South Korea’s Upbit recorded 1.15 trillion won, roughly $830 million, in trading volume within a single hour on Saturday, with XRP and TRUMP dominating the surge.

The spike extends a rebound that began the previous day, when Upbit’s daily volume already jumped 273%.

What Drove Upbit’s Record Hourly Volume

XRP led the charge by a wide margin. The token accounted for 32.20% of Upbit’s 24-hour trading volume, ranking first among all traded assets, according to Upbit Datalab.

TRUMP ranked second on the exchange, contributing 10.93% of total volume. USDT followed in third place with 8.39%, while Ethereum and Bitcoin rounded out the top five at 5.44% and 5.40%, respectively.

Upbit’s total 24-hour trading volume reached approximately $3.81 billion, while rival exchanges Bithumb and Coinone recorded $1.954 billion and $172 million, respectively.

Saturday’s spike was not an isolated event. On August 21, Upbit’s daily volume had already jumped 273% to roughly $1.84 billion, marking the exchange’s highest daily volume since mid-March.

XRP topped that session too, contributing $418.9 million and ranking ahead of Bitcoin, USDT, and ETH. Bithumb recorded a similar increase that day, with volume climbing 132.9% to about $934.9 million.

Why the Rebound Follows Months of Weaker Activity

That earlier rebound followed months of weaker trading, as South Korean investors favored domestic equities while the KOSPI climbed to record highs on AI-driven semiconductor demand. Upbit and Bithumb both reported declines in operating revenue of nearly 50% during the first half of 2026.

XRP traded near $1.44 at the time of writing, according to BeInCrypto data, up 2.1% over the past 24 hours despite an intraday flash crash and up nearly 50% over the past week. The token’s rally followed Ripple’s backing of a major XRP Ledger amendment, alongside strong ETF inflows.

That gain remains positive despite a brutal 37% flash crash earlier in the day, which briefly pushed XRP as low as $1.36 before it recovered, liquidating hundreds of millions in leveraged positions along the way.

TRUMP held its gains more cleanly. The token traded near $2.34, up 26% in 24 hours and more than 66% over the past week. Its all-time low of $1.37 came just nine days ago, on August 13.

Speculation around a Robinhood Chain launch has fueled renewed interest in the token, alongside a broader recovery across Solana-based meme assets. Whether this two-day streak marks a lasting rotation back into crypto or another short-lived wave, as seen repeatedly this year, remains an open question for South Korean traders.

US-listed Bitcoin (BTC) and Ethereum (ETH) exchange-traded funds each recorded their largest week since October 2025, drawing a combined $2.6 billion in the seven days ended August 21.

Bitcoin products captured $1.92 billion of that sum. Ethereum funds added $697.18 million, reversing a $391.96 million combined outflow the previous week.

Bitcoin and Ethereum ETFs Hit Biggest Weekly Inflow in 10 Months

According to SoSoValue, Bitcoin funds recorded five consecutive days of net inflows from August 17 to August 21. The run included a $606 million single-day haul on August 20.

Trading activity climbed alongside the money. Weekly volume in BTC funds reached $22.15 billion, roughly triple the prior week’s total.

The week interrupts a long retreat. Cumulative net inflows into Bitcoin ETFs peaked at $62.77 billion in October 2025 and have since fallen to $53.71 billion.

Ethereum funds followed a similar path. Their largest daily intake since October landed on August 20 at $220.77 million. Total assets, however, remain 53% below the August 2025 high.

The annual picture stays negative for both. BTC funds have shed $2.91 billion in 2026 and ETH products $177.93 million, leaving each on track for its first losing year since launch.

Assets Grew 9 Times More Than New Money

The flow figures understate what actually moved. Combined assets across both products rose by about $23 billion last week, compared with $2.6 billion in creations.

Stripping out flows, the implied gain in the underlying holdings reached 22.9% for Bitcoin and 29.2% for Ethereum. Three sessions from August 19 to August 21 produced most of it.

Revaluation, therefore, did the heavy lifting. Bitcoin traded near $77,125 at press time, while Ethereum changed hands at $2,423.

Altcoin Funds Extend the Run

Other major US altcoin spot ETFs also posted net inflows over the same week. XRP (XRP) ETFs led with $39.78 million and set a record for weekly trading volume at $271.74 million.

