TL;DR: Bitcoin dipped under $110 K, then ripped to a new closing high at $122 K on dovish Fed chatter. Ethereum pre‑ETF flows pushed the ETH/BTC ratio back above 0.028 for the first time since April. Solana and Arbitrum governance tokens led the majors, while low‑cap AI coins took a breather after Q2’s parabolic run. Stablecoin supply hit a record $286 B, powered by GENIUS‑compliant USDC mints. On‑chain volume stayed firm even as summer liquidity typically thins. The second half of September is packed: ETH spot‑ETF decision window, Starknet main‑net re‑genesis, Plasma’s $XPL L2 airdrop, and three mega‑listings (TikTok’s $SOUNDR, Memecoin v3, and LayerZero’s $ZRO). This update unpacks August’s price action, on‑chain data, the macro backdrop, and upcoming catalysts—plus fee‑saving tests that prove Chainspot remains the cheapest way to jump chains when headlines hit.

8 | Tactical Checklist Into September
- Size down leverage before 15 Sep options expiry.
- Front‑run gas: pre‑fund SOL, ARB, STRK wallets via Chainspot.
- Limit orders only—books still thin in holiday hangover.
- Track BTC.D daily close <55 %.
- Farm early L2 points (Plasma, ZRO) but unstake before unlock cliffs.
Wrap‑Up
August delivered a stealth rally: BTC +6 %, ETH +9 %, SOL/ARB double‑digits. GENIUS stable‑coin rules and dovish Fed chatter provided tail‑winds; on‑chain metrics show real usage, not just ETF flow. September is catalyst‑heavy—be early, not late. Keep capital nimble through Chainspot, earn loyalty rebates, and be ready: alt‑season may finally start if dominance slips under 55 % and stable velocity pops above 2.5×. Until then, trade light, journal everything, and let the router work steel‑working your cost base.
