Virtual criminals have turned thousands of web pages into crypto mining machines without the owners' knowledge, illegally. Over 3,500 sites were infected just in July of last year in Latin America. The warning comes from the digital security company ESET, based on data collected throughout 2025.

The illegal operation occurs precisely when Brazil establishes stricter rules for the digital asset market under the supervision of the Central Bank.

Risks related to quantum computing are impacting the relative valuation of Bitcoin compared to gold, according to analyst Willy Woo. The trend of Bitcoin appreciation against the precious metal, which lasted for 12 years, was broken after quantum computing came onto the market's radar.

According to Woo, a sufficiently advanced quantum computer could, in theory, discover private keys from exposed public keys. The central point is the possible reacquisition of about 4 million BTC considered 'lost', a volume that would surpass institutional purchases over the last eight years.

The recent recovery of BTC may be hiding a worrying signal. The price of Bitcoin rose nearly 9% between February 12 and 15, creating the impression that the worst of the correction had passed.

However, the advance is already showing signs of weakening. Now, leverage data, momentum indicators, and on-chain profit trends suggest that this movement may have increased the risk of a decline, rather than ending it.

A 9% rise in Bitcoin attracted nearly $2 billion in bullish bets

Between February 12 and 15, Bitcoin recorded a rise of around 9%. Meanwhile, futures traders aggressively increased their bets on new advances. The total open interest, aimed at the aggregate volume of open futures contracts, rose from $19.59 billion to $21.47 billion — an increase of approximately $1.88 billion, or about 9.6%, between February 13 and 15.

In mid-February, discussions about Dogecoin (DOGE) became significantly more active. DOGE investors expect a strong recovery of the memecoin after a decline of over 75% in its value since last year.

Several factors have driven this new wave of optimism. The main question remains whether these elements will be sufficiently solid to sustain a prolonged recovery in prices.

Elon Musk's influence on DOGE is gaining strength again

Data from LunarCrush, a social intelligence platform aimed at crypto investors, indicates that mentions of Dogecoin increased by 33.19% in the last month compared to the previous month.

Altcoin markets remain highly reactive as February enters its third week. Several important tokens are near critical points of technical inflection, with external factors that could define the next direction of prices.

In this scenario, BeInCrypto analyzed three altcoins that investors should watch: Arbitrum (ARB), traded at $0.11 and close to the historical low of $0.094; Injective (INJ), with a 98% correlation with Bitcoin and a risk of falling to $2.65; and Bitcoin Cash (BCH), which is testing resistance at $574 before the Bitcoin Cash Toronto event on February 17.

A Coinbase enfrenta críticas de usuários após muitos participantes do concurso de previsões “Big Game Challenge” do Super Bowl relatarem atrasos ou ausência de pagamentos, mesmo após serem considerados aptos a receber parte do prêmio em Bitcoin divulgado.

As reclamações da comunidade e problemas técnicos evidenciam as dificuldades enfrentadas pelos mercados de previsões, que crescem em popularidade enquanto lidam com desafios regulatórios, operacionais e de infraestrutura.

Usuários relatam prêmios que apareceram e sumiram das contas

No Reddit e em outros fóruns, usuários relataram experiências confusas e frustrantes com o processo de pagamento. Segundo relatos, alguns acertaram previsões no Big Game mas “continuam sem receber”.

Outros apontaram que os ganhos apareceram brevemente no saldo de contas antes de sumirem sem explicação, ou então os valores foram registrados em dólar, mas sem possibilidade de transferência ou acesso.

Entre as insatisfações, alguns classificaram a situação como um “rug pull”, alegando que o aplicativo da Coinbase inicialmente confirmou a vitória após cinco palpites corretos — limiar para elegibilidade —, mas um e-mail posterior indicou que, na verdade, não foram premiados.

“ De acordo com o app da Coinbase, eu tinha vencido o Big Game Predictions com 5 palpites certos, apostando US$ 5 em cada previsão. O aplicativo orientou a aguardar o pagamento. Porém, recebi um e-mail da Coinbase dizendo que não ganhei. Mais alguém acha que isso se parece com um rug pull ou algum tipo de golpe?”, diziam os posts.

Em algumas conversas, equipes de suporte indicaram que as premiações estão retidas até a liquidação de todos os mercados de previsão e inscrições por correio, em conformidade com as regras oficiais do concurso.

Coinbase promete pagamento até 23 de fevereiro

A Coinbase já informou que os vencedores receberão as recompensas em Bitcoin diretamente na conta até 23 de fevereiro de 2026.

No entanto, a falta de transparência e as mudanças de contas têm gerado insatisfação entre usuários que buscam confirmar o status da liquidação.