Solana (SOL) products followed with $28.34 million, marking an eighth consecutive week of inflows. Chainlink (LINK) funds drew $13.35 million, their second-largest week since launching in December. Assets closed at a record $171.59 million.

Hyperliquid (HYPE) products added $3.89 million and also finished at record assets of $360.39 million. Dogecoin (DOGE) funds trailed the group with $654,416.

Coinkite, the company behind Coldcard, has shipped a firmware update that will not generate a new wallet seed until the owner supplies randomness by hand.

That means at least 50 dice rolls, 128 coin flips, or 65 timed key presses, three weeks after a defect in its random number generator opened customer funds to attackers.

Coldcard’s two device lines run separate firmware tracks, so the release carries two numbers, 5.6.1 for the Mk4 and Mk5, and 1.5.1Q for the Q, the larger model with a keyboard and QR scanning.

Boot Check Targets the Defect

Coinkite stated that the input is added on top of device randomness from the STM32 TRNG and both secure elements.

Coldcard was built to draw seed entropy only from its hardware generator, but Coinkite traced the failure to a build and link error that left the setting meant to disable the software path without effect, sending the random-number call to MicroPython’s Yasmarang PRNG, which entered the seed path in March 2021.

Affected seeds carry about 72 bits of entropy instead of the expected 128 bits after 594.5 BTC was swept from 500 addresses on July 30.

Firmware 5.6.1 now verifies at boot that the random-number call reaches the intended hardware path, halting the device if it fails. Coinkite replaced Yasmarang with a SHA-256 Hash_DRBG, specified in NIST SP 800-90A, and seeds it at startup with a full 256-bit digest from both secure elements, which earlier firmware truncated to 32 bits.

Key mashing follows Peter Todd’s push-button RNG design, hashing keypad press timing at CPU-cycle resolution. The first press sets a reference, and each of the 64 gaps that follow is credited with two bits of entropy.

Old Seeds Still Need Migrating

“Installing this update does not make an existing vulnerable seed safe,” Coinkite wrote, directing anyone whose seed may have been generated on affected firmware between 2021 and July 2026 to create a replacement and move their Bitcoin (BTC). Mk2 and Mk3 fall outside this release, and their minimum fixed version stays at 4.2.0.

A compromised USB host could rewrite a staged transaction after the owner approved it, so the signature covered different outputs. The device now rechecks those bytes before signing and stops with a “Transaction modified” warning.

Coinkite’s new Security Status page lists four independent reviews, among them a real-device test that observed eight hardware RNG reads for a 32-byte seed request and a rebuild matching every byte of the signed firmware.

The company noted that the checks are “not a complete audit of every firmware binary.” As CryptoPotato reported, confirmed losses passed $100 million, with Galaxy Research counting 1,596 BTC from roughly 7,300 addresses, and a suspected fourth wave sweeping nearly 449 BTC on August 3.

Bitcoin has staged an aggressive breakout after weeks of compressed price action, pushing through several important resistance levels in a short period. While the move has materially improved the technical picture, BTC is now approaching another major supply area, making the sustainability of the breakout the key question.

Bitcoin Price Analysis: The Daily Chart

On the daily timeframe, Bitcoin has decisively broken above the long-standing descending trendline and the $66K-$67K resistance zone. The breakout was followed by an exceptionally strong expansion, with price also clearing the intermediate $72K-$74K supply area and reaching roughly $79K before pulling back toward $77K.

This represents a notable shift in market structure. The descending trendline had capped BTC throughout the broader correction, so reclaiming it alongside multiple horizontal resistance zones suggests buyers have regained control, at least in the near term.

However, price is now approaching the major $80K-$83K resistance zone. This area previously marked an important swing high and could attract profit-taking following such a rapid advance. A breakout and daily acceptance above $83K would further strengthen the bullish structure and potentially open the way toward the much larger $94K-$98K supply zone.

Conversely, after such a vertical move, a correction would not necessarily invalidate the breakout. The former $72K-$74K resistance zone is now the first major area to monitor as potential support. Holding this region on a pullback would reinforce the idea that the recent move represents a genuine structural reversal rather than a temporary liquidity-driven spike.

