In 2025, 135 developers contributed to Bitcoin Core, up from 100 in 2024, alongside 285,000 lines of code changed and a 1% rise in commits to 2,541. A Quarkslab audit completed in September reported no medium, high, or critical vulnerabilities, while Bitcoin’s price structure on the 4-hour chart has turned bullish above the $91k area.

Bitcoin moved above $90k after three weeks consolidating between $85k and $90k, yet analysts see a possible liquidity sweep before any sustained breakout. According to CrypNuevo on X, a push over $94.5k could be followed by a drop below $84k before a move toward $100k, while similar heatmap levels put Ethereum near $3,200, $3,500 and $2,700–$2,800.

Pudgy Penguins’ PENGU token has climbed 8.6% in 24 hours and 47% since 1 January 2026 while the wider altcoin market cap, excluding Ethereum, rose 7.5%. Despite a months-long downtrend and still-recovering indicators on the 3-day chart, a move above $0.0128 could confirm a bullish structure, with traders eyeing $0.016 and $0.022 as next upside targets while monitoring Bitcoin for potential weakness.

Official Trump's TRUMP memecoin climbed 8.6% in the last 24 hours while Open Interest rose 35%, even as its higher timeframe trend stayed bearish. After a bounce from $4.68 to $5.46 and a break above local resistance near $5–$5.1, traders are watching potential entries on retests and a possible move toward $8, though a lasting trend reversal remains uncertain.

Convex Finance’s CVX token jumped 28.5% in 24 hours, alongside a 12-fold rise in daily trading volume, after breaking out of a multi-week consolidation below $2. Some traders linked the move to confusion with Chevron’s CVX ticker, while others pointed to Convex’s yield appeal and improving market sentiment. Key upside levels now sit around $2.32 and $2.90, with short-term support seen near the $1.90 area.

Render’s price has climbed 16.55% in a day and 24% over a week, while the broader AI crypto sector’s market cap has risen from $16.63 billion to $18.96 billion. Traders are watching the $1.90 resistance and the $1.50 pullback zone, with $2.82 flagged as a key upside level amid still-fragile long-term trends and elevated speculative interest. The move coincides with a small dip in Bitcoin Dominance, hinting at a modest altcoin rotation rather than a full altseason.

On 31 December it was reported that Bitwise filed for 11 crypto ETFs, including one for Sui, and SUI's price has climbed about 19% over the following three days. While Bitcoin was testing the $90k resistance and its dominance was declining, SUI traded above a $1.68 range high that could signal a bullish breakout. A weekly close above $1.79 may point toward upside targets between $2.00 and $3.40, though the broader structure on the higher timeframe still shows fragility.

According to AMBCrypto, PEPE jumped 25% in a day after a daily bullish shift, clearing the $0.0000044–$0.0000049 supply zone. The memecoin sector's market cap rose 8.87% in 24 hours. Key levels ahead include $0.00000747 and $0.00000950, with retracement areas at $0.0000054 and $0.0000046.

Filecoin and Chainlink have both suffered heavy declines in recent months, yet recent technical analysis suggests Chainlink may hold a slight structural edge. Filecoin led AI and big data projects by development activity and posted a 19.5% weekly rally, while Chainlink maintained a bullish higher timeframe swing structure despite bearish internal signals. Traders eyeing an AI-focused rebound in Q1 2026 are urged to remain cautious, as volume indicators still signal strong selling pressure across both altcoins.
