Ethereum has fallen 13.92% over the past 365 days in 2025 and risks logging its most bearish annual record if December closes in negative territory, with less than 96 hours left in the month. The asset is trading around $2,929.60 after a 1.13% daily drop, while trading volume has slid 27.6% to $12.19 billion amid cautious sentiment, even as some community members still anticipate a strong rebound in 2026.

Bitcoin’s October 2025 ATH of $126,000 has been followed by extended consolidation, and several prominent commentators now lean bearish. On December 27, 2025, Ki Young Ju noted the sentiment shift while BTC traded at $87,448.61, down 1.36% in 24 hours and with $27.8 billion volume off 16.9%. Technicals highlight risks toward $67,000, with support near $80,600 and $74,111.

Solana is trading near $124 with support around $118–$120, while RSI and a sharp rise in trading volume hint at a potential price reversal toward $140. The network continues to draw DeFi and NFT activity, and a planned cross-chain bridge with Cardano plus strong interest in a Solana ETF and broader Bitcoin strength could support a modest 13% upside move.

Dogecoin's daily trading volume has surged 76% to $1.01 billion even as price fell 0.5% to $0.1254 in the past 24 hours. The hourly chart still shows a death cross and RSI near 35, highlighting selling pressure with oversold conditions. Year-to-date performance is down 61%, with institutional narratives in the mix.

On December 25, 2025, Blockstream CEO Adam Back argued that Bitcoin need not be redesigned to counter hypothetical quantum threats, saying Taproot's key tweak was recently proven post‑quantum secure. He suggested deprecating key‑path spends if CRQC ever emerged and criticized hash‑only formats, while BIP 360 advocates push stronger guarantees despite potential feature trade‑offs.

On December 25, a Bitcoin BTC/USD1 pair on Binance suddenly dropped by more than 70%, briefly trading below $25,000 before rebounding above $87,000. The move was described as a flash crash with low liquidity and potential large liquidations, while one DeFi researcher alleged manipulation without providing evidence. After the event, Bitcoin traded around $87,420.41 with a daily range between $86,411.80 and $87,956.88 and lower trading volumes.

In the last 12 hours, according to CoinGlass, Solana saw an 8,392% liquidation imbalance as $4.94 million in long positions were erased. SOL tested the $124.11–$125.42 death cross zone at $125.28 before sliding to $120.78, and it now trades at $121.43 with volume down 14.93% to $2.74 billion. RSI between 37 and 39 signaled mild oversold conditions, while short liquidations reached $58,170.

Binance founder Changpeng Zhao responded to a recent $50 million loss from an address poisoning scam within one hour by proposing real-time blacklist queries across the crypto industry. He believes coordinated blacklisting of wallets receiving such funds, supported by security alliances and better wallet design, could drastically reduce these attacks.

On December 24, 2025, Midnight developer Sebastien Guillemot said the team completed a key cryptographic step to enable direct interoperability between Ethereum and Cardano wallets. He cited support for Ethereum’s Keccak and Cardano’s Blake2b as the basis for a privacy-first layer that validates ownership without exposing user data.
