A representative from Brazil's stock exchange, B3, said the stablecoin would be “a tool to enable trading in tokens," which it planned to offer in 2026. Brazilian stock exchange B3 announced a move deepening its ties to digital assets through the launch of a tokenization platform and stablecoin for settlements, starting in 2026. In a Tuesday notice to investors, B3’s vice president of products and clients, Luiz Masagão, said the exchange plans to launch a tokenization platform for traditional assets, starting with stock market offerings. He added that B3 would also issue its own stablecoin as “a tool to enable trading in tokens." “The great value of having this tokenization platform connected to the traditional ecosystem is that assets are fungible,” said Masagão. “The token buyer won’t know they’re buying from a traditional stock seller. This allows for a smooth transition, with both benefiting from the same liquidity.” Read more -

A recent study by the US Federal Reserve argues that despite periodic challenges, a lack of credible alternatives has kept the dollar at the center of global bond markets. A new Federal Reserve discussion paper finds that the US dollar’s role in global bond markets has risen and fallen in cycles over the past six decades, with no clear long-term trend toward either greater dollar dominance or de-dollarization. Using the Bank for International Settlements’ (BIS) international debt securities database, the authors identify three distinct “dollarization waves” since the 1960s, showing that shifts in currency use have followed cyclical patterns rather than a steady structural change in global financing. “We find no monotonic dollarization or de-dollarization trend; instead, the dollar’s share exhibits a wavelike pattern,” the paper says.

SOL falls behind multiple altcoin competitors as its onchain activity, fee and DApp revenues slump. Cointelegraph explains why. Key takeaways: SOL lagged the altcoin market as falling fees and DApp revenues signaled weaker Solana network demand. Growth shifted to Base, Arbitrum, Polygon and BNB Chain, reducing the odds of a near-term SOL rebound. Read more -

The values that are baked into the foundations of crypto — privacy, self-sovereignty, decentralization — are eroding, and we’re running out of time to address the problem. Not long before he died, Grandad said something that I thought was a little silly, a little old-fashioned. He declared that he didn’t trust the banks, and he didn’t want them to know what he did with his money. I scoffed at the time, paranoid old fella! But of course, it turns out I owe him an apology. As we were walking around his house, he motioned toward an off-white wall with an off-comfortable sofa in front of it. This piece of singularly ugly furniture hadn’t left its spot in more than a decade. Read more -

Bitcoin briefly clinched $90,000 after the November Consumer Price Index report showed a drop in US inflation, but the essential components for an extended rally remain elusive. Bitcoin (BTC) moved closer to reclaiming $90,000 after US inflation cooled more than expected, with the November CPI coming in at 2.7% year-over-year versus forecasts of 3.1%. The softer print narrows the gap to the Federal Reserve’s 2% target, easing near-term inflation pressure and reviving risk appetite across markets. Key takeaways: The lower-than-expected CPI print generated a positive response from Bitcoin as new positions opened versus the usual short covering. Read more -

Data suggests that fears about Xinjiang-related Bitcoin mining have overstated the impact, with hashrate losses proving brief and driven partly by US power curtailments. Recent claims of a major Bitcoin mining crackdown in China’s Xinjiang region rippled through the digital asset industry this week, but data by TheMinerMag suggests the actual impact was far smaller than early narratives implied. According to the latest Miner Weekly report, the Bitcoin network initially experienced a short-term hashrate decline, which was linked to developments in Xinjiang. However, the drop also coincided with power curtailments in the United States. Most major mining pools recovered to near pre-dip levels within days, resulting in a net decline of roughly 20 exahashes per second, which is significantly lower than the approximately 100 EH/s loss cited in early reports. “That points to a largely temporary disruption rather than a sustained, region-specific shutdown,” the report said.

US lawmakers are only considering de minimis tax exemptions for dollar-pegged stablecoins, according to Bitcoin Policy advocate Conner Brown. Representatives of the Bitcoin Policy Institute (BPI), a nonprofit Bitcoin advocacy organization, warned that US lawmakers have not included a de minimis tax exemption for Bitcoin transactions below a certain threshold. “De Minimis tax legislation may be limited to only stablecoins, leaving everyday Bitcoin transactions without an exemption,” Conner Brown, BPI’s head of strategy, said on X, adding that the decision to exclude Bitcoin (BTC) is a “severe mistake.” In July, Wyoming Senator Cynthia Lummis introduced a bill proposing a de minimis tax exemption for crypto transactions of $300 or less, with a $5,000 annual limit on tax-free transactions and sales.

