Из жизни альткоинов

Управление по финансовым услугам Мальты (MFSA) сообщило о мошенниках, которые от имени ведомства рассылают криптотрейдерам письма с требованием заплатить штраф за рыночные манипуляции с цифровыми активами.

Председатель Федеральной резервной системы США (ФРС) Джером Пауэлл (Jerome Powell) признал, что цифровые активы уже становятся мейнстримом, поэтому для стейблкоинов пора создавать специальную правовую базу.

On-chain data shows the US-based exchanges have seen a reversal in their Bitcoin volume dominance. Here’s what this trend led to last time.

Bitcoin US Vs Off-Shore Ratio Has Been Rising Recently

As pointed out by CryptoQuant author Axel Adler Jr in a new post on X, the US vs. Off-Shore Ratio is currently showing a reversal. The “US vs. Off-Shore Ratio” keeps track of the ratio between the Bitcoin volume involved in trades on the American platforms and that on the foreign ones.

When the value of this metric is greater than 1, it means the US-based exchanges are dominating in terms of volume compared to the rest of the world. On the other hand, it being under the mark suggests off-shore platforms are witnessing a higher amount of trading activity.

Now, here is the chart shared by the analyst that shows the trend in the Bitcoin US vs Off-Shore Ratio over the last few years:

As is visible in the above graph, the US vs. Off-Shore Ratio witnessed a sharp increase in 2023 and broke above the 1 level, signaling the return of dominance from the US-based exchanges. It has since remained in this region, with a second leg up occurring in the second half of last year.

While the indicator continued the trend from last year and observed a rise to an even higher peak in January, it has since noted a sharp reversal. Though, despite the drop, its value continues to be above the 1 mark, which suggests American platforms are still the dominant ones in Bitcoin volume, albeit to a much smaller degree.

From the chart, it’s apparent that very recently, the Bitcoin US vs. Off-Shore Ratio has shown early signs of another turnaround, as its value has marked a small improvement.

In the graph, the analyst has highlighted the previous instance of the indicator witnessing such a reversal. This last turnaround, which came when the asset was trading around $60,000, led into a rally that took the price to new highs.

Something that’s still missing for the indicator’s reversal at present to be confirmed is the trend in the 90-day and 365-day simple moving averages (SMAs). During the previous turnaround, the two lines observed a crossover.

Recently, these SMAs have been approaching each other, so it’s possible that another crossover may be coming soon. Going by the previous trend, the increase in activity on the American exchanges could once again prove to be bullish for Bitcoin. As of now, though, the crossover hasn’t been confirmed.

At the time of writing, Bitcoin is floating around $84,000, up more than 10% in the last seven days.

Бывший председатель Комиссии по ценным бумагам и биржам США (SEC) Гэри Генслер считает, что в будущем наилучшие позиции останутся у биткоина, а курсы большинства альткоинов и мемкоинов зависят от настроения рынка.

Управляющий партнер и вице-президент ELS Group Андрей Евстифеев рассказал, что последние годы россияне все чаще ищут альтернативу банковским вкладам, предпочитая цифровые активы и металлические счета.

Bitcoin Core v29 has just been released, signaling the resolution of a debate within the Bitcoin community that stretches all the way back to the days when Satoshi Nakamoto was still actively discussing new ideas on Bitcointalk. The announcement arrived with a statement in the release notes explaining that, starting with v28.0, the “-mempoolfullrbf” startup option had defaulted to 1 and that, with widespread adoption of the practice, the option was now removed entirely.

The official notes read: “Starting with v28.0, the -mempoolfullrbf startup option was set to default to 1. With widespread adoption of this policy, users no longer benefit from disabling it, so the option has been removed, making full replace-by-fee the standard behavior. (#30592)”

In response to this milestone, longtime Bitcoin developer Peter Todd posted via X, “The battle for Full-RBF is finally over.” He was soon asked by a user how long the struggle had lasted, and Todd replied, “Over a decade… 2013 IIRC. Even longer if you count it from when Satoshi first mentioned RBF in Dec 2010.”

Bitcoin Core v29 Declares Full-RBF The New Standard

Full Replace-by-Fee (Full-RBF) is a policy that allows any unconfirmed transaction sitting in the mempool to be replaced by another transaction that pays a higher fee, regardless of whether the initial transaction signaled replaceability. This policy builds on earlier discussions dating back to December 2010, when Satoshi Nakamoto briefly floated the idea of allowing transaction replacement as a means to prevent network congestion and address stuck transactions. Several years later, in 2013, Peter Todd began advocating more forcefully for RBF as a remedy to the common user complaint that low-fee transactions could remain unconfirmed for hours or days if the network was overloaded.

