Crypto asset manager Grayscale Investments has dropped plans for exchange-traded funds tied to Cardano’s ADA, Polkadot’s DOT and Hedera’s HBAR, withdrawing three registration statements from the U.S. Securities and Exchange Commission (SEC) late Friday.

Through three separate requests with the regulator, Grayscale told the SEC it “does not intend to proceed with the planned distribution” of the shares of each trust.

The withdrawals were initiated by Grayscale and weren’t SEC rejections.

Grayscale’s initial Cardano ETF proposal came in February 2025, and its Polkadot filing later that month. Grayscale filed the corresponding ADA and DOT registration statements on Aug. 29, followed by its HBAR registration on Sept. 9.

The proposed funds were designed as passive vehicles that would track the value of their respective tokens after fees and expenses. Grayscale said it had not sold securities or distributed preliminary prospectuses under the registrations.

All three tokens have been losing value over the last few months. Year-to-date, ADA is down more than 41%, while DOT lost 54% of its value and Hedera’s HBAR lost 35%.

Since late February 2025, when the filings came in, performance has been worse. ADA endured a 70% drawdown, while DOT saw an 80% downward move. HBAR also dropped more than 70%.

Bitmine Immersion (BMNR), the largest Ethereum treasury firm, bought another 7,391 ether ETH$1,892.21 last week.

The purchase, worth roughly $14.2 million at ether’s price as of writing of $1,915, lifted the company’s holdings to over 5.8 million ETH, or about 4.8% of Ethereum’s total supply.

The latest haul, which extends Bitmine’s ETH buying streak to 58 weeks, was the smallest weekly purchase through the year and remains a fraction of the 100,000-plus weekly acquisitions Bitmine made earlier this year.

Thomas Lee, chairman of Bitmine, noted earlier this year that the firm would slow the pace of crypto accumulation as it gets closer to its goal of owning 5% of ether’s supply.

Instead, the company has shifted towards buying back shares. It repurchased another 3 million shares last week, which would have cost roughly $50 million to $58 million based on the stock’s trading range during the period. Since July, the firm has bought back 19.1 million of its own shares.

Bitmine also holds 209 BTC, $104 million in cash and marketable securities and stakes in Beast Industries and Eightco Holdings.

Bitmine shares traded flat neat $18.80 in pre-market trading.

Clarity delay

Lee focused on the macro backdrop despite another setback for U.S. crypto legislation, with the CLARITY Act failing to secure a Senate vote before the August recess.

The extra yield exists only if traders actually swap through those pools, which means Jupiter not only runs Solana’s largest swap router, the software most wallets and apps use to find the best price across venues, but it also owns pools that need that flow to arrive.

The company told CoinDesk the router does not favor its own vaults and sends swaps wherever the price is best.

The risk of pairing assets falls unevenly, however. Jupiter said margin is valued using primary market oracles, or data providers, so a temporary price wobble on an exchange does not trigger anything, and a position liquidates as normal once its loan-to-value ratio passes the threshold.

A genuine depeg is different. On the debt side the borrower is protected — someone borrowing $100 split between USDC and USDT would see the pool rebalance into whichever asset held its value and still owe $100. On the collateral side there is no such protection, and a supplier carries the loss on both assets if either breaks.

That is why the design is confined to correlated pairs, stablecoins against each other and SOL against its staked versions, rather than volatile assets.

“There’s been a wall between the two primary ways people earn APY onchain, lending and LPing,” said Kash Dhanda, Jupiter’s chief operating officer, referring to lending and supplying liquidity to exchanges.

Strategy, the publicly traded firm with the largest corporate Bitcoin treasury, has again converted part of its BTC holdings into cash to support buybacks of its STRC preferred stock. In its latest SEC filing, the company reported a second consecutive week of Bitcoin sales used to fund repurchases of STRC shares.

According to a Monday 8-K filing with the US Securities and Exchange Commission (SEC), Strategy sold 1,690 Bitcoin for $108.6 million between Aug. 3 and Aug. 9. The proceeds were used to buy back 1.15 million shares of its STRC preferred stock for the same $108.6 million total.

Key takeaways

• Strategy sold 1,690 BTC for $108.6 million (Aug. 3–Aug. 9) to repurchase STRC preferred shares.
• This was the company’s fourth disclosed Bitcoin sale of 2026, bringing 2026 total BTC sales to 6,948.
• Strategy still holds 840,447 BTC with an aggregate purchase price of $63.36 billion, implying ongoing long-term exposure.
• The filing shows remaining repurchase capacity under both the preferred stock and common-stock buyback programs.
• Alongside STRC buybacks, Strategy continued building a US dollar reserve, reporting $4.65 billion as of Sunday.

Bitcoin sales tied directly to STRC buybacks

Strategy’s latest filing reinforces the company’s funding approach: using periodic Bitcoin liquidations to finance preferred stock repurchases. STRC is a variable-rate preferred stock structured to pay monthly dividends, and Strategy’s buybacks appear designed to manage capital structure while continuing dividend-related obligations.

On this occasion, the company reported an average net sale price of $64,262 per Bitcoin for the 1,690 BTC it sold. For comparison, Strategy’s broader Bitcoin cost basis is higher: the company cited an average purchase price of $75,385 per BTC for total holdings, including fees and expenses.

Strategy also previously disclosed a similar sequence. Earlier coverage noted that Strategy sold 1,638 BTC for $104.73 million between July 27 and Aug. 2, and used those proceeds to fund STRC repurchases as well. The current week’s sale follows that pattern closely—suggesting the company is maintaining an active, repeatable mechanism rather than relying on one-off treasury adjustments.