In a recent Cointelegraph interview, James Check uses onchain data to challenge popular Bitcoin narratives and outline his thinking for 2026. Bitcoin’s price may look deceptively familiar, but according to onchain analyst James Check, the market beneath the surface has changed far more than most investors realize. In a new interview with Cointelegraph, Check revisits a question he was asked earlier this year: Are we in a bull market or a bear market? While Bitcoin (BTC) is trading near similar price levels, Check says that leverage, investor cost base, and sell-side behavior are now very different, and all those shifts matter. In fact, a majority of the capital currently invested in Bitcoin was acquired at higher prices, leaving many holders underwater and shaping a cautious sentiment. Read more -

The lawsuit against the memecoin launch platform Pump.fun, Solana Labs, the Solana Foundation and Jito was amended to include new evidence over MEV trading practices. A US court is once again being asked to weigh in on maximal extractable value practices after a judge allowed new evidence to be added to a class-action lawsuit tied to a memecoin platform.

ETH rebounded toward $3,000 as stocks reacted positively to a cooler-than-anticipated CPI print, but this week’s $553 million spot ETHER ETF outflow could keep a cap on prices. Key takeaways: US-listed Ether ETFs saw heavy outflows, signaling fading institutional interest as network fees, staking and leverage demand declined. ETH futures premiums and open interest declined, indicating cautious positioning and limited confidence, without a clear shift to outright bearishness. Read more -

Aptos has proposed an optional post-quantum signature scheme, citing long-term risks that advances in quantum computing could pose to existing cryptography. Blockchain network Aptos is moving toward a post-quantum signature option, reflecting growing concern that advances in quantum computing are no longer purely theoretical and could eventually affect how blockchain networks secure accounts and transactions. On Thursday, Aptos outlined a proposal to introduce post-quantum signatures, addressing the network’s reliance on digital signatures for ownership, transaction authorization and overall security. While existing cryptographic schemes remain secure against classical computers, researchers warn that sufficiently powerful quantum machines could one day forge them, potentially compromising account security retroactively.

Tether CEO Paolo Ardoino says an AI-driven bubble could shake Bitcoin, and shares his outlook on Europe, DATs and tokenization in 2026.

Ardoino shared his outlook on Bitcoin (BTC) and the broader crypto industry on Thursday during the Bitcoin Capital podcast, co-hosted by Bitfinex Securities and Blockstream. The executive said he sees Bitcoin “still too much correlated” to capital markets, thus potentially being impacted by the AI bubble, or a theorized stock market bubble growing amid the current AI boom.

“Pure play” digital asset treasury companies will have to contend with volatility tied to the net asset value of their token holdings if they don’t build successful business ventures. The rise of digital asset treasury (DAT) companies will go down as a meta-narrative of 2025, but the longevity of the movement will be decided by capital management and sound business strategies. According to Solmate CEO Marco Santori, all DATs have to contend with the value of the underlying token they hold on their balance sheets. This shouldn’t be a problem for revenue-generating businesses, but pure-play DATs will be in for a bumpy ride. In the Solana ecosystem, Santori sees a unique opportunity to offer bare-metal validator services, given that the protocol was uniquely designed for high-throughput services like exchanges and trading platforms.

Forensic analysis suggests an attacker took control of a whale’s multisig wallet minutes after creation and has been slowly draining funds since. A crypto attacker apparently took over a whale’s multisig wallet minutes after it was created 44 days ago, and has been draining and laundering funds in stages since. In a Thursday post on X, blockchain security firm PeckShield reported that a whale’s multisig wallet had been drained of roughly $27.3 million due to a private key compromise. PeckShield noted that the attacker has laundered about $12.6 million, or 4,100 Ether (ETH), through Tornado Cash and retained around $2 million in liquid assets, while also controlling a leveraged long position on Aave (AAVE). However, new findings from Yehor Rudytsia, head of forensic at Hacken Extractor, indicate the total losses may exceed $40 million and that the incident likely began much earlier, with first signs of theft dating back as far as Nov. 4.

Three major incidents accounted for the majority of crypto losses in 2025, while upgraded security across DeFi protocols managed to keep hackers at bay, according to Chainalysis. Crypto hackers focused on large crypto entities and personal crypto wallets this year, resulting in $3.4 billion in crypto losses in 2025 — the highest figure since 2022. Just three hacks in 2025, led by the $1.4 billion hack of crypto exchange Bybit, accounted for 69% of all losses from January through to early December, a Chainalysis report released on Thursday found, with the largest attacks a thousand times larger than the typical incident. Andrew Fierman, the head of national security intelligence at Chainalysis, told Cointelegraph that while massive attacks drove this year’s uptick in losses, it’s unclear if 2026 will unfold in the same way.