The debate that developed around Replace-by-Fee, and later Full-RBF, became a flashpoint for broader questions about Bitcoin’s purpose, security, and everyday usability. On one side were those who saw transaction replacement as an inevitable and beneficial evolution of Bitcoin’s transaction-processing logic. They argued that it aligns well with Bitcoin’s fee market incentives—miners naturally choose higher-fee transactions—and that it provides greater reliability for users by allowing them to “bump” a transaction fee after realizing their initial fee might be too low.

The counterargument came mostly from merchants and services that relied on so-called zero-confirmation transactions, often used for small payments such as buying a coffee or making quick point-of-sale purchases. Opponents of Full-RBF argued that enabling any unconfirmed transaction to be replaced would make zero-confirmation payments too risky, as malicious actors could double-spend by broadcasting a conflicting transaction with a higher fee.

This issue of zero-confirmation payments—commonly called 0-conf—was particularly divisive. Some merchants considered 0-conf good enough for low-value transactions because the incentives to cheat were minimal. However, developers in favor of RBF argued that 0-conf was never a sound security assumption in the first place, because double-spends were theoretically possible regardless.

The introduction of opt-in RBF in 2016 (via BIP125 and Bitcoin Core 0.12.0) formalized this debate: transactions could include a flag signaling their willingness to be replaced, but miners and nodes could still choose whether to honor the replacement. Bitcoin Core has steadily moved toward broader RBF use in the years since, culminating with v29 in April 2025, which fully adopts the policy network-wide by default.

The debate also spilled over into other Bitcoin forks and communities. Bitcoin Cash, which emerged in 2017 with a focus on larger block sizes and low fees, largely rejected RBF in favor of preserving zero-confirmation features. Proponents of Bitcoin Cash often saw Full-RBF as a step in the direction of turning Bitcoin into a strictly “store of value” system, rather than a payment network for everyday transactions. Bitcoin Core developers, for their part, tended to argue that Bitcoin’s long-term scaling relied on second-layer solutions, such as the Lightning Network, where near-instant transactions are possible without relying on unconfirmed on-chain payments.

Over the years, miners generally leaned toward policies that maximize fees and network efficiency, though some were initially hesitant to adopt Full-RBF if it threatened to fracture the network into competing mempool policies. Merchants, payment processors, and Bitcoin ATM operators that favored zero-confirmation transactions resisted Full-RBF for obvious reasons: it undermined the trustworthiness of unconfirmed payments. Yet the momentum toward broader adoption of RBF never ceased, supported by the argument that it reflects the economic reality of how miners and users interact with the fee market.

Now, with Bitcoin Core v29, the final step has been taken: Full-RBF is the standard behavior, with no option to disable it. That shift closes a decade-plus chapter of argument and technical back-and-forth, one that Peter Todd alludes to when he says it goes back “even longer if you count it from when Satoshi first mentioned RBF in Dec 2010.”

At press time, BTC traded at $84,024.

При вложениях в криптовалюту инвесторы хотят купить подешевле, а продать подороже. Один из способов сделать это — воспользоваться волновой теорией Эллиотта, которая дает ориентиры на начало и конец роста и коррекции.

Semler Scientific is looking to raise $500 million in new securities after settling a large case with the Department of Justice, according to company filings. The health care technology company will use some of the money to expand its crypto holdings, which are already in excess of 3,000 coins.

Company Enters $30 Million Settlement With Justice Department

As per recent Securities and Exchange Commission (SEC) filings, Semler Scientific has reached a $29.75 million settlement with the Department of Justice regarding marketing practices for its QuantaFlo product. The probe, which started in 2017, centered on potential violations of federal anti-fraud laws regarding the manner in which the company marketed its flagship product.

The settlement negotiations progressed in recent months following years of cooperation with several subpoenas. The deal is not complete yet, according to the company’s Tuesday SEC filing, but Semler has already obtained a way to finance the payment.

Coinbase Loan To Fund Settlement Without Selling Bitcoin

Instead of liquidating its cryptocurrency holdings, Semler intends to use a loan from Coinbase to settle the DOJ case. The loan will be secured by the company’s large Bitcoin reserves, which stand at 3,190 BTC valued at about $267 million at current market prices.

This funding strategy enables Semler to satisfy its legal requirements without liquidating its cryptocurrency holding. With Bitcoin as collateral, the company can preserve its balance sheet strength while fulfilling the settlement needs.

Half-Billion Dollar Securities Filing Points To Bigger Crypto Plans

Apart from the settlement expenses, Semler has submitted an S-3 registration to the SEC to sell $500 million worth of securities. The filing indicates the company is not merely raising cash to pay the DOJ settlement but wants to increase its Bitcoin holding substantially.

