7) Mining & decentralization dynamics — Bitcoin difficulty ATH
- What: Bitcoin network difficulty reached another all‑time high; industry debate about miner centralization and smaller operators being squeezed by energy/capex needs.
- Why it matters: Higher difficulty favors larger, capitalized miners and may influence geographic/operational concentration of PoW infrastructure — a fundamental network resilience and governance consideration.

8) Prediction markets & alternative derivatives growth
- What: Kalshi’s weekly volumes surpassed $500M with average open interest near $189M, outpacing Polymarket per Dune analytics; prediction markets and ETP/derivatives issuance growing.

Simple hint summary
- Regulation + stablecoins are the dominant structural story: GENIUS Act rule‑writing, Treasury comments, and corporate intention to adopt stablecoins point to payments and cross‑border use cases scaling materially.
- Institutionalization of custody and tradfi products is advancing: BitGo IPO push, eased ETF listing standards and growing prediction/derivative venues indicate more regulated product rails and capital onboarding.
- Protocol upgrades & token issuance matter for long‑term utility: Ethereum Fusaka, native stablecoin chains (Arc), major protocol tokens (MetaMask) and privacy/scaling projects will determine composability and institutional integration over months.
