表面看是PEPE涨了12.7%（24h，市值排名第48），同时登上CoinGecko trending榜单（同口径+12.0%），谷歌搜索热度7天达29.6/100，是素材里所有追踪关键词中最高的。但真正值得拆的问题是：这波meme热度和同一天BTC现货ETF净流出6.36亿美元（10-22数据），到底有没有因果关系。
第一层机制很直接：涨幅榜上PEPE排第48，BONK同期24h涨7.0%，meme板块确实在普涨，不是PEPE一个币的独立行情，这种板块联动比单币拉盘更像是资金在板块内部找新故事。
第二层机制——也就是"为什么是现在"——目前看不出确凿证据。恐慌贪婪指数维持在50（中性），并没有滑向极端贪婪或恐惧，BTC本身24h几乎走平（-0.0%），7d也只回撤0.5%，谈不上"机构资金撤离、散户补位"这种教科书式风险下沉剧本。更关键的是，谷歌趋势里PEPE相关的热搜词大多是无关的娱乐、人名类搜索，可能存在同名词干扰，拿这个当"加密热度指标"本身就有噪声，不能直接当作散户FOMO（害怕错过）的实锤。
所以反馈循环这一格暂时写不满：没有证据显示ETF资金流出→散户转向meme币这条传导链条真实存在，两件事更可能只是同一天发生、彼此独立的信号。如果接下来几天meme板块持续跑赢，且ETF资金流出持续扩大，这条链条才算有迹可循；否则更可能只是一次短期、分散的板块轮动。
Surface read: PEPE jumped 12.7% in 24h (mcap rank #48), landed on CoinGecko's trending list at the same clip, and Google search interest over 7 days hit 29.6/100 — the highest among tracked keywords in this dataset. The real question is whether this connects to BTC spot ETFs posting a $636M net outflow on Oct 22.
First-order mechanism: it's not a lone PEPE pump. BONK rose 7.0% over the same 24h window, and the gainers list shows broad meme-sector strength, which looks more like capital rotating within the meme category than a single-token story.
The second-order "why now" doesn't hold up on current evidence. The Fear & Greed Index sits at a neutral 50, not tilting toward extremes. BTC itself is roughly flat over 24h (-0.0%) and down just 0.5% over 7 days — nothing resembling a textbook "institutions exit, retail rushes in" handoff. Worth flagging too: many of PEPE's related rising Google searches appear to be unrelated entertainment or name queries, likely keyword overlap, which makes the search-interest number noisier than it looks and not a clean proxy for retail FOMO.
So the feedback-loop slot stays empty for now — there's no evidence linking the ETF outflow to meme-coin inflows; they may just be two unrelated things that happened the same day. If meme-sector strength persists alongside continued ETF outflows, that chain becomes worth watching. Otherwise, this reads as a short, scattered sector rotation.