The action is made at a time when other businesses continue to accumulate Bitcoin into their coffers. According to reports in the filing, Michael Saylor’s firm recently bought 3,450 bitcoins worth $286 million, increasing its holdings to 531,640 bitcoins. Another company, Metaplanet, acquired $26 million worth of Bitcoin over the same time.

Market Analysts Remain Bullish Despite Price Swings

The timing of Semler’s intended Bitcoin buys is during market volatility yet also forecasts of extreme price appreciation. An analyst, who goes by the handle “Titan of Crypto” forecasted Bitcoin to hit $137,000, although no timeframe was given for that price level.

The healthcare technology firm has not indicated precisely when it will finish its securities offering or make further Bitcoin buys. Nevertheless, the SEC filing clearly indicates that adding to cryptocurrency holdings is still a priority in addition to paying for the DOJ settlement.

Recent on-chain data has revealed that Dogecoin whales are back in the market and accumulating tokens en masse. Based on the current state of the market, these whales appear to be taking advantage of low prices to buy more DOGE tokens in hopes of an imminent rally.  

Dogecoin Whales Are Back In Action

In an X (formerly Twitter) post on April 15, crypto analyst Ali Martinez announced that Dogecoin whales have returned to the scene with significant accumulation activity after initiating a massive sell off previously. These large-scale crypto holders reportedly acquired over 800 million DOGE tokens within a 48-hour period. With Dogecoin trading around $0.16 at the time, the total value of the purchase amounted to roughly $130 million. 

The analyst presented a chart which tracks the holdings of wallets containing 1 billion DOGE or more, revealing a sharp increase in accumulation beginning around April 9, with holdings remaining elevated through April 14. 

This influx of whale interest aligns closely with an upward movement in Dogecoin’s price, which rose from approximately $0.153 to around $0.165 during the same period. The timing and scale of this accumulation also suggest a shift in sentiment and confidence among these big players, often seen as an indicator of potential upward momentum.

Over the past month, the Dogecoin price has declined to $0.154 after dropping by 11.3%. Considering the meme coin’s significantly low price compared to its previous high earlier this year, it appears that Whales could be taking a buy-dip approach to accumulate as many tokens as possible during the current market downturn. 

Notably, the recent 800 million DOGE acquisition isn’t the only large-scale whale purchase this month. On April 11, Martinez reported that whales had also scooped up over 80 million DOGE, a buy valued at approximately $13 million at the time. 

This surge in whale activity suggests growing optimism among large traders, possibly reflecting expectations of a price recovery. Supporting this outlook. Martinez revealed that approximately 72.13% of long-term Dogecoin traders are currently holding long positions. This metric reflects a firm conviction in Dogecoin’s potential to rally, especially if broader market conditions begin stabilizing. 

DOGE Price Gears Up For Higher Pump

In one of his latest analyses on X, Trader Tardigrade, a well-known crypto analyst, predicted that the Dogecoin price is gearing up to challenge the downtrend and rebound higher. The analyst unveiled that the meme coin is currently forming a prolonged Symmetrical Triangle pattern on its chart, indicating the possibility of a bullish turnaround.

According to Trader Tardigrade, the longer Dogecoin’s consolidation is within this Symmetrical Triangle, the stronger its momentum grows. This supports the possibility that once Dogecoin breaks out of the triangle, it could see a higher pump to new levels.

The Cardano Foundation has formally announced a new partnership with the Pontifical Catholic University of Rio de Janeiro (PUC-Rio), a top-ranked Brazilian university renowned for its contributions to research and development. The collaboration, revealed on April 15, will concentrate on the advancement and practical application of blockchain technology, specifically within the energy sector in Brazil.

Cardano Partners with Top Brazilian University

PUC-Rio is recognized as one of the top five private universities in the world for excellence in research and development, and it has a broad history of partnerships within the energy industry. The establishment of this collaboration follows previous cooperative efforts between PUC-Rio and the Brazilian state-owned enterprise Petrobras, as well as the Cardano Foundation’s own involvement with Petrobras on blockchain-driven initiatives.

Through this new endeavor, PUC-Rio’s Ledger Labs—a research group concentrating on the utilization of DLT in finance and business—will receive support from the Cardano Foundation to explore various aspects of blockchain implementation. According to official statements, the initial areas of focus will include blockchain economics, decentralized finance (DeFi), governance of decentralized autonomous organizations (DAOs), and digital assets.

