TLDR:

  • Binance recorded two XRP whale outflows on February 6 and February 27, totaling roughly 74 million tokens withdrawn.
  • The February 27 withdrawal of 44 million XRP stands as one of the largest single-day outflow events in the tracked data.
  • Negative netflow across 15 exchanges signals that large XRP holders moved assets away from active trading platforms.
  • Reduced XRP supply on Binance eases available selling pressure, a pattern analysts monitor for potential market shifts.

XRP whale activity on Binance has drawn attention after two notable outflow events within a single month. On February 27, approximately 44 million XRP left whale wallets on the exchange.

Earlier, on February 6, around 30 million XRP were withdrawn from the same platform. Both movements were monitored across 15 major crypto exchanges.

These back-to-back outflows have led analysts to examine how large investors are currently repositioning their holdings.

Two Consecutive Binance Withdrawals Mark a Notable February Trend

A chart tracking daily XRP whale wallet net flows across 15 exchanges documented both withdrawal events. The data showed a rise in negative netflow, meaning the digital asset was moving out of exchanges. Market analysts typically read outward flows from exchanges as a bullish signal for an asset.

The February 27 outflow of 44 million XRP ranks among the largest single-day events in the charted data. It followed the February 6 withdrawal of roughly 30 million XRP from the same exchange.

Together, both outflows account for a combined removal of approximately 74 million XRP from Binance. Both events originated from the same platform within the same calendar month.

Analyst Amr Taha noted the rise in negative XRP whale flows from Binance in a market update post. The data suggests large holders moved assets off the exchange rather than positioning for near-term selling. These movements reduced the supply of the token available for active trading on the platform.

In contrast, positive netflow reflects the asset moving into exchanges, which raises available supply on a platform. A higher on-exchange supply generally creates more conditions for selling pressure to build.

February’s trend moved in the opposite direction as whale withdrawals drove Binance supply lower. Analysts use this contrast in flow direction to assess broader market conditions.

Falling XRP Exchange Supply and What the Outflow Data Reveals

When XRP exits a major exchange like Binance, the coins available for active trading decline. Fewer tradable coins on the platform can ease the selling pressure that typically pushes prices lower. If buying demand holds steady as supply falls, the market may adjust upward to reflect this change.

Binance ranks among the most actively traded crypto exchanges globally by volume. Whale movements from this platform tend to carry more market weight than those from smaller exchanges.

Two large outflows from the same exchange within one month is a pattern analysts take note of. This suggests multiple large holders acted in the same direction within a short window.

The February data shows a consistent outflow pattern across both recorded events. The February 6 and February 27 withdrawals both moved in the same direction, reinforcing the overall trend. Repeated outflows in the same direction over a short period carry more analytical weight than a single event.

Following both withdrawals, XRP available for trading on Binance has measurably dropped. Whether this leads to any market response will depend on whether demand holds or grows over time.

The outflow data reflects where large holders are placing their assets rather than forecasting price direction. It remains a relevant on-chain signal for those tracking whale behavior across crypto exchanges.

AI Model Finds 22 Firefox Vulnerabilities in Two Weeks

Published

on

Nexo Partners with Bakkt for US Crypto Exchange and Yield Programs

TLDR:

  • Claude Opus 4.6 found 22 Firefox bugs in 2 weeks, 14 flagged high-severity by Mozilla researchers.
  • The 14 high-severity finds equal nearly a fifth of all such Firefox bugs Mozilla fixed in 2025.
  • Claude succeeded in building working exploits in only 2 of several hundred automated attempts.
  • Anthropic spent roughly $4,000 in API credits testing Claude’s exploit development capabilities.

Anthropic’s Claude Opus 4.6 identified 22 security vulnerabilities inside Firefox in just two weeks. Fourteen of those bugs were classified as high-severity by Mozilla. That figure represents nearly a fifth of all high-severity Firefox flaws remediated throughout 2025. 

The findings emerged from a structured research partnership between Anthropic and Mozilla.

Claude AI Uncovers High-Severity Firefox Bugs at Record Speed

The collaboration began as an internal model evaluation.

Anthropic wanted a harder benchmark after Claude Opus 4.5 nearly solved CyberGym, a known security reproduction test. Engineers built a dataset of prior Firefox CVEs and tested whether the model could reproduce them.

Claude Opus 4.6 replicated a high percentage of those historical vulnerabilities. That raised a concern: some CVEs may already have existed in Claude’s training data.

Anthropic then redirected the effort toward finding entirely new bugs in the current Firefox release.

Within twenty minutes of beginning exploration, Claude flagged a Use After Free vulnerability inside Firefox’s JavaScript engine. Three separate Anthropic researchers validated the bug independently. 

A bug report, alongside a Claude-authored patch, was filed in Mozilla’s Bugzilla tracker.

By the time that first report was submitted, Claude had already produced fifty additional crashing inputs. Anthropic ultimately scanned nearly 6,000 C++ files and submitted 112 unique reports to Mozilla. Most fixes shipped to users in Firefox 148.0.

Firefox 148 Ships Fixes as AI Exploit Research Raises New Alarms

Mozilla triaged the bulk submissions and encouraged Anthropic to send all findings without manual validation. That approach accelerated the pipeline significantly. Mozilla researchers have since begun testing Claude internally for their own security workflows.

Anthropic also tested whether Claude could move beyond discovery into active exploitation.

Researchers gave Claude access to the reported vulnerabilities and asked it to build working exploits. The goal was to demonstrate a real attack by reading and writing a local file on a target system.

