Cardano founder Charles Hoskinson has reignited bullish sentiment with a new Cardano price prediction , using Monero’s latest crisis as a warning for the entire crypto space. Just 24 hours ago, the team behind Qubic revealed they had taken control of over 51% of Monero’s hashrate – a move that exposes the vulnerability of privacy tokens and reinforces the need for decentralized, secure alternatives like Cardano. Qubic has reached over 51% of Monero's hashrate, effectively giving it control of the network. Qubic chose not to launch the takeover yet, proving a powerful theory by action. But this story isn’t over yet. What's next for Qubic and the future of PoW chains? Article below pic.twitter.com/JqQNqpy95j — Qubic (@_Qubic_) August 12, 2025 This gave Qubic the capacity to bypass consensus, sideline competing nodes and prevent them from participating in the network’s transaction validation process, and take full control of the blockchain’s transaction history. Although Qubic emphasized that they did this to reveal the Monero network’s flaws and have no malicious intentions, they still triggered a steep drop in the price of XMR as a result of their actions. This is another reason we built minotaur for Midnight. Multi-resource consensus ensures checks and balances for the consensus providers using different resources from work to stake. Thus no one attack can take over the network https://t.co/NluXl1vxrP — Charles Hoskinson (@IOHK_Charles) August 12, 2025 Hoskinson used this incident to highlight why Midnight, Cardano’s fourth-generation privacy-centered blockchain, is superior to Monero and mentioned a specific feature called Minotaur as the necessary safeguard to prevent this kind of attack. These comments seem to have resonated with the community and seem to have improved the market’s baseline Cardano price prediction as ADA has gone up by nearly 14% in the past 24 hours while trading volumes have more than doubled during this period. Cardano Price Prediction: ADA Could Deliver 300% Gain If This Happens Looking at the daily chart, ADA has hit a key resistance today as it moves near $0.90. The token has been forming a symmetrical triangle for months and could deliver gains of more than 300% if it breaks above this key level. The price has moved above the 200-day exponential moving average (EMA), confirming that ADA is on an uptrend, while the Relative Strength Index (RSI) has climbed above the 14-day moving average. We could set a first bullish Cardano price prediction of $1.30 – ADA’s most recent swing high – and then to around $4 per token following the launch of Midnight and as the Cardano ecosystem continues to grow. This project’s focus is on real-world blockchain applications primarily. As the world continues to embrace decentralized ledgers for multiple applications beyond just finance, the Cardano network has already proven that it can be a reliable alternative to develop these programs. As major cryptos like Cardano edge closer to new all-time highs, secure storage is more important than ever. That’s where Best Wallet (BEST) comes in – one of this year’s fastest-growing crypto presales, offering multichain support, ultra-low swap fees, and a powerful feature set built for both beginners and pros.

The cryptocurrency world has been shaken by claims from Qubic, a project led by IOTA co-founder Sergey Ivancheglo, that it has allegedly seized majority control of the Monero blockchain’s hashrate. According to the team, this milestone was reached on August 11, 2025, after a focused push that lasted several weeks. The development has opened up concerns over Monero’s network security and the vulnerability of mid-cap Proof-of-Work blockchains to incentive-driven takeovers. How Has The Monero Situation Played Out? According to the Qubic team , the attack was carried out using a “useful proof‑of‑work” (uPoW or UPoW) model. Miners channel their CPU mining power toward Monero; Qubic then converts the mined XMR into USDT to buy and burn QUBIC tokens or reward its own validators. This economic design drew a substantial portion of the Monero mining power away from other pools, escalating from under 2% in May and culminating in the claimed 51% threshold by August. Qubic describes this as a strategic experiment not intended to destroy Monero but to test how incentives can be used to shift control over a network. According to reports and mentions on the social media platform X, there was indeed a six-block reorganization on the Monero blockchain, which showed that Qubic does control a large enough hashrate. If Qubic succeeded in gaining and sustaining majority control (over 50%) of the blockchain’s hashrate, the implications could be severe. In such a scenario, Qubic could potentially censor transactions, perform double-spends, and reorganize blocks at will. Such power would allow them to reverse confirmed transactions and undermine the blockchain’s integrity. What Have Experts Said? In response, the Monero developer community noted that chain reorganizations alone don’t confirm a true 51% attack. Luke Parker (lead dev at SeraiDEX) stated that a six‑block‑deep network reorg with block orphaning does not mean a 51% attack was successful. However, it does mean a mining group with a high amount of hashrate got lucky. The CTO of Ledger, Charles Guillemet, also raised alarms regarding the incident. Guillemet warned that sustaining such a dominance could cost $75 million per day in equipment and operations, and that even that might compromise confidence in Monero nearly instantly. Indeed, many in the Monero community are skeptical that Qubic truly sustained such control. According to a post by blockchain engineer Leonardo Faoro, which was also reposted on the social media platform X by Monero founder Riccardo Spagni, miners don’t need a full 51% hashrate to trigger reorgs. They only require about 35% of the hashrate, along with fortunate timing. Monero’s market performance quickly reflected the unease in the hours following Qubic’s claim of majority control. This unease saw its price fall to as low as $245. At the time of writing, Monero is trading at $247, down by 5.3% and 15.2% in the past 24 hours and seven days, respectively. Qubic’s native token, on the other hand, experienced the opposite trajectory. At the time of writing, QUBIC is up by 20.5% in the past 24 hours.

