U.S.-listed spot Bitcoin ETFs recorded about $782 million in net outflows during Christmas week, with December 29 data marking the sixth consecutive trading day of redemptions and pushing the cumulative figure above $1.1 billion, BlockBeats reports. Friday saw the largest single-day withdrawal at roughly $276 million, including nearly $193 million from BlackRock's IBIT and around $74 million from Fidelity's FBTC, while Grayscale's GBTC posted smaller but steady outflows. Total assets under management across Bitcoin spot ETFs fell to approximately $113.5 billion from over $120 billion in early December, even as Bitcoin traded near $87,000 over the same period. Some institutional observers cited in the report said holiday-related outflows are typical and noted that January ETF flows, once normal trading resumes, may provide clearer directional signals.

Indian police in Hyderabad arrested a former Coinbase customer support employee on Dec. 29 in connection with an internal data breach disclosed by the exchange in May 2024, Coinbase CEO Brian Armstrong confirmed, BlockBeats reports. The investigation traced the breach to December 2023, finding that criminals bribed overseas support staff to access internal systems and steal sensitive data on 69,461 users, including names, addresses, phone numbers, emails and government-issued ID documents. Coinbase said attackers demanded $20 million; the company refused and launched a $20 million bounty program to help capture those involved. In its Q2 earnings, Coinbase disclosed $307 million in related expenses for user compensation, legal fees and security upgrades; the company faces a shareholder class action alleging delayed disclosure and investor misrepresentation, and said it continues working with international law enforcement.

Ethereum could trigger about $395 million in cumulative long liquidations on major centralized exchanges if its price falls below $2,900, Coinglass data cited by BlockBeats show. The same data show a move above $3,000 would correspond to roughly $497 million in total short liquidations across leading CEXs. BlockBeats noted that liquidation charts indicate the relative intensity of each cluster rather than exact contract values, with higher bars suggesting stronger price reactions driven by liquidity waves.

Bitcoin has gained about 27,701% since 2015, far exceeding silver's roughly 405% and gold's about 283% returns over the same period, leading crypto analyst Adam Livingston to call it a "top asset", Cointelegraph reported on Dec. 29. Gold advocate Peter Schiff countered that performance should be measured only over the past four years, arguing "Bitcoin's time has passed", while Orange Horizon Wealth co-founder Matt Golliher noted commodity prices tend to converge toward production costs as higher prices boost supply, contrasting this with Bitcoin's fixed supply. In 2025, gold reached around $4,533 per ounce and silver neared $80 as Bitcoin remained relatively flat and the U.S. Dollar Index fell nearly 10% for one of its weakest years in a decade. Arthur Hayes said looser Federal Reserve policy and a weaker dollar would support scarce assets including gold, silver and Bitcoin long-term.