BTC/USDT 4-Hour Chart

The 4-hour chart highlights the strength of the breakout more clearly. Bitcoin escaped the converging trendline structure around $64K-$65K and accelerated almost vertically, eventually reaching approximately $79.5K.

Given the speed of the advance, the market is now extended from its breakout point, increasing the probability of short-term consolidation or a corrective retracement. The $72K-$74K zone is the first significant support area, while the Fibonacci levels shown on the chart provide deeper retracement references at roughly $71.1K, $69.1K, $67.7K, and $66.3K.

The $66K-$67K region is particularly important because it combines the former horizontal resistance area with the broader breakout structure. A deeper correction into this region, followed by strong demand, could still preserve the bullish setup.

For now, the immediate obstacle remains the $79.5K high followed by the $81K-$83K supply zone. A period of consolidation beneath this resistance would be relatively constructive, whereas an immediate rejection followed by a loss of $72K could indicate that the market needs a considerably deeper reset before attempting another leg higher.

On-chain Analysis

The Realized Price UTXO Age Bands chart provides additional context for the breakout by showing the average acquisition prices of different groups of Bitcoin holders.

The most relevant development is that BTC’s surge toward $79K has pushed spot price above the realized-price levels of the shorter-term 1-3 month and 3-6 month cohorts, which sit around $64K and $74K, respectively. This means these groups have broadly moved back into unrealized profit, reducing some of the pressure associated with underwater recent buyers.

At the same time, several older cohorts remain positioned considerably above the current market price. The 18-month to 2-year realized price is around $87K, while the 6-12 month and 12-18 month bands are much higher, near $95K and $105K. These levels could become increasingly relevant if the recovery continues, as BTC would begin approaching the cost bases of holders who remain underwater.

Therefore, the on-chain structure has improved alongside the technical breakout, but the recovery is not yet complete. Holding above the roughly $74K cost basis of the 3-6 month cohort would be particularly constructive, while losing it could indicate that the latest surge has moved ahead of underlying holder support.

BounceBit will permanently shut down its Layer 1 blockchain after an attacker moved 286.5 million BB out of nine mainnet accounts. The project will reissue the token as a BEP-20 asset on BNB Chain.

The team said the attacker compromised no private keys, wallets, or hardware devices. The unauthorized transfers came from a protocol-level authorization vulnerability.

Why BounceBit Will Not Restart Its Chain

BounceBit Chain ran on the Evmos stack, which lets smart contracts call protocol-native modules directly. One of those modules handles vesting and lockup accounts.

A funder account should be debited only after it authorizes the transfer. Along the smart-contract path, that binding was bypassed, and a second permission check ran against the wrong account. The attacker could therefore designate any account as the funding source without the holder’s consent.

The attacker ran 14 transactions over 4 hours and 52 minutes on 19 and 20 August, using two accounts and 15 single-use contracts. Block production stopped at height 20,702,857, roughly 42 minutes after the final transfer.

Meanwhile, Evmos itself has been discontinued. BounceBit said moving its fork to a successor codebase would demand a full rebuild, re-audit, and revalidation rather than a routine upgrade.

“Importantly, BounceBit CeDeFi Strategy, Promo Vaults, Prime, and RWA products are not affected,” the post read.

The exploit follows a security incident at MANTRA, which froze its network this week due to a vulnerability in an upstream dependency.

What the Snapshot Means for BB Holders

The team will set the balances from block 20,697,260. None of the BB tokens that moved during the incident exist on the reissued token.

BB transfers made during the 5-hour-34-minute window will be reversed. Buyers will have those purchases undone, while sellers will receive the BB they sent back. Staked and unbonding balances count toward the snapshot.

BounceBit plans to credit reissued altcoins automatically to matching BNB Chain addresses. There is no claim site.

“We know this is disruptive, nothing is expiring and nothing is being rushed,” the team said.

BB traded near $0.0111 on Saturday, up 16% over 24 hours, per BeInCrypto Markets data. The token hit a record low of $0.0079 on August 20, about 31% below its level before the attack.

That leaves BB roughly where it started the week. The stolen supply amounts to about 13.6% of the 2.1 billion maximum, worth nearly $3.2 million at current prices.

EX DeFi attracts XRP investors seeking diversified income via cloud mining as ETF inflows revive institutional interest.