“Nós compreendemos totalmente a importância disso para você. Os vencedores verificados receberão o prêmio diretamente na conta Coinbase. O valor do prêmio será uma fração de US$ 1 milhão em Bitcoin, dividido igualmente entre todos os premiados. Esperamos que a distribuição ocorra até 23 de fevereiro de 2026”, explicou a Coinbase na X.

Parceira Kalshi também enfrentou problemas de infraestrutura

Essas reclamações surgem no momento em que os mercados de previsões ligados à cripto também enfrentam dificuldades. A parceira Kalshi, responsável pela infraestrutura dos contratos de eventos da Coinbase, enfrentou atrasos em depósitos e transações durante o Super Bowl devido ao tráfego elevado.

“A Kalshi faz todos esses anúncios para o aplicativo, mas não deixa você depositar no dia do Super Bowl, típico”, lamentou um usuário.

A brasileira cofundadora da Kalshi, Luana Lopes Lara, reconheceu a lentidão, mas garantiu aos usuários que os valores estavam “seguros e a caminho”.

"Some deposits are delayed because of the amount of traffic and deposits we're getting," Kalshi cofounder Luana Lopes Lara wrote on X on Sunday evening. "Your money is safe and on the way, it will just take longer to land." https://t.co/8sZcCzXkdq

Esses desafios operacionais mostram que a infraestrutura criada para negociações diárias pode não suportar picos de demanda em grandes eventos.

Pressão técnica semelhante foi observada em outras plataformas do setor durante o campeonato, indicando desafios sistêmicos de escalabilidade em sistemas que oferecem contratos de eventos durante alta demanda.

A repercussão negativa para a Coinbase ocorre em meio a um cenário regulatório e jurídico mais amplo. Órgãos de fiscalização, como o Nevada Gaming Control Board, entraram com ação judicial para impedir os mercados de previsão da Coinbase. Segundo reguladores, eles configuram apostas esportivas sem licença.

Esses processos aumentam a incerteza sobre a situação regulatória dos contratos de eventos, dificultando a expansão e afetando a experiência dos usuários.

Enquanto isso, vozes da própria comunidade cripto defendem que os mercados de previsão avancem além das apostas especulativas de curto prazo.

Líderes como o cofundador do Ethereum, Vitalik Buterin, já alertaram que a dependência excessiva de contratos especulativos pode resultar em produtos com utilidade limitada, recomendando foco em ferramentas de proteção e gestão de riscos.

Recently I have been starting to worry about the state of prediction markets, in their current form. They have achieved a certain level of success: market volume is high enough to make meaningful bets and have a full-time job as a trader, and they often prove useful as a…

A recente onda de críticas à Coinbase evidencia lacunas operacionais e de comunicação que podem surgir diante de uma rápida ampliação de produtos.

O artigo Coinbase enfrenta acusações de “rug pull” após Super Bowl; entenda foi visto pela primeira vez em BeInCrypto Brasil.

The former CEO of Binance, Changpeng Zhao (CZ), revealed details about the breakup with FTX in an appearance on the All-In Podcast. According to him, the cooperation turned into rivalry long before the collapse of Sam Bankman-Fried's (SBF) exchange in November 2022.

CZ stated that Binance invested 20% in FTX in 2019, when the exchange was still an emerging derivatives platform. The relationship deteriorated quickly after reports that SBF was criticizing Binance to regulators in Washington. Binance sold its stake in July 2021, about 18 months before FTX's bankruptcy.

The price of Polygon shows new signs of recovery after weeks of constant selling. Since February 11, POL has accumulated an increase of nearly 13% and, in the last 24 hours, has advanced about 5.4%, maintaining most of its return momentum in the range of $0.095.

At first, the structure resembles the pattern that drove the 90% appreciation of Polygon earlier this year. The price stabilizes, the moment is one of improvement, and buyers are acting close to support. However, now a crucial element is missing. In the last surge, sellers were completely removed from the market. This time, that movement has not yet occurred.

A structured credit manager from the US is pushing the boundaries of TradFi by integrating crypto into real-world financing. Newmarket Capital, responsible for nearly $3 billion in assets, is innovating by creating hybrid loans with mortgages and commercial credit, using Bitcoin (BTC) along with traditional real estate as collateral.

Its affiliate, Battery Finance, leads the development of financial structures that use digital assets to enable credit without requiring the liquidation of clients' investments.

Ethereum is attempting to stabilize after weeks of strong selling pressure. The price is near the $1,950 range, advancing about 6% from its recent low. Meanwhile, the largest Ethereum whales have initiated a significant accumulation movement.

However, short-term traders and derivatives market participants remain cautious, intensifying the debate around the coin's next move.

