for them. But the remedy the restraining notice asks for, blocking the return of stolen funds to their actual owners shifts the cost of the DPRK’s debt onto a different set of victims who were themselves robbed. That compounds the original harm; it doesn’t redress it,” they said.

Gerstein Harrow filed similar claims before

Gerstein Harrow has filed similar cases in the past, arguing its clients have a claim to funds stolen by the DPRK and frozen by crypto firms. In February, the firm filed a claim against funds frozen by Tether that were stolen in the 2023 Heco Bridge hack.

It has also filed class-action suits against multiple DAOs. At the same time, onchain sleuth ZachXBT accused the law firm of using his research in court documents to stake a claim on funds from the $1.5 billion Bybit hack.

North Korea-affiliated actors have been accused of stealing at least $578 million across major incidents throughout April and have been linked to many of the industry’s largest hacks, including the Bybit exploit.