How much BTC Strategy has sold in 2026

While the latest transaction adds another step to Strategy’s 2026 funding routine, it does not represent a major shift away from holding BTC. The filing states the trade marked the company’s fourth disclosed Bitcoin sale of the year, bringing total 2026 BTC sales to 6,948 BTC.

After the latest sale, Strategy still holds 840,447 Bitcoin purchased for an aggregate $63.36 billion. That large remaining position matters for investors because Strategy’s balance sheet exposure to Bitcoin remains the dominant driver of its treasury value, even as the company periodically monetizes BTC to meet financial objectives.

From a market perspective, these disclosures also keep the question of “how much BTC is converted” in focus. If Strategy’s buyback-linked sales continue on a regular cadence, traders may increasingly weigh whether those conversions pressure sentiment around BTC liquidity at specific intervals—even if the firm’s long-term exposure remains intact.

Repurchase capacity and the dollar reserve build

Beyond the immediate buyback, the 8-K includes additional numbers that help map out how Strategy plans to fund and sustain the preferred stock program. The filing says Strategy has $785.2 million remaining under its digital credit securities repurchase program, which covers the preferred stock. It also reports another $1 billion available under its Class A common-stock repurchase program.

Strategy simultaneously continued building its US dollar reserves. The company reported a $4.65 billion balance as of Sunday, up from roughly $4 billion in the previous weekly update. In the filing, Strategy said $650 million of $653.1 million in net proceeds from recent MSTR stock sales went toward the reserve.

The reported cash number also includes expected proceeds from at-the-market (ATM) sales that had not yet settled at the time of the update. Taken together, the reserve build is relevant because it may reduce the need for frequent immediate BTC liquidations under certain market conditions—while still leaving BTC as the core long-duration holding.

STRC share momentum alongside buybacks

Strategy’s STRC buybacks come at a moment when the preferred stock has shown strength. The article cited that STRC shares rallied during Strategy’s recent repurchases, reclaiming $90 on Aug. 3 after rebounding 24% from their June lows.

In premarket trading Monday, STRC was up 0.46% to $95.45, after closing Friday at $95. According to Yahoo Finance, Strategy’s MSTR shares were also slightly higher, up 0.25% to $100.26 at the time of the report.

While price moves in any single session can’t be attributed solely to buybacks, the sequence is still notable: repurchases funded by BTC sales are arriving while market participants appear willing to bid up STRC from earlier weakness. For investors, the practical takeaway is that Strategy’s corporate actions are being tested in real time by equity market liquidity, particularly around preferred stock where dividends and variable-rate mechanics can influence demand.

Looking ahead, readers should watch two things: whether Strategy continues the pace of BTC-to-STRC conversions disclosed in its SEC filings, and how the firm’s remaining repurchase capacity and US dollar reserve evolve week to week. Any change in the cadence—or in the average net sale price compared with its cost basis—could affect how investors interpret the trade-off between maintaining BTC exposure and supporting the company’s preferred stock funding engine.

Quantum Fintech Group founder Harry Chun Tak Yeh was found dead in Paraguay after falling from his luxury 30th-floor apartment last week. 

Local media reports that Yeh fell from his apartment in the early hours of the morning, either on a Tuesday or Friday, before his naked body was found covered by a black plastic bag.

Police discovered his apartment ransacked with the door wide open, and nobody else present. 

Yeh’s 29-year-old partner, Isadora de Proenca Braganholo Carvalho, says she was unaware of what happened. The Brazilian national was staying in Yeh’s other apartment on the 27th floor.

Police are currently investigating whether or not Yeh’s death was an accident, suicide, or a potential murder. 

Yeh made his fortune investing in BTC in 2013 when it was worth roughly $60. He then went on to found crypto hedge fund Quantum Fintech Group in 2020 and claimed to manage over $2 billion worth of funds.

One crypto developer, who goes by “@0xz80 on X,” shared some “stories” about Yeh. 

Yeh supposedly gathered a group of Fantom layer-1 developers and 500 Dubai-based escorts together for an event, and joked that “Us 200 crypto nerds [had] no idea how to talk to them.”

@0xz80 also claimed that Yeh rented out an entire E11even, a famous nightclub brand and gave his developers crates full of cash.

In addition to these displays of wealth, @0xz80 added that Yeh “made it to the top of some of the sketchiest corners of crypto,” and that he was “one of the sketchiest people I’ve ever met in my life.”

XRP struggles amid weaker ETF inflows, while UE Crypto expands access to cloud mining with free services and mobile management for major crypto assets.

Recent data shows that the upward momentum of spot XRP ETFs continues to weaken, while XRP price performance remains sluggish, significantly underperforming major digital assets such as Bitcoin and Ethereum.

Affected by factors including slowing ETF inflows and declining trading activity of Ripple’s stablecoin RLUSD, XRP continues to face price pressure. It is currently hovering around $1.0424, only about 3.5% above its yearly low of $1.007, as short-term market caution continues to increase.

Why is cloud mining becoming increasingly popular?

Traditional cryptocurrency mining often requires significant hardware investment, professional mining facilities, and 24/7 dedicated maintenance. It not only has high entry barriers and substantial upfront costs, but also involves challenges such as rapid equipment upgrades, high electricity consumption, and frequent equipment failures.

The emergence of cloud mining has fundamentally changed this situation. There is no need to purchase mining machines, deploy equipment, or handle professional maintenance. Users simply select a suitable computing power plan online and can remotely access large-scale computing resources. With one-click participation, automated operation, and earnings settlement, cloud mining enables users to pursue long-term passive income with a low barrier to entry and is becoming an increasingly popular choice among digital asset investors.

UE Crypto launches a new free cloud mining service

UE Crypto — a global leading cloud computing power service platform headquartered in the United Kingdom — has officially launched a free cloud mining experience for users worldwide. The platform supports major digital assets including BTC, XRP, DOGE, LTC, and ETH.
