Crypto policy and market sentiment shifted sharply as Blockstream CEO Adam Back said early writings by Bitcoin creator Satoshi Nakamoto should not be treated as doctrine, the White House prepared a closed-door Aug. 19 meeting with SEC (U.S. securities regulator) Chair Paul Atkins, CFTC (U.S. derivatives regulator) Chair Mike Selig and executives from Ripple, Coinbase, Gemini, Polymarket, Nasdaq, NYSE, CME and DTCC without waiting for the stalled CLARITY Act (proposed U.S. crypto market structure bill), and Coinbase CEO Brian Armstrong said AI agents will eventually outnumber human wallet holders. Back was responding to Robin Linus's podcast claim that Nakamoto intended unlimited block-size growth under Moore's Law to push BTC to $1 million, and he argued instead that Nakamoto later recognized scaling limits and discussed Layer 2 (networks built on Bitcoin for scaling) and even "Bitcoin banks." Armstrong said Coinbase is building AiFi around USDC on Base and the x402 protocol (machine-to-machine payment standard), which has already processed more than $100 million with support from Google, Visa and Stripe. In markets, Bitcoin fell below its 200-week moving average (long-term trend indicator) and traded between $62,000 and $65,000 as U.S. spot ETFs recorded $389.7 million in net outflows during Aug. 10-14, the largest weekly withdrawal since early July, while Strategy raised $334 million through an MSTR stock sale to support its 840,447 BTC holdings and BitMine Immersion Technologies extended its ETH buying streak to 59 consecutive weeks, with 87% of its position in staking (locking crypto to earn yield).