Across several hundred attempts, spending roughly $4,000 in API credits, Claude succeeded in only two cases. 

According to Anthropic’s published findings, the model is substantially better at finding bugs than exploiting them. The cost gap between discovery and exploitation runs at least an order of magnitude.

The exploits that did work required a test environment stripped of standard browser security features. Firefox’s sandbox protections were not present.

Anthropic noted that sandbox-escaping vulnerabilities do exist and that Claude’s output represents one component of a broader exploit chain.

Anthropic urged software developers to accelerate secure coding practices. The company also outlined a “task verifier” method, where AI agents check their own fixes against both vulnerability recurrence and regression tests. 

Mozilla’s transparent triage process helped shape that approach throughout the research.

BTC slips below $68,000 as dollar posts steepest weekly gain

Bitcoin fails to sustain breakout momentum as rate hikes beckon: Crypto Markets Today

Bitcoin fell to $67,960 by Saturday morning, down 3.4% over the past 24 hours and retreating sharply from the past week’s high. The move fits what has become a recurring script in recent months, with late-week selling dragging prices toward the lower end of the range heading into Saturday.

Majors took the harder hit again. Ether dropped 4.4% to $1,974, solana fell 4% to $84.31, dogecoin lost 2.9% to $0.09, and BNB slid 2.6% to $627. XRP fell 2.2% to $1.37.

The weekly picture tells a more nuanced story though. Bitcoin is still up 3.6% over seven days. Ether has gained 2.6%. BNB added 2.1%. The mid-week surge absorbed the war shock and then some, even if Friday’s pullback took the shine off.

Meanwhile, the dollar posted its steepest weekly gain in a year, strengthening as markets priced in higher energy costs, stickier inflation, and a Fed that has even less room to cut rates. That’s a direct headwind for bitcoin and every other asset denominated against the dollar.

“As tensions escalated in the Middle East last week, investors moved quickly to the safety of the U.S. dollar, which strengthened as markets began pricing in higher energy prices and reignited inflation fears, potentially delaying Federal Reserve rate cuts,” said Björn Schmidtke, CEO of Aurelion, in an email to CoinDesk.

The on-chain data paints a fragile picture beneath the surface. Glassnode data shows 43% of bitcoin’s total market supply is now sitting at a loss. That’s a significant overhang.

As bitcoin recovers, those underwater holders have an incentive to sell into any rally to break even, creating persistent resistance on the way up. It’s one reason the push to $74,000 on Thursday couldn’t hold. Every bounce toward higher prices runs into supply from people who’ve been waiting months to get out.

One bright spot came from stablecoin flows. Messari recorded a 415% jump in net stablecoin inflows to $1.7 billion over the week, with daily transfers up nearly 10%. That’s potentially dry powder waiting to be deployed, and it suggests retail isn’t entirely absent despite the fear-heavy sentiment. Whether that capital rotates into bitcoin or waits for lower prices is the question.

The war continues to set the tempo. The U.S.-Iran conflict showed no signs of resolution this week. Oil remains elevated. The Strait of Hormuz is still disrupted. And the macro backdrop of strong dollar, sticky inflation, and delayed rate cuts is the worst combination for risk assets.

Bitcoin’s week looked impressive in headlines, touching $74,000 mid-week, but the round trip from $68,000 to $74,000 and back to $68,000 is just another lap of the range.

Bitcoin Dip May Not Be Over As Retail Ramps Up Buying: Santiment

Published

on

Cryptocurrencies, Bitcoin Price, Adoption

Retail investors have been scooping up Bitcoin after it slipped below $70,000, but whale activity suggests the price could still head lower if past patterns repeat, according to crypto sentiment platform Santiment.

“The moment Bitcoin hit $74k, these key stakeholders began taking profit,” Santiment said in a report on Friday.

Santiment explained that whales — those holding between 10 and 10,000 Bitcoin (BTC) — “accumulated heavily” between Feb. 23 and Mar. 3, when Bitcoin was trading between $62,900 and $69,600.

Since Wednesday, when Bitcoin climbed past $70,000 and touched $74,000, the cohort has offloaded around 66% of their recent purchases, Santiment said. Meanwhile, retail investors — those holding below 0.01 Bitcoin — have been increasing their positions.

Correction may not be over yet, says Santiment

“When retail buys while whales sell, it typically signals that the correction is not yet over,” Santiment said. Bitcoin is trading at $67,984 at the time of publication, according to CoinMarketCap.

Bitcoin’s price decline led the Crypto Fear & Greed Index to fall 6 points, pushing it further into “Extreme Fear” territory with a score of 12 on Saturday.

MN Trading Capital founder Michael van de Poppe shared a similar outlook, saying a further decline is possible. “If Bitcoin doesn’t find support in this $67-68K region, then we’re likely going to retest the lows for liquidity before bouncing back upwards,” van de Poppe said in an X post on Friday.

Spot Bitcoin ETFs post largest outflow day in three weeks

The decline coincided with US-based spot Bitcoin ETFs posting their largest outflow day since Feb. 12, with a total of $348.9 million in net outflows across the 11 ETF products, according to Farside data.

Bitcoin’s price fell as low as $60,000 on Feb. 6 during its downtrend from the October all-time high of $126,000 before showing a modest recovery. Economist Timothy Peterson suggests this level could be the floor for the time being.

“This valuation level has always marked a bottom for Bitcoin. About 99.5% chance it stays above $60k,” Peterson said in an X post, referring to the Bitcoin Price to Metcalfe Value chart.