Largest Ethereum whales accumulate while bullish divergence remains

The price of XRP has struggled to recover in recent days, raising concerns about a possible repeat of the 2021-2022 bear market.

Despite the persistent weakness, a recent fact involving Brad Garlinghouse, CEO of Ripple, may change market sentiment.

XRP may not repeat the past

Brad Garlinghouse has been appointed to the Advisory Committee on Innovation of the Commodity Futures Trading Commission (CFTC). The appointment represents a significant milestone for Ripple and the entire XRP ecosystem. The same regulatory environment that posed challenges to the company for almost five years is now seeking collaboration from the sector.

The Bitcoin (BTC) bear market impacted investors across all segments. Corporate treasuries, large whales, and even governments felt the pressure.

The fall of the currency reduced the value of El Salvador's reserves while default swap contracts reached their highest level in five months, raising concerns about the IMF program and the country's debt scenario.

According to recent data from El Salvador's Bitcoin Office, the nation's reserves total 7,560 BTC, valued at around $503.8 million. Bloomberg reported that the value of the portfolio fell from about $800 million at Bitcoin's peak in October 2025, representing a loss of nearly $300 million in four months.

Bitcoin has always had its function as a store of value questioned due to high volatility. Physical gold, on the other hand, has established itself as the main asset for wealth protection. It is synonymous with predictability and stability in times of crisis.

This contrast, however, is starting to lose strength. Recent data shows a significant change. For the first time in years, the monthly volatility of gold has exceeded that of Bitcoin. This information is included in analyses from JPMorgan. The fact questions the narrative that separates the two assets only by risk.

The price of Bitcoin remains pressured, with a drop of about 1.2% in the last 24 hours and being traded close to $66,000 at the time of this report. Despite occasional recoveries, the overall structure remains fragile.

Now, even large institutions are showing caution in their projections for Bitcoin. New on-chain signals and the behavior of long-term investors indicate that the risk of decline still persists.

The tokenized gold market surpassed US$ 6 billion, advancing significantly amid short-term volatility in physical gold prices.

With investors seeking exposure to real assets through digital infrastructure, tokenized gold has become one of the fastest-growing sectors within the digital asset market.

According to data from Dune, the total market capitalization of tokenized gold has increased by more than US$ 2 billion since the beginning of the year. At the time of this report, the segment was at US$ 6.12 billion.

Fintechs in Argentina welcomed the unprecedented possibility of allowing workers to deposit their salaries in virtual wallets (crypto). However, lawmakers removed this section from the project, a measure seen as favoring the interests of traditional banks.

In negotiations to broaden support for the text, the president Javier Milei's party agreed to exclude the article, despite polls showing that a significant majority of the population prefers to have the freedom to decide where their wages will be deposited.

Some Coinbase users are experiencing a temporary outage that prevents the purchase, sale, or transfer of digital assets on Coinbase.com.

The problem, first reported by the platform on its social media, raised concerns among traders, although the company assures customers that all funds remain protected.

Temporary service interruption prevents Coinbase users from trading.

Coinbase, the largest crypto exchange in the US, confirmed the interruption in a statement released on its official support channel on X, stating:

A new survey from OKX reveals that Americans increasingly find knowledge in financial education and digital assets attractive in a partner, with 21% stating that receiving crypto as a gift on Valentine's Day would be a 'stimulus.'

The data indicates that currently, having financial knowledge has become an evident advantage in the context of relationships.

Millennials and Generation Z redefine attraction based on financial management

The survey conducted with 1,000 Americans shows that 66% believe that knowledge about personal finance makes someone more attractive. The percentage is even higher among younger generations: 76% of Generation Z and 75% of Millennials value financial education in their partners.

Ethereum co-founder Vitalik Buterin classified Russia's invasion of Ukraine as 'criminal aggression.' He advocates for the application of governance principles inspired by crypto to transform the Russian political system.

The statements, released on the eve of the fourth anniversary of the invasion on February 24, 2026, connect blockchain concepts to the long-term security of Europe and Ukraine.

The Russian-Canadian innovator directly refuted interpretations that present the conflict as morally ambiguous. He emphasized that the invasion led by Russia finds no justification.

MEXC, the fastest-growing global cryptocurrency exchange in the world, redefining a user-centered approach to digital assets through real zero-fee trading, secured the third position among globally centralized exchanges, achieving 7.8% market share and recording $1.5 trillion in spot trading volume throughout 2025, according to Coingecko.

The exchange demonstrated exceptional growth of 90.9% compared to the previous year, significantly surpassing the industry average of 7.6% and solidifying itself as the fastest-growing platform among the top 10 exchanges. This momentum continued in December 2025, when MEXC processed $86.0 billion in monthly spot trading volume.
