Sep 2 — Coinbase, banks, and altcoin access reshape crypto

• Coinbase acquired derivatives exchange Deribit — giving a US-listed firm control of the dominant BTC and ETH options venue, reshaping crypto derivatives market structure. • Strategy purchased 4,603 BTC for $369.7M after a 10-week pause — renewed corporate treasury buying provides a meaningful bid as bitcoin softens toward $77K. • Citi, Goldman, and other major banks are teaming up on a stablecoin venture — TradFi's direct entry into stablecoin issuance directly challenges Tether and Circle's dominance.
