Daily brief: JPM Coin to Ethereum, Strategy golden cross, Witt exit

CoinDesk's daily briefing leads with three developments. JPMorgan will make JPM Coin — its token representing U.S. dollar deposits — available to institutional clients on the Ethereum network, extending the token beyond its private blockchain footprint; no launch date has been disclosed.

• Strategy's stock is approaching a golden cross, a technical signal that could mark a shift in momentum for the bitcoin treasury firm.
• White House crypto adviser Patrick Witt announced he is leaving government for the private sector, leaving the Trump administration's digital-assets office without a named crypto adviser.

The brief lands as banks push deposit tokens onto public networks, markets track technical signals in crypto-linked equities, and Washington's in-house crypto policy team thins out ahead of a fresh legislative push.