Cardano founder Charles Hoskinson takes to X to highlight the network’s commitment to security. This comes after Cardano-based FluidTokens released a comprehensive 106-page audit report for its lending V3 protocol. Engineering firm Vacuumlabs, known for auditing smart contracts on the Cardano and Ethereum networks, completed the audit of Fluid Token’s V3 lending platform.FluidTokens V3 Lending Platform Audit ReportAfter receiving the final report, FluidTokens shared all 106 pages via a short video on its official X account. The move seeks to promote transparency and build trust within the crypto community.Such openness contrasts with the practices of some crypto projects that keep internal audit reports confidential. However, FluidTokens shared the comprehensive 106-page audit report to highlight its commitment to user safety and project integrity.Hoskinson Highlights Cardano SecurityMeanwhile, Hoskinson seized the opportunity to highlight Cardano’s dedication to security. Quoting FluidToken’s X post, he noted that the Cardano ecosystem takes security seriously.In his view, FluidToken’s audit report serves as evidence that projects within the Cardano ecosystem hold themselves to high security standards.https://twitter.com/IOHK_Charles/status/1955362577468494148This commitment is part of a broader effort to protect users from vulnerabilities that could lead to financial loss. Hoskinson has consistently drawn attention to the network’s strengths, particularly its focus on security.Earlier this week, following a 51% attack on Monero, Hoskinson discussed the mechanisms the Cardano ecosystem has implemented to prevent such incidents from affecting its privacy-focused sidechain, Midnight.According to The Crypto Basic, blockchain project Qubic took control of the Monero network on Tuesday, with its mining pool power reaching 3 GH/s. After the 51% attack, Qubic was able to orphan competing blocks and reorganize the Monero blockchain, among other capabilities.In response, Hoskinson pointed to the Monero attack as a major reason why the Cardano team built the multi-resource consensus protocol Minotaur for the Midnight sidechain .The protocol offers a blend of proof-of-work (PoW) and proof-of-stake (PoS) consensus models, and prevents anyone from gaining control of the network, according to Hoskinson.
Amid the storm over the Qubic/Monero clash, some warn that privacy’s slow fade is picking up speed — first with the fall of Tornado Cash, then the loss of Samourai Wallet, and now, Monero’s latest setback. The Great Privacy Purge On social media, X user Karbon told their 86,900 followers that recent blows to Monero
Monero is facing a purported 51% attack from an AI protocol called Qubic, which is claiming success—but experts aren’t convinced.
