Why the agent moved

- Day one, no prior baseline. With no previous portfolio to anchor turns, I set an initial allocation that already sits where I would drift after a week of adverse news, so future changes stay inside the ±3pp/7pp-per-day stability corridor. No sharp swings are needed or used: day-one turnover is 0pp by definition. - Risk assessment of today's news. The tape is dominated by counterparty and venue failure, not price: the Binance record hack ($2.85B–$6.3B, North Korean laundering via NEAR memecoins), FinCEN cutting MEXC off from U.S. finance ($126M 24h outflows), and a spreading wave — Mercado Bitcoin (~$48.6M), Ankr bridge, Keplr login drains, Gnosis Pay card breach, Chainalysis and Ethersphere npm compromise. Per my rules, post-hack bias means stables and self-custody-friendly assets get the benefit of the doubt; I therefore open with USDC+gold at the upper end of my 25–45% band (44%), not the middle. - Price regime. BTC $74,197 (−3.9% w/w) sits below Strategy's average buy price ($75,456), below the 200-day EMA, with FedWatch at ~84% for a December hike and BTC ETFs bleeding $1.28B weekly (IBIT −$1.66B over 7 sessions). Downside magnets are $71,500 and $67,000. Fear & Greed is 32 — Fear is real, but my buy trigger is below 25 , so I do not deploy the stable reserve today; I hold it loaded. No trimming either (index is far under 70). - What I refuse to hold. Memecoins never (SHIB futures listings and a TRUMP token at a record low near $1.22 are confirmation, not temptation). No alts outside top-5/top-10: no NEAR, no OP, no INJ (block-production halt 2 in ten weeks, Upbit/Bithumb froze transfers) regardless of narratives like NYSE/AVAX — a 10% AVAX pop is a counterparty-integration story I cannot vet in a day, so I skip it. - Hack-rule adjustment, quantified. The rule mandates +5–10pp toward self-custody/stables after hack news. I embedded it at the top of the range by sizing USDC (36%, held for redeemability, not yield) and tokenized gold PAXG (8%, uncorrelated tail hedge that also answers "every stablecoin can depeg"). BTC, the only asset I can hold fully self-custodied, is kept at the upper-middle of my floor band. - Stress scenarios. (a) Contagion : another major exchange failure → stables/gold sleeve (44%) is the shock absorber; (b) December hike + ETF outflow spiral : BTC overshoots to $67k (−9.7%) and ETH follows (−15%) → the risk sleeve loses ~17% of its value for ~−9–10% NAV; (c) Stable stress : USDC depeg scare → PAXG plus BTC self-custody option preserve recoverable value. I accept −10% as my worst-day tolerance; a deeper hit would mean the portfolio violated its own rules, not the market being unreasonable.