Advertisement

Summary

• US spot XRP ETF inflows hit $1.552B, with $18.38M added Aug. 21 as institutional demand rebounds.
• XRP ETFs reached $1.552B in total inflows; Bitwise captured $16.89M of Aug. 21’s $18.38M daily inflow.
• Institutional XRP demand is rising, as US spot ETFs logged $1.552B in cumulative inflows by Aug. 21.

Cumulative net inflows into US spot XRP ETF continue to rise; the latest data shows that as of August 21, the total net inflow reached approximately $1.552 billion. Meanwhile, single-day net inflows for XRP ETFs stood at around $18.38 million — with the Bitwise XRP ETF alone attracting about $16.89 million — signaling a resurgence of institutional interest in XRP.

The continued inflow of funds into XRP ETF and the subsequent rebound in XRP’s price further reflect that institutional investors are still increasing their XRP holdings through regulated financial products. While retail investors must still contend with market volatility and price uncertainty, the recent return of capital to the ETF market provides a measure of support for XRP future performance.

As the regulatory environment and financing conditions improve, more investors are considering a practical question: beyond simply waiting for the price of XRP to rise, are there more efficient and flexible ways to participate in its long-term value growth?

Against this backdrop, savvy investors are turning their attention to the EX DeFi cloud mining platform. They aim to explore diversified revenue streams — moving beyond reliance solely on price appreciation—while maintaining a long-term interest in XRP’s development.

What signal do the continued XRP ETF inflows send?

Since their launch, US spot XRP ETFs have seen cumulative net inflows surpass $1.5 billion, with new capital continuing to flow in recently. The latest data indicates that the total net inflow has risen further to approximately $1.552 billion as of today.

Recent performance shows that while XRP ETF capital flows have experienced periodic slowdowns, they have not remained in a state of sustained outflow. This implies that institutional demand for XRP allocations persists. The continuous influx of ETF capital not only provides a new source of liquidity for XRP but also refocuses investor attention on its potential value as an institutional digital asset allocation tool.

Naturally, these ETF inflows have also driven a sustained rise in XRP’s price. Today, XRP rebounded to a high of $1.70. If ETF inflows continue, XRP could potentially return to the $2.00 mark by the end of the month.

The exchange has hired White & Case as restructuring counsel, with a detailed roadmap expected by Sept. 9.

Source link

Ripple CEO Brad Garlinghouse spoke for the first time after attending a crypto meeting at the White House earlier this week and joining the CFTC’s Innovation Advisory Committee, which he calls “the Olympic rules of crypto.”

He noted that even though there were numerous participants from the traditional finance world, the conclusion was unanimous – old rules do not work under the current market environment.

Garlinghouse Speaks Out

Aside from the big price moves over the past week, the other notable development, which might have actually influenced the market revival, was the gathering at the White House organized by the Trump administration. The POTUS met with executives from Coinbase, Ripple, Gemini, and other big crypto companies, as well as the chairmen of the SEC and CFTC.

Perhaps the most important part of the agenda was the highly anticipated CLARITY Act. Policymakers continue to fight over the key legislation, which has failed to garner support from Democrats. As reported, Trump called on Congress to pass a “fair version” of the bill as it would help keep the US in front of China.

The legislation passed the House of Reps in July 2025 but stalled in the Senate over issues such as ethics provisions, stablecoin rewards, and tokenized equities. Garlinghouse said after the event that it was “great to be back at the White House” alongside Trump, CFTC’s Mike Selig, and SEC’s Paul Atkins.

He said that the big picture is clear since 1 in 4 Americans own digital assets: crypto “isn’t a fringe industry. And Washington, DC, knows the crypto voter is alive and well.”

“This President’s incredible commitment to innovation and leadership around digital assets in the US has been profound. The future is bright,” his post concluded.

After the CFTC Event

Garlinghouse also spoke after the CFTC meeting, noting that all parties involved, including those from the TradFi world, believe the current written regulatory rules represent a different era and “aren’t good enough” for the current one. It’s not enough for business, nor for innovation, he added.

He referred to an old open letter he wrote in 2019 in which he urged the US authorities to create clearer rules for crypto. Seven years later, the industry is still waiting. On the plus side, he believes the Trump administration, alongside some appointees like Selig, and a “myriad of bold leaders in Congress,” are finally on the right track as the industry has “never been closer” to such rules.