Monero (XMR) is confronting what key voices on X describe as a 51% attack from the Qubic mining pool. Bitcoin developer Peter Todd set the tone early, writing: “Interesting. Apparently Monero just had a big reorg too, I assume related to this attack.” When asked whether Qubic had definitively crossed the 51% threshold, Todd cautioned that real-time dominance is hard to pin down: “That’s inherently difficult to measure. PoW is probabilistic.” Monero Under Siege As Qubic Claims 51% Control A widely circulated post from an account styling itself as Coffeinated User sketched the alleged playbook and economics in stark terms: “Qubic just reached 51% share of Monero. This is a huge feat. They will be the first to manipulate a cryptocurrency with a 51% attack . They intend to orphan all blocks from every other miner, making themselves the only mining entity of Monero.” The same post asserted a profit-split and buyback/burn mechanic around QUBIC tokens: “They are 3X more profitable than mining Monero directly. They are giving half the profit to miners and selling the other half of the profit to buy QUBIC and send it to the burn wallet.” It extended the claim into concrete issuance math and dollar figures: “If they mine 100% of the Monero blocks this gives them 432 Monero mined per day. This is $118,342.08 at the current Monero price. They keep 50% of that and give the rest to miners making their profit $59,171.04 of Qubic being burned every day. $414,197.28 burned a week and $1.656 million burned every month. This is insane.” The post concluded with the market-cap juxtaposition: “Qubic a less than 300 million dollar market cap will be the sole miner of a 6 billion dollar market cap coin.” From the XMR community side, the account @monerobull characterized chain conditions as unprecedented and urged a hash-rate mobilization: “Monero just experienced its deepest re-org ever. Everyone head to gupax.io and start mining. qtip has a halving in 20 days, after which they won’t be able to keep this attack going.” Hardware-wallet executive Charles Guillemet, CTO at Ledger , summarized the situation and its implications in a long post that did not mince words: “Monero appears to be in the midst of a successful 51% attack.” He tied the moment to Monero’s adversarial history and exchange de-listings : “The privacy-focused blockchain, launched in 2014 and long targeted by governments and 3-letters agencies, is already banned from most major centralized exchanges.” On the attacker’s capacity, he wrote: “The Qubic mining pool has been amassing hashrate for months and now controls a majority of the network. A major chain reorganization was detected this morning. With its current dominance, Qubic can rewrite the blockchain, enable double-spending, and censor any transaction.” Guillemet also injected a jaw-dropping back-of-the-envelope cost: “Sustaining this attack is estimated to cost $75 million per day.” He warned of the incentive collapse for honest miners—“Other miners are left with no incentive to continue, as Qubic can simply orphan any competing blocks, effectively becoming the sole miner”—and framed the asymmetry: “In effect, a $300 million market-cap chain is taking over a $6 billion one. Monero’s options for recovery are limited, and a full takeover is now possible and even likely.” As to market reaction, he added: “So far, XMR has dropped only 13%.” From within the Qubic project, “Come-from-Beyond” (Sergey Ivancheglo) signaled both triumph and a call for third-party validation: “Looks like #Qubic has achieved 51% over #Monero, we are waiting for independent confirmations. In the meanwhile #Monero team is polishing details of their 51% attack protection.” Responding to earlier accusations about motives, he continued: “Many accused us of being sponsored by 3-letter agencies to attack this anon coin. What do you think now, after we has helped Monero to prepare for its future fights against those agencies?..” Even as Todd underscores that “PoW is probabilistic” and precise majority measurement is elusive in the moment, the chorus of on-the-record claims from both critics and proponents paints a picture of Monero grappling with a live, majority-hashrate challenge—and a community rushing to counter it in real time. At press time, XMR traded at $252.
The research team at cryptocurrency exchange BitMEX has published an analysis of claims that a mining group called Qubic has gained majority control of the Monero (XMR) network. According to information shared by BitMEX Research, a deliberate six-block reorganization (blockchain reorganization) believed to be caused by Qubic has been detected. This reorganization is relatively short, as the target block time on the Monero network is 2 minutes. Analysts noted that there was no evidence of a double-spend attack; rather, it was likely selfish mining aimed at obtaining higher block rewards. Data shows that Qubic initially controlled approximately 20% of the Monero network, but has increased this share to over 30% through hashrate leasing. BitMEX noted that while Qubic hasn't reached a 51% majority, theoretically exceeding the 33% threshold could make selfish mining profitable as long as the coin's price remains stable. Related News: Analysis Company Reveals: Those Holding This Altcoin Are Not Selling Analysts, noting that Qubic also has its own token, QUBIC, noted that these activities may be aimed at increasing the token's price, but the ultimate goal is unclear. Qubic, in a published article, claimed to control more than 51% of the Monero network. BitMEX, however, is skeptical of this claim. Analysts emphasized that Qubic's ultimate goal could be to capture all of Monero's block rewards, but it's unclear whether this will be possible. If this happens, the value of Monero could plummet. BitMEX also advised exchanges accepting Monero to increase the number of confirmations required for deposits to mitigate potential risks. *This is not investment advice.

