Quarterly 13F filings show U.S. institutions reduced Bitcoin ETF exposure by roughly 25,000 BTC (~$1.6B) in Q4 2025 versus Q3: investment advisors cut ~21,800 BTC and hedge funds ~7,700 BTC, with brokerages and banks also trimming positions. The filings reflect reduced ETF positions (not direct on‑exchange bitcoin sales) and align with several weeks of net ETF outflows, which the summary says creates downside pressure until flows turn consistently positive. Separately, DeFi activity on Ethereum-based Mutuum Finance is expanding: >19,000 MUTM holders, MUTM trading at $0.04, $20.6M raised, 4 billion total supply cap, and a Sepolia testnet environment reporting $150M+ TVL; protocol features include P2C/P2P lending, mtTokens for depositors, staking rewards, plans for an overcollateralized stablecoin, and upcoming feature upgrades.

13F filings show a ~25,000 BTC reduction in ETF exposure (advisors ~21,800 BTC, hedge funds ~7,700 BTC) and the filings align with recent net ETF outflows—facts that imply short-term downside pressure on Bitcoin; the filings note reduced ETF positions (not direct exchange sales), which moderates but does not eliminate market impact. Mutuum growth is factual but pertains to an altcoin/DeFi project and is unlikely to materially change Bitcoin market direction.
