Into the week's close, XRP is still trading above its monthly mid Bollinger Band, leaving a potential move toward about $3.6 on the table while defending the $1.82 area. Midnight (NIGHT), often framed as a "new Cardano" narrative play, has climbed roughly 40% over the past week, and Vitalik Buterin-linked wallets have been offloading BNB and other tokens into USDC and ETH amid a wider "crypto winter" tone. Traders are watching whether XRP can maintain this structure, NIGHT can clear $0.10 without losing key supports, and Buterin's wallets keep a defensive posture.

MSCI is reviewing whether to remove MicroStrategy and dozens of other listed companies with large digital asset holdings from its indices, with a decision expected by January 15.

On 21 December 2025, a discussion draft from Representatives Max Miller and Steven Horsford outlined proposed changes to how everyday crypto use is taxed in the United States. The plan would exempt up to $200 in qualifying stablecoin payments from capital gains calculations and allow certain staking and mining rewards to be deferred for tax purposes for as long as five years. The draft emphasizes routine payments and reward income rather than speculative trading, while maintaining anti-abuse rules and Treasury oversight.

U.S. Reps. Max Miller (Ohio) and Steven Horsford (Nevada) proposed a de minimis tax exemption for stablecoin payments of $200 or less. In July 2025, Sen. Cynthia Lummis advanced a similar $300 threshold that failed to pass. Banks oppose 3%-4% stablecoin yields, while industry leaders, including Tyler Winklevoss, are pushing back.

On December 21, 2025, Binance Futures launched USDS-margined perpetual contracts for ZKPUSDT, GUAUSDT and IRUSDT with leverage of up to 40x.

A draft crypto tax framework in the US House of Representatives, led by Rep. Max Miller and supported by Rep. Steven Horsford, proposes a bipartisan overhaul of how digital assets are taxed. The plan includes a de minimis exemption for regulated stablecoin payments under $200, clearer rules for tax treatment of crypto lending, and up to five years of deferral on income from mining and staking rewards. If formally introduced and passed, it could mark a major shift in how Americans use and report digital assets for tax purposes.