“At the core of blockchain advancement are education and innovation. Through our collaboration with esteemed academic institutions like PUC-Rio, the Cardano Foundation ensures that the next generation of developers, industry leaders, and regulators can harness this transformative technology to its fullest potential—creating solutions that address real-world challenges and drive positive global impact,” Cardano Foundation CEO Frederik Gregaard commented.

The immediate emphasis of this alliance will be directed toward developing blockchain-based solutions that enhance production, consumption, and overall value chains in renewable energy fuels. Joint research and pilot projects in cooperation with Petrobras are expected to delve into specific methods of applying Cardano’s blockchain infrastructure to processes such as tracking and verifying energy outputs, optimizing workflows, and ensuring robust data integrity.

Ledger Labs at PUC-Rio will serve as the operational base for these studies. Leonardo Lima, Vice-Dean of the university and head of Ledger Labs, noted that the scope of the partnership will also encompass philanthropic endeavors geared toward social impact. “Our partnership with the Cardano Foundation marks the beginning of the development of a series of use cases, not only in the energy industry but also in the field of philanthropy, with a focus on social impact projects,” he said.

Beyond the technological and scientific research, the partnership aspires to enrich PUC-Rio’s blockchain ecosystem by hosting joint events, supporting student-led social projects, and inviting other organizations to collaborate on emerging blockchain strategies. A significant part of this development will occur through A.L.B.A (Ada Labs for Blockchain Applications), an arm of Ledger Labs that is expected to integrate standards previously introduced at the Universidad Tecnológica Nacional (UTN) in Buenos Aires, Argentina.

The Foundation’s current expansion in Brazil reflects its growing footprint in the region. “Our partnership with PUC-Rio marks the Cardano Foundation’s second collaboration with a Brazilian entity this year. Last month, we announced our partnership with SERPRO, the world’s largest public IT company, and we have been collaborating with Petrobras, Brazil’s state-owned energy company, since 2023,” said Rafael Fraga, LATAM Business Development Lead for the Cardano Foundation.

Over the past week, Solana has maintained a notable bullish performance, rising by more than 20% after a recent drop to the $100 support zone on April 9. While SOL has recovered its upward trend, key metrics show a major area of interest in its price dynamics for a significant number of investors.

Massive URPD Supply Cluster Amid Solana’s Price Fluctuation

Glassnode, a leading on-chain data and financial platform, has outlined a crucial shift in Solana’s price dynamics as it attempts to overcome crucial resistance areas. In the recent analysis shared on X, Glassnode points to several price zones that are vital for the altcoin’s future performance.

After delving into the UTXO Realized Price Distribution (URPD) indicator, the platform reveals that SOL has formed the largest supply cluster in recent history. This notable accumulation of investor-held SOL around a particular price point identifies a key region of interest that may serve as a crucial support or resistance zone. 

According to Glassnode, SOL’s URPD shows that the cost basis has significantly changed in the last 2 days as the largest supply cluster emerges. Looking at the data, the massive supply cluster occurred at the $129.79 level, where investors accumulated more than 32 million SOL, representing 5% of the altcoin’s overall supply.

With market participants heavily concentrated in this range, Solana might be approaching a pivotal moment where the direction of the price could be determined by buyers’ or sellers’ domination of the trend. During future declines, this zone may serve as support, reflecting strong investor activity at the price level.

The second largest supply cluster is located at $144.54. At this level, investors purchased over 27.5 million SOL, which stands as a significant barrier to price upswings and could also act as robust support if the altcoin surpasses the level.

Below the $129 mark, Glassnode noted that the next support for Solana is at $117.99, where 18 million SOL, or 3% of the total supply, were acquired by investors. With $129 acting as the crucial pivot zone, $144 may serve as resistance in the short term and $117 as the bottom bound of the price range.

SOL’s Display Upside Potential To Higher Levels

Even though SOL’s price has been facing volatility, now might be the right time to purchase the dip as the altcoin gears up for an upward move. Ali Martinez, a crypto analyst and trader, predicts that Solana is poised for a strong rebound.

Martinez’s forecast is based on a TD Sequential buy signal on the weekly chart. A TD Sequential buy signal is an indication of growing momentum, which implies that the current correction could be nearing its end.

This is the second time in 1 week that the indicator has flashed a buy signal in the weekly time frame in spite of waning price performances. During the first signal, Martinez noted that SOL must maintain its position above $95 and breach $121 to set the stage for a rally to the $147 price level.

Crypto analyst Mindfully Lost has revealed price action levels for XRP and Dogecoin. He mentioned the resistance and support levels to keep an eye out for these heavy hitters amid this market downturn. 

