▌US Lawmakers Propose Tax Relief for Small Stablecoin Payments and Staking Rewards
US lawmakers have introduced a draft bill for discussion that would alleviate the tax burden on ordinary cryptocurrency users by exempting small stablecoin transactions from capital gains tax, including a $200 tax exemption for stablecoin payments, and providing new deferral options for staking and mining rewards. According to the draft, if a stablecoin is issued by an issuer approved under the GENIUS Act, pegged to the US dollar, and trades within a narrow range of around $1, then users would not need to recognize gains or losses on transactions not exceeding $200.
▌Ethereum Community Foundation Responds to "50 Million USDT Phishing Attack": The Practice of Truncating Addresses with Dots Should Be Stopped
In response to the "50 million USDT phishing attack" incident, the Ethereum Community Foundation issued a statement on the X platform, stating that the practice of truncating addresses with dots (such as 0xbaf4b1aF...B6495F8b5) should be stopped immediately. Address information needs to be displayed in its entirety; hiding the middle part of the address causes unnecessary risks. Furthermore, some UI options provided by certain wallets and block explorers currently have security issues, which can actually be resolved. It is understood that the phishing attackers had previously generated an address with the first and last three digits identical. The victim, without carefully checking and copying the address, transferred 50 million USDT to the similar address generated by the phishing attackers.

▌Vitalik: Prediction Markets are a Cure for Emotional Outrageous Views
Ethereum founder Vitalik Buterin stated in an article on Farcaster that prediction markets are a cure for emotional outrageous views. Many users on social media exaggerate and claim "something will definitely happen" to create panic or attract attention, but they do not take responsibility for it. Prediction markets, on the other hand, involve real money bets and tend to reflect true probabilities, thus counteracting these "crazy views."

▌Australian cryptocurrency exchange CoinJar announces US expansion plans
According to CrowdfundInsider, Australian cryptocurrency exchange CoinJar announced its entry into the US market. The company already operates in Australia, the UK, and Ireland. This move to the US means CoinJar will operate within the US federal and state regulatory framework.
... As part of its US expansion plan, CoinJar will launch CoinJarAI, an assistant directly integrated into its cryptocurrency trading platform that "helps users access portfolio information and market dynamics." CoinJar is reportedly one of the few exchanges to "integrate AI-powered portfolio and market tools into its platform to enter the US market." In addition to operating in Australia, CoinJar has previously obtained licenses in Ireland and the UK, and its investors include DCG, BoostVC, and Blackbird Ventures. Cryptocurrency ▌IOSG Founding Partner: 2025 is the “Worst Year” for the Crypto Market, But Bullish on 2026 ▌IOSG Founding Partner Jocy posted on the X platform that 2025 is the “worst year” for the crypto market. OG investors experienced three waves of selling, from March 2024 to November 2025, with long-term holders (LTH) cumulatively selling approximately 1.4 million BTC (worth $121.17 billion): First wave (late 2023 - early 2024): ETF approval, BTC from $25,000 → $73,000; Second wave (late 2024): Trump's election, BTC surging towards $100,000; Third wave (2025): BTC remained above $100,000 for an extended period. Unlike the single, explosive distributions of 2013, 2017, and 2021, this time it's a multi-wave, sustained distribution. The past year has seen BTC trade sideways at its high point, a situation unprecedented in the past. BTC, which hasn't moved for over two years, has decreased by 1.6 million coins (approximately $140 billion) since the beginning of 2024. However, the other side of the risk is opportunity. From an investment perspective: Short-term (3-6 months): volatile range of $87,000-$95,000, with institutions continuing to build positions; Medium-term (first half of 2026): Driven by both policy and institutional investment, with a target of $120,000-$150,000; Long-term (second half of 2026): Increased volatility, depending on election results and policy continuity. Alex Thorn, Head of Research at Galaxy Digital, stated that Bitcoin will reach $250,000 by the end of 2027. The market is too volatile and unpredictable in 2026, but it's still possible for Bitcoin to reach a new all-time high that year. Currently, options market pricing indicates that by the end of June 2026, the probability of Bitcoin falling to $70,000 or rising to $130,000 is almost equal; and by the end of 2026, the probability of falling to $50,000 or rising to $250,000 is similarly close. This wide price range reflects the high degree of uncertainty in the market regarding the short- to medium-term outlook.
▌Casa Co-founder: Bitcoin's Quantum-Resistant Upgrade May Face a 5-10 Year Timeframe Challenge
Jameson Lopp, co-founder of Bitcoin custody company Casa, posted on social media that he has been publicly discussing the risks posed by quantum computing to Bitcoin for 18 months. His main conclusion is: "I sincerely hope that the development of quantum computing will stagnate or even decline, because adapting Bitcoin to the quantum-resistant era will be extremely difficult for many reasons. Quantum computers will not crack the Bitcoin network in the short term. However, a comprehensive overhaul of the Bitcoin network (and unprecedented fund migration) could take 5 to 10 years. We should have the best hopes, but also prepare for the worst."
▌Analysis: Bitcoin's RSI Against Gold Falls to Nearly Three-Year Low, Considered a Bull-Bear Boundary
The Bitcoin/Gold (BTC/XAU) price has fallen to around 20.
The price of gold per ounce is at its lowest level since early 2024, while the weekly RSI indicator for this ratio has fallen to around 29.5 (oversold zone), near a three-year low. Data shows that this RSI oversold zone historically appears near the bottom of bear markets, leading some analysts to believe this may indicate that Bitcoin is undervalued and has room for a future rebound. However, others point out that a break below this key support level could signal a weakening trend.