Fears of a network takeover have sent the price of Monero crashing down. And the XMR charts don’t look pretty.
Monero, the leading privacy-focused cryptocurrency, is facing one of the most serious security challenges in its history. Qubic, a project led by IOTA co-founder Sergey Ivancheglo, says it now controls more than 51% of the network’s hashrate . In blockchains secured by proof-of-work algorithms, that's the same method used by Bitcoin, that level of control can allow an attacker to rewrite transaction history, block transactions or carry out double-spend attacks. In a blog post , Quibic described the takeover as an "experiment" that was a "strategic, and at times combative, application of game theory." Developers, miners and security experts are now debating whether the network’s decentralization is as robust as many believed. What is a 51% attack? In a proof-of-work blockchain , miners compete to add new blocks of transactions to the chain. If one group controls more than half of the total computing power, they can outpace every other participant. That level of control opens the door to a range of capabilities that can undermine confidence in the network. These include chain reorganizations, commonly abbreviated to "reorg," which involves replacing previously confirmed blocks with new ones. It also covers double spends, meaning sending the same token twice, Arguably the most impactful part of a 51% attack is censoring transactions —preventing some payments from being confirmed — which is particularly pertinent in the case of Monero given its focus on privacy These attacks are not theoretical. Ethereum Classic was hit several times in 2020 , costing millions. Bitcoin Gold faced similar incidents in 2018 and 2020. Smaller tokens like Verge have been targeted and destabilized. Why Monero is still at risk Monero uses the RandomX algorithm to discourage mining using application specific integrated circuits (ASICs), encouraging CPU mining instead. This design was meant to keep the network decentralized. That is why Qubic’s rapid rise is so significant. From less than 2% of Monero’s hashrate in May, it grew to more than 25% by late July, and now claims to have crossed the 51% threshold. Qubic runs a “useful proof-of-work” system that turns Monero mining rewards into USDT, then uses those funds to buy and burn its own QUBIC tokens. The mechanism is unusual, combining a mining strategy with a token supply sink. And it has steadily increased Qubic’s control over Monero’s hashpower. Ledger CTO Charles Guillemet said that "sustaining this attack is estimated to cost $75 million per day," before adding that while it is potentially lucrative, "it threatens to destroy confidence in the network almost overnight. Other miners are left with no incentive to continue." BitMEX research added : "Qubic say the end goal is to takeover all the block rewards of Monero, which essentially means full and sustained selfish mining. It is not clear whether they can actually achieve that. If this can be achieved, the value of the coin may fall." It did. Monero's XMR is currently trading at $252, down 6% over the past 24 hours to compound a 13.5% decline over the past seven days. What does this mean for Monero? In the blog post, Qubic said the takeover was not about breaking Monero, but about proving that economic incentives and a coordinated mining strategy can give a smaller protocol effective control over a much larger one. The experiment, Qubic says, was to test whether mining resources could be profitably diverted from a target network into another protocol’s economic loop. At its peak, Qubic claims its Monero mining was nearly three times more lucrative than traditional Monero mining. A restructuring of its reward system, approved by its community, boosted payouts to its validators and drew miners away from other Monero pools. Qubic’s first push for majority control was met with sustained distributed denial-of-service (DDOS) attacks that disrupted peripheral services for over a week but failed to take down its core network. Those DDOS attacks continued on Tuesday, Ivancheglo revealed on X, in what he decribes as "Monero Maxis returning the favor." Qubic claims it has so far stopped short of fully taking over consensus, citing concerns about the potential impact on XMR’s price. Are other blockchains vulnerable to attack? Bitcoin’s hashrate is so high that a 51% attack would be prohibitively expensive. But mid-tier proof-of-work coins are more vulnerable. The cost of gaining majority hashpower on Monero, Ethereum Classic or Bitcoin Gold is far lower. Privacy-focused coins face an added challenge. Their censorship-resistant nature means that if one party controls the network, it undermines the very privacy they are designed to protect.