Price Action Levels For XRP And Dogecoin

In a TradingView post, Mindfully Lost stated that the range between $2.20 and $2.24 is the resistance level for the XRP price, noting that there is low volume around this area. Meanwhile, he revealed that the range between $1.92 and $1.95 is the major support level for the altcoin, as there is high volume around this area. The analyst told market participants to expect some consolidation through these levels. 

Meanwhile, for Dogecoin, the crypto analyst revealed the range between $0.167 and $0.169 as the major resistance level for the meme coin, noting that there is low volume around that area. Meanwhile, the range between $0.148 and $0.151 is the major support level for DOGE, as there is high volume around that zone. 

Besides Mindfully Lost, other crypto analysts such as CasiTrades have highlighted the $2 zone as being important for the XRP price. In a recent X post, CasiTrades remarked that XRP is still struggling at the $2.17 resistance, but lower supports are still valid. 

The analyst revealed that there have been multiple failed attempts to break the $2.17 resistance. She added that this level continues to act as a strong ceiling and that if this rejection continues to play out, then the support at $1.90 and $1.55 remains firmly in play, indicating that the altcoin could still drop below $2. 

XRP & DOGE Whales Have Been Busy

XRP and Dogecoin whales have been busy amid this market downtrend. In an X post, Martinez revealed that crypto whales have sold over 370 million XRP since the start of the month, presenting a bearish outlook for the altcoin. On the other hand, Dogecoin whales are actively accumulating. 

The analyst revealed that these whales have bought over 800 million Dogecoin in the last 48 hours, presenting a bullish outlook for the foremost meme coin. Binance traders are also betting on a bullish reversal for DOGE as Martinez revealed that 72.13% of traders on the crypto exchange with open positions are currently long. 

A bullish reversal for XRP and Dogecoin will largely depend on the Bitcoin price action, with the flagship crypto looking likely to drop lower at the moment. Meanwhile, crypto analysts Ali Martinez and Master Kenobi have highlighted how important it is for the Dogecoin price to hold the $0.14 support.

Martinez stated that the foremost meme coin could drop below $0.10 if it loses that support level. Master Kenobi suggested that a drop below the $0.14 support could mark the end of Dogecoin’s bull run.

UK Government Minister Lucy Powell’s X account was hacked on Tuesday morning in a cryptocurrency scam for a phony “House of Commons” digital currency, multiple news sources disclosed Wednesday.

Hackers Create Fake Government Cryptocurrency

The cyberattackers put up a number of posts on Powell’s authenticated account stating “$HCC” was “a people-powered digital currency putting people’s power to the blockchain.”

Powell, the leader of the House of Commons and Manchester Central’s representative, has close to 70,000 followers on the platform.

Certain messages added the formal House of Commons logo to give the scam the air of legitimacy. Powell’s office said they “pursued steps promptly to lock in the account and delete deceptive posts” after they became aware of the breach.

Recent letters In Series Of Top-Profile Account Takeovers

This attack follows a pattern of similar hacks targeting public figures with large follower counts. BBC journalist Nick Robinson fell victim to a similar scheme earlier this year when hackers used his account to promote a fake cryptocurrency called “$Today.”

Robinson reported clicking on what he thought was a legitimate email from the social media platform, which gave hackers access to his account.

‘Pump And Dump’ Scheme Yields Limited Returns

Luke Nolan, a senior research associate at digital asset manager CoinShares, recognized the hack as a traditional “pump and dump” scheme.

In this widespread scam, perpetrators create worthless cryptocurrencies, artificially pump up their price, persuade others to invest, and then sell their shares for profit before the price crashes.

Even though the scam targeted a high-profile government official’s account, the scam was relatively unsuccessful. The imposter coin attracted only 34 transactions, with the scammers making around £225 in profits.

Growing Trend In Account Hacking

Action Fraud also reports that there has been a high incidence of social media and email account hacking in 2024 to date, at 35,343. Security experts say they suspect most attacks start with emails that have a link to fake websites that pilfer passwords or gain unauthorized system access.

Passwords can also be accessed via data breaches where users’ information is hacked and put on sale online. It takes scammers just a few hours to create and roll out counterfeit cryptocurrencies, and then they move swiftly once they have access to an account.

The UK Parliament official said they “take cyber security extremely seriously” and give members advice on how to manage online safety, but refused to disclose specific information on their cybersecurity practices.

Action Fraud advises people to safeguard their accounts by registering two-step verification and adopting hard, different passwords of three randomly chosen words.

Powell has been a leader of the House of Commons since Labour came to power in the summer. Her work entails scheduling the government’s legislative programme and safeguarding the rights of backbench MPs.
