Institutions aren’t leaving Bitcoin—they’re reallocating. While U.S. spot Ether ETFs soaked up multi‑billion inflows in August, Bitcoin quietly strengthened its institutional backbone: record July ETF intake, the SEC’s new in‑kind creations/redemptions reducing friction, and resilient on‑chain support in the low‑$100Ks after BTC printed fresh highs this month. The signal beneath the noise: big money still treats Bitcoin as the benchmark, even as it rotates into ETH for yield and a “new ETF” narrative.

What’s happening now

Bitcoin rallied to new highs in mid‑August before consolidating near $111k, with on‑chain support flagged around $107k–$109k and a broader band at $107k–$113k. U.S. spot BTC ETFs set record net inflows in July, then saw mixed prints late August as capital rotated into Ether ETFs—on pace for roughly $4B in monthly net inflows per multiple trackers.

The rule change enabling in‑kind creations/redemptions for BTC/ETH ETFs is a structural upgrade: it helps authorized participants move inventory more efficiently, tighten spreads to NAV, and reduce tax and slippage drag—critical for pensions, insurers, and RIAs deploying size.

Why this matters to traders

- ETFs now set the marginal demand curve for BTC in the U.S. Spot ETF flows are the cleanest proxy for incremental institutional buying or selling. - August’s ETH rotation does not negate BTC’s thesis; it reflects late‑cycle behavior where capital seeks relative value and yield. BTC retains the deepest liquidity and the clearest macro “digital reserve” narrative. - Post‑halving miner profitability improved in July, tempering near‑term forced sell pressure, while reduced issuance remains a steady supply headwind—supportive on dips, not a straight line up.

Key levels and data to watch

• Price: BTC holding the $107k–$113k band; a sustained reclaim above the top of the range can re‑ignite trend following. Loss of the lower band invites range expansion lower.
• Flows: Daily net flows for BTC/ETH spot ETFs (e.g., Farside). Watch for BTC’s tape turning consistently positive post month‑end rotations.
• Dominance: If BTC dominance stabilizes after easing, risk may rotate back to BTC leadership.
• Miners: Listed‑miner updates; rising profitability generally reduces treasury selling pressure.
• Macro: Dollar strength and rate‑cut odds; outsized USD moves can whipsaw crypto trends.

Strategy ideas for the rotation

• Core‑satellite: Keep BTC as the core exposure for liquidity and benchmark beta; use smaller, time‑boxed ETH satellites to express the rotation with defined risk.
• Flow‑first entries: Prioritize fresh longs when BTC ETFs flip back to consistent net inflows and price holds above $113k on closing basis; avoid chasing if flows remain negative.
• Range discipline: For spot, consider laddering bids within $107k–$109k and trimming into $113k–$116k until a clear breakout; set invalidation below range lows.
• Options: When price reclaims the band with improving flows, call spreads can cap premium while targeting continuation; use protective puts if holding through macro prints.
• Pairs lens: Watch BTC/ETH ratio—if ETH flow momentum stalls while BTC inflows resume, a rotation back to BTC leadership is likely.

Risks and invalidation

Prolonged BTC ETF outflows, a stronger‑than‑expected dollar, or a resurgence in miner selling could pressure the range. A firm daily close below the low‑$100Ks would argue for patience and reduced risk until flows turn.

September watchlist

• BTC ETF net inflows resuming as in‑kind plumbing settles post month‑end.
• BTC reclaim and hold above $113k with expanding spot demand.
• Miner profitability/trustee sales updates that affect supply overhang.
• Macro catalysts (inflation, jobs, policy headlines) that shift liquidity conditions.

Bottom line: follow the flows, respect the range, and let the improved ETF plumbing guide timing. Rotation is opportunity—if you manage it with structure and data.