▌Hassett: Consistent with Goolsby's view, there is still ample room for interest rate cuts
White House National Economic Council Director Kevin Hassett stated that President Trump will appoint his own person as Federal Reserve Chairman, and once this happens, the Federal Reserve will no longer be a problem. Hassett stated that he believes the US economy has not fallen into a "job recession" and the situation of excessive inflation has ended.
Meanwhile, consistent with Goolsby's view, there is still ample room for interest rate cuts.

White House National Economic Council Director Hassett: Trump wants the Fed Chair to make independent judgments, and he is seeking a data-driven candidate for Fed Chair.
▌Fed's Hammark: More Concerned About High Inflation, Inclined to Keep Interest Rates Stable Until Spring
Fed's Hammark stated that after the Fed's three consecutive rate cuts at its past meetings, there is no need to adjust interest rates in the coming months. Hammark opposes recent rate cuts because she is more concerned about high inflation than potential labor market fragility. Hammark is not a voting member of the interest rate setting committee this year, but will become a voting member next year.
... “My base case is that we can keep interest rates at their current levels for some time, at least until spring, until we get clearer evidence that either inflation is falling back to target or there is more substantial weakness in the labor market,” she said in an interview with The Wall Street Journal’s Take On the Week podcast on Thursday. According to CME’s FedWatch Tool: the probability of the Fed cutting rates by 25 basis points in January is 21%, and the probability of keeping rates unchanged is 79%. The probability of a cumulative 25 basis point rate cut by March is 47.1%, the probability of keeping rates unchanged is 43.4%, and the probability of a cumulative 50 basis point rate cut is 9.5%.

▌The Real Impact of Quantitative Easing on Cryptocurrencies
If we are to discuss whether "quantitative easing (QE) is beneficial to cryptocurrencies," we must first acknowledge a disturbing fact: the entire history of cryptocurrencies has been within environments of very limited liquidity, and only a portion of these environments conform to the traditional sense of quantitative easing that followed 2008. The conclusion so far is that since cryptocurrencies became a true market, we have only a handful of relatively "clean" liquidity environments to study—and the most influential one (2020) was also the most unusual. However, this does not mean that the claim about quantitative easing is wrong. Rather, it is probabilistic: loose financial environments tend to favor long-term, high-beta assets, and cryptocurrencies are often the purest manifestation of this phenomenon.
However, when we delve deeper into the data, we need to distinguish between four factors: (1) balance sheet expansion, (2) interest rate cuts, (3) the dollar's performance, and (4) risk sentiment—because they don't always change in tandem. Markets rarely wait for liquidity to arrive. They often begin trading policy direction long before the policy mechanisms are reflected in the data. This is especially true for cryptocurrencies, which tend to react to expectations—such as shifts in policy tone, signals from balance sheet policy, and anticipated changes in the interest rate path—rather than to the slow, gradual impact of actual asset purchases. This is why cryptocurrency price movements often precede yield declines, dollar weakness, and even any substantial expansion of the Fed's balance sheet. In the short term, cryptocurrency prices remain influenced by market sentiment and position volatility, and their movements depend not only on macroeconomic policy but also on positions and leverage. Liquidity certainly helps, but it cannot override all other influencing factors.
