American Bitcoin, backed by Eric Trump, has moved ahead of Anthony Pompliano's ProCap Financial in total corporate Bitcoin holdings after adding over 1,000 BTC since the start of December, bringing its stack to 5,044 BTC worth about $443 million. While both firms continue accumulating BTC and the top 100 public companies now hold more than 1.08 million BTC, their share prices and other Bitcoin proxy stocks have come under heavy pressure amid heightened market volatility.

On December 15, 2025, OpenAI was selected as Yahoo Finance's Company of the Year even as it carried the largest losses ever recorded, tied to $1.4 trillion in spending plans. The firm shifted into a for-profit structure, struck massive deals with Microsoft, Oracle, AMD, Nvidia and others, and now reports 800 million weekly active users, $13 billion in 2025 revenue, and a private valuation of $500 billion. HSBC projects a $207 billion funding gap by 2030, while analysts warn that ambitious chip and data center investments have rattled partners and heightened competitive and financial risks.

Two Ethereum price charts shared on X outline separate bullish technical structures, one based on an inverse head and shoulders on the weekly timeframe and another on a Wyckoff accumulation schematic. The first setup, posted by Bitcoinsensus, sketches potential upside above $7,000 with an extended objective near $7,600, while the second, from Merlijn The Trader, maps a path toward the $10,000 region if Wyckoff Phase E "markup" unfolds. Both traders emphasize that these scenarios still require confirmation as the patterns evolve.

On Dec. 15, the Gensyn Foundation launched its $AI token sale on Sonar, offering 3% of the total supply. The event features an English auction with a $1 million FDV floor and $1 billion FDV cap, plus a Testnet bonus multiplier and a chance to receive a Gensyn-branded GPU workstation.

On 15 December 2025, Bitcoin's network saw a rapid, measurable drop in hash rate, with rough estimates pointing to nearly one-tenth of computing power going offline. Mining executives described the move as abnormal, and industry insiders attribute it to localized shutdowns in western China. The protocol is expected to rebalance via difficulty adjustments.

CoinGecko's 2025 ranking by mindshare shows Solana leading at 26.79%, with Base at 13.94% and Ethereum at 13.43%. Sui holds 11.77% and BNB Chain 9.05%, while XRP Ledger registers 4.68%. The list emphasizes attention and engagement across ecosystems rather than price performance.

Ripple began testing its U.S.-regulated stablecoin RLUSD on Optimism, Base, Ink, and Unichain, using Wormhole’s Native Token Transfers to support native multichain issuance. RLUSD operates under an NYDFS Trust Charter, and DefiLlama data shows 79.2% of RLUSD on Ethereum worth over $1 billion, with the remainder on XRPL.

Bitcoin Cash traded around $546 after dropping below $550, while Bitcoin fell sharply to about $86,700. The BCH price, down roughly 4% in 24 hours, faces the risk of further losses toward $500, $450 or even $380 if wider market weakness persists. Technical indicators such as the RSI near 47 and a bearish MACD crossover suggest short-term downside, though a rebound toward $600 remains possible if momentum improves.
